@remote moth Thats also now how you do it in Python
The proper way to calculate distance is
remote moth
@remote moth Thats also now how you do it in Python
yes, but this have also work in unity
spring ledge
I just showed you why it doesn't work 😄
remote moth
I just showed you why it doesn't work 😄
ok, thx
spring ledge
in the picture you'd see that with your calculation, the closer object is further away
remote moth
but now have i the old problem still, the Projectile go not in the correctly direction
hard rune
Hello, I'd like to try to make a game in 2D but converted in 3D, how's that possible?
spring ledge
What?
spring ledge
Not sure what you mean tbh
remote moth
but now have i the old problem still, the Projectile go not in the correctly direction
how can i do that he go correctly?
projectile:
void Update()
{
if((self.position.x < -15f)||(self.position.x > 15f)||(self.position.y > 8f)||(self.position.y < -8f))
{
Destroy(this.gameObject);
}
transform.Translate(transform.right * 5f * Time.deltaTime);
}
spawn projectile:
void SpawnProjectile(Collider2D[] enemys)
{
GameObject a = Instantiate(shootPrefab) as GameObject;
a.transform.position = new Vector2(self.position.x, self.position.y);
Vector2 dirToTarget = (GetNearst(enemys).position - a.transform.position).normalized;
a.transform.right = dirToTarget;
}
spring ledge
I mean, it's still just 2d, just when you draw your actual sprite (as in, creating the image itself, not something you do in Unity) you draw it as if seen from the side (a bit angled though)
hard rune
so all sprites should be angled?
and what about the character? is it possible to move foward and backwards?
instead of just through the X axis
like most 2D games
spring ledge
what do you mean?
plush coyote
That's just in art skills man
The game is basically a top down game
the art is not
hard rune
yea that
plush coyote
that's the only difference
hard rune
hmmmm
plush coyote
There isn't really any special programming at all
hard rune
im just trying to figure out
because in 2D the player can only move to the sides
and up and down
plush coyote
So, like, a 3D game???
spring ledge
What do you mean?
plush coyote
if you add a third dimension, its no longer a 2D game
spring ledge
Where in that video do I see that
hard rune
i just want to give a 3D vibe
plush coyote
I have no idea what you mean
hard rune
xD
plush coyote
it would look the same no matter the Z position
remote moth
hard rune
hmmm
plush coyote
Like, is Starcraft 2 a 2D game?
No
but it plays like one
Its still a 3D game in terms of the engine, though
scarlet fractal
I think there's also something called 2.5D?
spring ledge
2.5D is still 3D, just with planes of sprites in the 3d environment
plush coyote
Yeah, although I typically associate those with side scrollers
remote moth
.-.
spring ledge
Like Ragnarok
hard rune
scarlet fractal
so it's a 2D game using a 3D engine right?
hard rune
nvm thats 3d
plush coyote
well, technically all 2D unity games use a 3D engine
remote moth
spring ledge
I mean
spring ledge
You don't generally move in the third dimension, so sort of?
plush coyote
@remote moth There is nothing wrong with that code
you have to be getting the wrong position
for your target
remote moth
@remote moth There is nothing wrong with that code
he should go to the other object, but he don't do this
when the target is left, then the projectill go right, why is this so?
.-.
hard rune
@spring ledge @plush coyote
this is the kind of camera i mean
0:48
Children of Morta
plush coyote
camera is just looking down
straight down
The only reason it looks like its at an angle is because the artists drew everything at an angle
remote moth
Give that me a wrong position?
Collider2D[] TouchedEnemys = Physics2D.OverlapCircleAll(transform.position, Radius, 5 << LayerMask.NameToLayer("Gegner"));
Don't think so
remote moth
what is thenn the problem?
tropic inlet
5 <<?
isn't it supposed to be 1 <<
?
remote moth
5 <<?
isn't it supposed to be1 <<
?
@tropic inlet this doesn't changed anything
remote moth
Are you getting no collisions?
@tropic inlet no not this is the probleme
the problem is that the projectill move in the wrong direction #🖼️┃2d-tools message
tropic inlet
Oh, wow, cool. I didn't know you could directly assign to transform.right like that.
I gotta test that out some time
Where's the code where you move the projectile?
oh it's above
remote moth
the first code here -> #🖼️┃2d-tools message
tropic inlet
i only saw the block of code at the bottom
ok what if u
add this line of code in the projectile's update:
double drawDistance = 5.0f;
Debug.DrawLine(transform.position, transform.position + transform.right * drawDistance);
is the transform.right facing the wrong way?
remote moth
mhh, he look in the correct direction, but he go in the wrong direction
is the transform.right facing the wrong way?
@tropic inlet nope it is not
remote moth
so have fixed it:
wrong:
transform.Translate(transform.right * speed * Time.deltaTime);
correctly:
transform.position += transform.right * Time.deltaTime * speed;
why is my tilemap not correctly in the fileds? :o
remote moth
i have the problem that the texuters, not by the textures center are
solar thicket
@remote moth move that first child "textures" to 0,0,0 to center it on the pivot of 'tower'
solar thicket
@remote moth the pivot for a gameObject is always at 0,0,0, as far as I know. If you set the position of a child to 0,0,0, it will be exactly on the pivot of its parent (in this case, the center of 'tower'
so yeah, both mean the same thing here (but they are different concepts)

Hello there!
I've question about developing strategy game (turn based) in Unity. I've headache in terms how should I structure the game to make it okay. I've some minor gamedev background but in older engines like SFML, LibGDX etc. The question is, I do not really know how should I approach the game state here.
Should I have some sort of "low level" representation of game state and just use GameObjects to display things but handle game state "internally"? Or should I keep the game state in scene as a standard GameObject tree? I'm concerned that it will be really hard to handle strategy game using game objects in terms of making some AI for it, calculate paths, tie some sort of entity (like player unit) to particular place etc.
In more tradional game engine, I'd just keep game state and map in classes, arrays of tiles, etc, but I'm not sure how to crunch this in Unity. Do you have any suggestions for that?
solar thicket
the more stuff i do, the more i think 'model your game data independently of unity and use unity as a renderer' is the way to go
or maybe DOTS, which i think will be the best option eventually
wind socket
Thanks for your opinion. There is something going in my head that tells me that using scene object as "real" game state won't scale well for strategy game
solar thicket
I think the model of 'objects which exist and you attach behaviors to them' is really appealing and great for prototyping ideas...but yeah, for anything of any scale, I end up pulling things into higher level systems that control dumb 'visual' objects. If you want to have a crowd of units with collision avoidance, you're going to want that to be one loop, not a component on each unit in the crowd. Stuff like that.
wind socket
Very good points, thank you

cursive apex
Hey
I am making a 2D platformer and I want the camera to follow the player but only on the x axis. How would this be done?
plush coyote
Just don't change the y position when running your camera code? @cursive apex
public Transform playerTransform; // Get a reference to the player through the inspector
private Vector3 _cameraZOffset = new Vector3(0f, 0f, -10f); // An offset so the camera doesn't go directly inside the player
private float _lerpSpeed = 8f; // A variable to control how fast the camera lerps to the player position
private void LateUpdate() // LateUpdate so this executes after the player has moved already
{
Vector3 desiredPos = new Vector3(playerTransform.position.x, 0f, 0f); // Get our desired X position
transform.position = Vector3.Lerp(transform.position, desiredPos + _cameraZOffset, _lerpSpeed * Time.deltaTime); // Finally move the camera
}
Thank you! I will try it out
@plush coyote It works, but the player is shaking alot
plush coyote
You put this code on the camera right
plush coyote
Is the player a rigidbody?
cursive apex
Yes
plush coyote
Try turning on the "Interpolate" setting
or, switching the interpolation option to "Interpolate"
plush coyote
You might be able to use lower lerp speeds if you turn on interpolation
cursive apex
Hmmm i will give it a try

how do you make a sprite clickable?

Depends.. but you could use a collider and do this https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseDown.html
spark vessel
been tinkering with this script for a while to make two objects attach to each other. kinda hitting a brick wall. I can get the script to work correctly if i make the cookieObj a child of chef and change the script a bit.. but I want the cookie to move independently of the chef and then when he hits it attach to him. not follow him around as a child.
Anyone that can point me in the right direction I would be eternally grateful.
If I set cookie as a child of chef I can get it to work with this.
but again.. then i just have this cookie that randomly follows the chef around until they collide which isnt really what I want 😦

That works, but now it does not go forward. It just stays at the spot that it was shot from. Hmmmm
any ideas @undone coral
undone coral
Maybe it's z-axis is being adjusted and you're not using that? Try transform.right instead? Been a while since I've done this, sorry. :p

I don't understand why forward is not working
@undone coral
spark vessel
Hmm think i figured out my issue in part.. but im not sure what to do. My script triggers adding the fixed joint 2d between both objects. so component A is fixed to component B.

Not sure what to do with that.

Guys, when I translate position into world position from tilemap where does this position exist. In bottom left corner, middle or upper right of the tile?
glossy marten
Yeah I see now but I think there's something more
spring ledge
Would be better if you figure it out yourself, but yes, what the error is telling you is that you're trying to use a field (non-invocable, aka non-callable, since you do call methods using (), not fields) like a method, by attempting call it with ().
rugged kite
Wanna build RPG maker like event system and gonna probably overlap and check for colliders and get events

You do seem to know how to use fields, after all you did use it in Update()

@rugged kite may be middle not sure
glossy marten
@spring ledge I have done some research and english is not my first languange so it's too hard explanations everywhere, do you have any tips where I should figure it out?
still tendon
maybe
spring ledge
Well if you know that invoking (and thus invocable) are just fancy works for calling (so, callable) I guesst hats a first step
@rugged kite Got a tilemap?

never used tilemaps like that

@spring ledge not atm

Ah

sorry to say @spring ledge but you are not using beginner friendly words

That complicate things 😄
rugged kite
Planning my work on the fly
spring ledge
@still tendon Can always ask if they don't understand a word
spring ledge
The compiler doesn't use beginner friendly words either is the issue haha
spring ledge
Sure, but the compiler outputs "invocable"
not "You're trying to call a field"
@still tendon What words specifically though?
rugged kite
One important thing for begginers is to check what compiler does and how they can use its optimalization strategies in order to make themselves work less
still tendon
yeah
glossy marten
Whats the difference between GetAxisRaw and just GetAxis?
rugged kite
Eg compiler changes multiple ifs into switch automatically
So if switch bothers you go with ifs
tropic inlet
Whats the difference between GetAxisRaw and just GetAxis?
@glossy marten getaxisraw is always whole number

@rugged kite What do you mean with "translate position into world position" btw?

in acc form

Okay thanks

@rugged kite What do you mean with "translate position into world position" btw?
@spring ledge its transform
may be

If KeyCode is detected Get tile position and make it into world position, overlap circle, check if there's some event eg button and execute it
Wondering where the point of overlaps origin would be

@spring ledge Where can I learn about methods?

if it's a tilemap field, how can it be for cells 🤔
still tendon
@glossy marten i will recommend to go with a tutorial series at first
spring ledge
Think that just tells you what tile the tilemap as a whole is centered on?
spring ledge
i.e. where the gizmo would be too
glossy marten
I have watched a lot of tutorials but to learn programming is like to learn a whole new language
still tendon
yeah then you can just store position in a var to calculate the translations
I have watched a lot of tutorials but to learn programming is like to learn a whole new language
@glossy marten you can start with

You mean center/amount of tiles?

https://youtu.be/bPQx0paXrbw @glossy marten

@tropic inlet I just clicked on that video 😄
rugged kite
found it
Grid.GetCellCenterWorld
In a rectangular grid layout, a call to GridLayout.CellToWorld with Vector3Int parameter, returns a Vector3 coordinate that represents the bottom-left of the cell. This is mathematically correct, but when for example instantiating a GameObject into the grid, you often prefer the center of the cell instead.

for instantiating, i just need that for the rotation part so i can add my stuff like aimoffset to it

https://hatebin.com/wcittowbfb here is the entire script for it, i just kinda need that part to be fixed and it's fine
brave creek
sorry what?
brave creek
that's not really how instantiating works, it needs a whole rotation
not just the z axis
brave creek
https://hatebin.com/iuqogegqoo this, so it's a whole rotation (what instantiating requires) and a seperate vector3 or quaternion
brave creek
how would i do this correctly for rotations: https://hatebin.com/iuqogegqoo

like a tile that is dirt with water on top that has some transparency is fine

I've learned recently that u can just set the transform.right to make ur object point where u want
u just need the right direction vector

}
this is assuming transform.right is what u are treating as ur character's forward

Hey so i have recently come across a point of inefficiency in my game and want to make some changes specifically to the enemy attack mechanic in the game. Currently what i am doing in the damage player function (near the end of the script) is checking if the player is within 0.9 f units of the enemy and if it is it then attacks after a set time value, but this is extremely in efficient as the player can go in and out of the 0.9 f range and the enemy will not hit. So i attempted to check collision instead with the player but that was to no avail, using the on collision enter 2D function. Could you please help me refine the combat system as i feel it is extremely sloppy as of now. If you want to see a video in action of how the enemy ignores the player please do ask and ill be happy to make one and send it.

leaden hill
Howdy, so I'm trying to finalize my top-down building system. The last thing I have to do is show the area in which is buildable. How it works is a building must be placed within x amount of tiles from a "node". These nodes are also placeable, and is needed to expand the players buildable area.
My issue is I don't know how to visualize this. The best Idea I had was when a player enters building mode, it highlights all grid spaces red that the user cannot place in. I'm just not sure the best way to tackle this.
Here is what I mean. As you can see I have a grid overlay with the hub in the middle. By default, the player has control over 3 grid spaces out from the hub. But I want to visualize that when they enter build mode, so all other tiles outside of that area would become red when in build mode.
Also I should mention I didn't make this via a tile map. So that's my issue

Vector2 relative_vector = v2_L - v2_R;
Vector2 p3_perp = v2_R + ( v2_rotate(relative_vector, -90 * Mathf.Deg2Rad ));
float cur_dist = Vector2.Distance(v2_R, p3_perp);

2: if I try to drag the various sprites in multiple selection, the animation is created but I cannot then apply it to a sprite in the initial state
How can I solve?

So, you want to spawn and launch a projectile
and you want this projectile to have a rigidbody?

I don't know how to do networking.
I only know how to do it in singleplayer (or, well, offline) mode.
still tendon
Yeah, same
still tendon
All I have with networking so far is that someone can join the game and we can see each other shoot and move.
spring ledge
How does that work?
still tendon
still tendon
What do you use?
spring ledge
Well, haven't really used Unity for networking, but usually just sockets
still tendon
Ahhh, no problem thanks anyway
spring ledge
Not sure what networking model Photon goes for, I think peer-to-peer.
If so, you'd have one host be the authorative server and on that one, when the projectile hits a player the host decreases that players' HP and sends the new HP update out to all players
Or you could have an approach of like, each player manages their own HP, i.e. if the local client sees a projectile hit the player, it decreases HP and sends out an update for that.
Though the latter is more prone to be affected by cheating
Though it can get a lot more complex if you want to do fancy networking stuff to compensate for lag and such
still tendon
But I imagine that for the first scenario, if the person who is hosting the server quits than the whole game does as well?
spring ledge
Sure, some games have a mechanism that transfers hosting rights
Generally, if you want a game to run regardless of who is there, you'd go with some sort of dedicated server. Where you run the game (or at least the necessary parts of it) on a server that people connect to
still tendon
Would this work for larger games as well?
spring ledge
Which way?
still tendon
Like is that the system that large games like COD or fortnite would have multiplayer
spring ledge
Dedicated server is even better for anti-cheat because now there is no host who could cheat easily. But you of course need to provide your own server then :p
Think Fortnite would uses dedicated servers
CoD could be either way, since I think you can just create a server ingame
still tendon
So a dedicated server can host multiple games?
spring ledge
Sure? Dedicated just means that it's a server that exists for the sole purpose of people playing the game and such.
Instead of like, a player acting as the server.
Theres lots of decision to make about how you want your game to network :p
still tendon
Yes seems like a lot of information lol, very interesting
spring ledge
Sadly I picked that knowledge up from various sources over time, so I can't really provide a single guide or anyhting
Other than Valve's post about lag stuff, but tahts quite advanced

So I have a problem
It's about my character
I made all sprites for my character that's 32x32 pixels
So, when I put my character sprite in game
When I open scene you can see character sprite normally
But when you open "game" scene
It's like this
So I tried changing scale of character, it helped but it's not just right
It should be x 1 and y 1 , right?
One interesting fact that when I change scale of the whole "game scene" my character starts to change too
Maybe it's problem here?

Hello fellas ! I am having a bit of a trouble here : I have a simple script for a "spawn protection".
Projectiles go throught an empty BoxCollider2D set as a tyrigger one, get there CapsuleCollider2D disabled on enter2D and re-enable on Exit2D and then get destroyed (that part is working tho). That's what iit is suppose to happen.
using System;
using UnityEngine;
public class EnemySpawnProtection : MonoBehaviour
{
private void OnTriggerEnter2D(Collider2D other)
{
if (other.CompareTag("PlayerProjectile") && other != null)
{
other.enabled = false;
}
}
private void OnTriggerExit2D(Collider2D other)
{
if(other.CompareTag("PlayerProjectile") && other != null)
{
other.enabled = true;
}
}
}
The tag is OK (set correcly), I trully don't get why it is not working as the script is quite simple. The .cs is located on the BoxCollider2D GameObject.

hello, i have made an enemy AI following brackeys tutorial and am now making it so it runs when it is moving. For some reason it keeps like running then it plays idle but continues to move? please @ if you have any suggestions for fix
update, the enemy only runs when the player does
potent flower
@candid onyx your issue is that the ai it moves based on player input
candid onyx
oh right...
potent flower
the first line in your update
candid onyx
Yeah i see, so how would I make it so it was the velocity of the enemy?
the rigidbody2d is refrenced in another script and it also not on this component but instead the group or folder whatever its called
rigidbody is on EnemyObject, the script is on EnemyTest.
@potent flower
potent flower
I believe its
GetComponent<Rigidbody>().velocity
vocal condor
Well.. it's a vector 3 😛
potent flower
oops that gets you a vector3, try:
GetComponent<Rigidbody>().velocity.magnitude
candid onyx
btw im new so half this stuff goes over my head
potent flower
well getComponent<>() just gets the attached component on the gameObject, and through that you can get certain information that component holds
pallid stirrup
so i have my movement set on
rb.velocity = new Vector2(xmoving * speed, rb.velocity.y);
`but i want to add external forces
How could i do that?
potent flower
add the external force onto the end of that
vocal condor
Setting velocity will override forces.. perhaps use add force instead.
candid onyx
@potent flower to refrence the rigidbody, its in a different tab in the inspector?
potent flower
yeah that's probably the actual solution, but I figured you were handling it directly for a reason
potent flower
your enemy object should have its own rigidbody if you want it to move
and getcomponent<rigidbody> should grab it off the object
candid onyx
well im trying to get the component from the other thing
the code is on test, the rigidbody2d is on object
pallid stirrup
add the external force onto the end of that
@potent flower the velocity doesn't decrease then
it just gets added all the time
potent flower
if you are directly setting the velocity, you need to do all the drag math yourself as well
pallid stirrup
And what is exactly that math
potent flower
but Dalphats solution allows the physics engine to handle all the other stuff
pallid stirrup
Im sorry i don't really know 😅
The problem with dalphats solution is that my character will not have a set velocity
He'll accelerate then decelerate
potent flower
depends on what you are trying to accomplish, a general dampening is just velocity *= 0.9f; or something like that, you can do directional drag as well
adding force allows for that though
potent flower

vale coral
Why doesn't this send a message to console
I have given my player the tag Player already so if you say that is the problem you're wrong

probably means that the collider trigger isnt firing
which means you might want to double check your collider and rigidbody setup

https://docs.unity3d.com/Manual/CollidersOverview.html chart at the bottom of this page shows which rigidbody pairs will send messages by default
if you can't be bothered, project settings -> physics

and where

add it as the first line of update, i suspect it's always returning false which prevents jump from being called

what appears in the console?
stuck yacht
Nothing. There's no errors just the assosiated script cannot be loaded thing
still tendon
stuck yacht
Let me restart unity to see errors
still tendon
Do you know how to get the jumping to work
Cause the left to right is fine
and gravity is fine
I added the debug
sweet swan
if you just want to see the jump work, change the if statement to this:
if (Input.GetButtonDown("Jump")) {
Jump();
}```so just getting rid of the broken ground check
also next time collapse your console because if it returns true and false when youre in the air when you're on the ground then we'd know it works
still tendon
Could you add it into the code?
Or is it just on the end
I just dont want to lose the tutorial
sweet swan
mmmmmm true
if that's the case, here's some things i'd make sure are the same in the tutorial:
- the way groundLayers is set up
- every gameobject with a collider's layer
- the position of the feet's transform relative to the player
still tendon
I mean it is a big complaint in the comments that the jumping wont work, so its not like I am the only one
sweet swan
yeah i'm not surprised, afaik the best way to go about ground checks is with a dedicated foot collider and collision callbacks
casts don't use the matrix under project settings -> physics which makes them harder to maintain
still tendon
What should I do then- a different tutorial? Add the jump code in but carry on the tutorial? Just keep going on the tutorial?
sweet swan
this seems promising
i'm afraid i don't know the specifics of this series so i might not be able to help more than that
still tendon
But I have created a ground tag, and added it to the Ground + Platform, do you think I need to have the ground tag on anything else?
sweet swan
you know what set ground layers to everything and see if it works
if it still doesn't, then we'll know it's probably a bug with foot placement
still tendon
ground layers = Ground?
sweet swan
if it's set to ground, the ground should be on the ground layer
tag is largely irrelevant for physics
still tendon
may be a simple question; although How do I make an AI look in the way it's working? e.g If X is increasing look right, X is decreasing look left, Y is decreasing front sprite Y is decreasing behind sprite etc?
sweet swan
sounds like a blend tree to me https://docs.unity3d.com/Manual/class-BlendTree.html

Any idear how to get a GameObject (that is already instanciate) into an prefab ?
sweet swan
drag from hierarchy window to project
@amber geyser i'd have the sword slash be a separate gameobject that handles hitboxes and damage
if you have a bullet class, the slash can extend it
swinging the sword spawns the slash prefab
honestly you might as well find what works for you and use the profiler to decide whether it's performant
amber geyser
swinging the sword spawns the slash prefab
@sweet swan Thx for the answer. But if I instantiate another animated gameobject I should sync its animation with my character somehow. How can I do it?
sweet swan
i typically use an animation event at the start of the chara's swing animation to spawn the sword slash at the same time
or on the first frame the slash comes out if you're using anticipation frames
amber geyser
Aha, thx! Can you give a tip about correct architecture of such animators?
It should be a component which handle all View-related things like child gameobjects, animator etc I think
or may be good reusable example?
I think it should implement some interface to be reusable?
sweet swan
afaik this is the most reusable thing about the animator component https://docs.unity3d.com/Manual/AnimatorOverrideController.html

Hi, could use some help with creating a patrol route for an npc in game I started working on. I have a MovementController script used by player and npc. I want to create a route for npc to move around but when I pass the waypoint transform the NPC move in odd way.
So moves to the waypoint but just continues going. And if I move the waypoint to other side it heads there but at slower rate. Using a Character Controller but tried with a rigidbody2d and its the same. Player movement works just fine.
NPCController:
private void Update()
{
RouteBehaviour();
UpdateTimers();
}
private void UpdateTimers()
{
_timeSinceArrivedAtWaypoint += Time.deltaTime;
}
private void RouteBehaviour()
{
var nextPosition = _initialPosition;
if (patrolPath != null)
{
if (AtWaypoint())
{
_timeSinceArrivedAtWaypoint = 0.0f;
CycleWaypoint();
}
nextPosition = GetCurrentWaypoint();
}
if (_timeSinceArrivedAtWaypoint > waypointDwellTime)
{
Debug.Log("Moving to: " + nextPosition);
_movementController.StartMoveAction(nextPosition);
}
}
private void CycleWaypoint()
{
_currentWaypointIndex = patrolPath.GetNextIndex(_currentWaypointIndex);
}
private bool AtWaypoint()
{
return Vector2.Distance(transform.position, GetCurrentWaypoint()) < 0.1f;
}
private Vector2 GetCurrentWaypoint()
{
return patrolPath.GetWaypoint(_currentWaypointIndex);
}
And the MovementController:
public class MovementController : MonoBehaviour, IAction
{
// Animator properties
private static readonly int Horizontal = Animator.StringToHash("Horizontal");
private static readonly int Vertical = Animator.StringToHash("Vertical");
private static readonly int LastHorizontal = Animator.StringToHash("Last_Horizontal");
private static readonly int LastVertical = Animator.StringToHash("Last_Vertical");
// Movement configuration
[SerializeField] private float movementSpeed = 2f;
private ActionScheduler _actionScheduler;
private Animator _animator;
private CharacterController _characterController;
[NonSerialized] public Vector2 Destination;
[NonSerialized] public bool IsMoving;
private void Start()
{
_actionScheduler = GetComponent<ActionScheduler>();
_characterController = GetComponent<CharacterController>();
_animator = GetComponent<Animator>();
}
private void FixedUpdate()
{
UpdateMovement();
UpdateAnimator();
}
public void Cancel()
{
IsMoving = false;
}
private void UpdateMovement()
{
var direction = new Vector2(Destination.x, Destination.y);
var motion = direction * (Time.deltaTime * movementSpeed);
_characterController.Move(motion);
}
private void UpdateAnimator()
{
_animator.SetFloat(Horizontal, Destination.x);
_animator.SetFloat(Vertical, Destination.y);
if (!IsMoving) return;
_animator.SetFloat(LastHorizontal, Destination.x);
_animator.SetFloat(LastVertical, Destination.y);
}
public void StartMoveAction(Vector2 destination)
{
_actionScheduler.StartAction(this);
Destination = destination;
}
}
Code is terrible but I'm new to unity and this is just a prototype so be gentle please. 🙂 The destination that's passed in to character controller seem to be find and match the waypoint.

Collisions should be occurring by default if you're using 2d colliders and at least one of the two objects have a Rigidbody2D.

Hello! Can I use SpriteAtlas for making animations in Editor?
vocal condor
Unless they (the colliders) are set to trigger.

Are physical collisions not happening? Or the events triggered by collisions ? @tacit sluice
tacit sluice
Physical collisions
ruby karma
ok, so do you have non trigger colliders on both objects?
tacit sluice
Yes
ruby karma
Can you post screenshots?
ruby karma
Have you disabled any layer based collisions? are both the objects on the same Z position?

Ideally if one of the two objects have a Rigidbody and both have colliders that are set to non-triggered a collision should occur; assuming both are of the same type(2d/3d) and simulated.

recording a clip, be with you soon
both on z level 0, z level locked on rigidbody
the colliders are non-triggered

cache this with healthPlayerCollision = FindObjectOfType...; and access newHealth with healthPlayerCollision.newHealth
rmbr to declare it as a class variable too, so add HealthPlayerCollision healthPlayerCollision; at the start of your script

- use getcomponent + a collision callback
- make the other script a property and drag it in from the inspector
- cache the return value of instantiate
if you still need help i can take a look at your classes and implement it if it seems simple
lavish spire
Like that? I'm basically new to programming and I can't really understand referencing yet :<
robust ivy
you first declare a variable, in this case you want healthPlayerCollision to be that newHealth variable
so if your newHealth is a int
you do:
int healthPlayerCollision = FindObjectOfType.....
declaring variable in a function will only be usable in that function
if you declare it like your public variable up in your script then its usable everywhere
all the red underlined text you have in script are missing reference like this
either variable is not declared or not referenced to something in another script
also at the end of a line, add the ;, unless its a if and you open parenthesis { }, thats considered like a ; (which mean return/enter/process the code before that end point)
In your specific case, you dont really need to find that object variable in the
Awake menu, also its a bad idea to try finding other object in awake, the other object might not be there and ready yet so it could return null.
you could just do if (FindObjectOfType<HealthPlayercollision>().newHleath = 0

So i am trying to make a UI, but the UI thing won't work. I made a Button and a code that did SceneManager.LoadScene("Scene"), but when i click it. Nothing happens. I have tried to debug it and everything, but no

Does the debug shows in the console?
if yes its a issue wht the loading of the scene

Hi guys, currently my shooting works fine but i have one small bug. Due to a mechanic in my game where I flip the character to the left or right(depending on where the cursor is) and the gun always pointing to the cursor. Due to this when you put the cursor directly below you and quickly strafe left and right the bullet will spin
{
currentAmmo--;
allowFire = false;
GameObject bullet = Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
Rigidbody2D rb = bullet.gameObject.GetComponent<Rigidbody2D>();
rb.AddForce(firePoint.right * bulletForce, ForceMode2D.Impulse);
yield return new WaitForSeconds(0.2f);
allowFire = true;
}```if you would like the player flipping methods here you go:
{
if (facingRight == true && direction.x<0|| facingRight == false && direction.x > 0)
{
Flip();
}
}
void PointGun()
{
gun.transform.right = direction;
if (facingRight == false && gunRight ==true)
{
FlipGun();
gunRight = !gunRight;
}else if(facingRight==true && gunRight == false)
{
FlipGun();
gunRight = !gunRight;
}
}
void Flip()
{
facingRight = !facingRight;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}```all of which are called in input
except for flip

try with this instead?
public Vector2 vel;

public byte AmountPlayer;
void Awake()
{
Player = GameObject.FindGameObjectsWithTag("Player");
foreach (GameObject s in Player)
{
PlayerScr[AmountPlayer] = s.GetComponent<Movement>();

using Linq;
PlayerScr = GameObject

@brave creek does this work?

it says gameObject[] doesn't contain a definition for FlatMap
clever sky
Are you using Linq?
brave creek
yeah i'm using System.Linq

Is there a specific reason you're using GameObject[], or would List<GameObject> suffice?
Also it's Select and not FlatMap, that's my mistake
brave creek
never used List<GameObject>, but what i'm trying to do is grab all Players with the tag "Player"
okay yeah now it works, thanks!

Spreading a little of functional programming goodies never hurt
@brave creek I can btw tell you why you get an out of bound exception
Array's in C-like languages has a set size, so if you don't initialise it with the right size, then you'll get an out of bound exception
Let's take the following two arrays:
int[] ArrayOne = new {1,2,3}
int[] ArrayTwo = new {2,4}
While we can do something like (you're just reassigning ArrayTwo)
ArrayTwo = ArrayOne
We cannot say
for (int i = 0; i <= ArayOne.count; i++)
{
ArrayTwo[i] = ArrayOne[i];
}
Because then you'll get an out of bound exception because ArrayTwo[2] doesn't exist
brave creek
huh, late reaction due to having to close discord for some time, but thanks!

Hi guys, having an issue with how an npc I have moves. I have this simple patrol rout and the npc gets to it, waits for 1.5 seconds and then moves to next waypoint, but when moving to next waypoint it starts of at very high speed instead of constant speed of 2f and kind of slides to spot.
What's wrong with the script I have, this is used for both player movement and npc, but works fine with player?
private void FixedUpdate()
{
if (_isMoving)
UpdateMovement();
UpdateAnimator();
}
public void Cancel()
{
_isMoving = false;
_destination = new Vector2();
}
private void UpdateMovement()
{
var direction = new Vector2(_destination.x, _destination.y);
var velocity = _rigidbody2D.position + direction * (Time.deltaTime * movementSpeed);
_rigidbody2D.MovePosition(velocity);
}
public void StartMoveAction(Vector2 destination)
{
_actionScheduler.StartAction(this);
_destination = destination;
_isMoving = true;
}
And NPC controller:
private void Update()
{
PatrolBehaviour();
UpdateTimers();
}
private void PatrolBehaviour()
{
var nextPosition = _initialPosition;
if (patrolPath != null)
{
if (AtWaypoint())
{
_timeSinceArrivedAtWaypoint = 0.0f;
CycleWaypoint();
_movementController.Cancel();
}
nextPosition = GetCurrentWaypoint();
}
if (_timeSinceArrivedAtWaypoint > waypointDwellTime)
{
var offset = nextPosition - (Vector2) transform.position;
_movementController.StartMoveAction(offset);
}
}
Illustrating what I mean on gif, the two gizmos are the waypoints, you can see it shoots of really fast and then slows down near waypoint. Also slides into place.;/
offset.normalized is the answer... 😄

I am getting the following error " error CS0122: 'Movement.m_Grounded' is inaccessible due to its protection level" on this line of code
I am trying to access another scripts component, and it says protection level is too high

Presumably m_Grounded is private or something like that
If you want to access it like that from another script, you need it to be public

I'm having a problem with Rigidbody 2D. Im moving my player using RigidBody.velocity. This has worked fine since I implemented it, however, all of a sudden my player transform isn't being updated anymore. The velocity is applied to the rigidbody, but its not moving the player. Any ideas as to why this is happening?
sweet swan
some possibilities:
- transform.position or rb.position is being set elsewhere
- rb.velocity is being overwritten by something else
- rb is kinematic or static
mild saffron
transform.position isnt being set elsewhere, the only place I apply velocity is in the movement script and its being applied as expected just not reflecting onto the player, and rb is dynamic.

I made a text box with TMPro as a child I want the text box to flip when the player changes direction but don't want the text to flip

So, I have a system where the player flips depending on which way they go. Is there a way to apply that same code to the weapon by not typing it all out again?
still tendon
Well yes, I guess my question refers to the projectile coming out of the weapon
So the weapon flips just fine, I just need the bullet to

well, in what direction does the bullet move?
tropic inlet
What Brackeys did was instead of inverting the scale
he rotated the actual gameobject iirc
still tendon
okay thanks
tropic inlet
well, that was to make sure the object he was using to determine the spawn point of the bullet
would rotate with the player
i think it may have fixed the bullet thing too? Idk, I'll check the vid real quick
but if u are moving the bullet based off, like, bullet.transform.right or w/e, and the bullet's rotation is based off the player's rotation at the time of firing, I would assume rotating the player would make sure the bullet goes in the correct direction

I finally got my player to shoot bullets. But it has no collision. How can I fix it?
dark pumice
- Both parties in any collision need to have one of the 2D collider components attached, even if its just a wall.
- At least 1 object in any collision needs a Rigidbody2D
You can see more here: https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html
stuck yacht
Thank you\
stuck yacht
Yea both have a collider but theres still no collision
still tendon
is it 2d or 3d
dark pumice
yeah, careful, Unity is quite stealthy with physics ambiguity
OnCollisionEnter()
for 3D objects
OnCollisionEnter2D()
for 2D objects, that can trip you up easily
and also check that your rigidbody is not Rigidbody but Rigibody2D
and that your colliders are not Collider but Colider2D

How would I go about spawning a gun on the spawner, that the player can pick up
cinder veldt
// start by coding a gun that the player can pick up..
// turn that into a prefab
// instantiate the prefab @ the position of the spawner
still tendon
and then how would the player pick it up
cinder veldt
you would have a trigger on the pickup so when the player interacts with it, it disables / destroys the pickup gun and enables the players gun instead
still tendon
So the game has multiple guns. Would I have all the guns present on each player and whenever they interact with that gun. It would be enabled?
cinder veldt
thats the easy way of doing it yes..
u build one gun with functionallity on teh player..
set that gun active whenever u pick it up
then the pickup gun can be destroyed..
still tendon
and then when the gun is enabled, I can set the animation of them running with that certain gun active?
still tendon
ooooo much better way of doing it, I see
cinder veldt
then when u have a different gun or its put away you just disable it / de-active it
still tendon
okay thanks.

robust ivy
is a collider on trigger maybe?
delicate bramble
Nope
The circle is a kinematic rigidbody with full kinematic collisions
and the rectangle is a static rigid body
Most of the time they collide properly (as you might be able to see in the first image), but not always
delicate bramble
The Use Full Kinematic Contacts checkbox is marked, which I believe does the same thing
chrome fern
@tropic inlet and @cinder veldt You helped me solve my problem, I have trigger and collision destroys for the bullet, it was one of the triggers that was causing the issue. It's weird though, I had other scripts where it worked. Thank you.
craggy kite
@delicate bramble are you moving the objects by script?
delicate bramble
Yes, I am using MovePosition
Only the circle moves though, the rectangle is stationary
craggy kite
MovePosition is like moving a transform directly right, it does not really work with the physics in unity
delicate bramble
How should I move a kinematic Rigidbody then?
I thought the point of MovePosition was to enable that
craggy kite
from unity docs: If the rigidbody has isKinematic set to false, it works like transform.position=newPosition and teleports the object to the new position (rather than performing a smooth transition).
delicate bramble
The rigidbody is kinematic
craggy kite
than you should use forces I think
Oh wait, nope. read this: https://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html
like the first sentence will tell you, its not possible as you want it to happen
delicate bramble
I was looking on the Rigidbody 2D reference, and it says "Because this feature allows a rigidbody to be moved rapidly to the specified position through the world, any colliders attached to the rigidbody will react as expected i.e. they will produce collisions and/or triggers."
Also, even if the rigidbody is being moved by script, it still should collide right?
That's the point of Kinematic Rigidbodies right?
craggy kite
Nope, if its kinematic, moving it is like teleporting it, it might collide some times, but is not really controlled and checked by the unity physics system in a reliable way
delicate bramble
So are the docs wrong? any colliders attached to the rigidbody will react as expected i.e. they will produce collisions
craggy kite
If the rigidbody is kinematic then any collisions won't affect the rigidbody itself and will only affect any other dynamic colliders.
thats also in that doc site you posted.
delicate bramble
I don't need it to be affected
I just want it to call OnCollisionEnter
Which it usually does
But not always
craggy kite
So either you are moving it to fast and it will miss the collision enter call in physics, or its the kinematic part, which I am thinking is the problem. Just try for testing to non kinematic colliders, make a simple addforce script on mouse click or whatever and check if the same movement gives you bette rresults.
delicate bramble
ok
