well, you can show me the changes you made

i don't know what log statements you added
i would also want to see the code that actually checks if you pushed the "c" key
the code you shared doesn't appear to do that.

Hey does anyone know how people usually handle ammo using scriptableObjects? I set the max ammo and and the current ammo as variables in the scriptableObject but decreasing the current ammo in the scriptable Object changes the value even after the play session. I thought about setting the current ammo as a variable in the weapon controller but it doesnt keep the data when switching weapons.
lusty socket
the code above is the entire code from the video i followed it just said to add it as an axis in the project manager
this is the change i made

swift crag
Nowhere in your code do you check if the "C" key is pressed. Of course it doesn't do anything when you press C!
swift crag

In the editor, the SO object will only unload when nothing is left referencing it
it'll persist from play session to play session
I would suggest not storing mutable data in there.
Just store the configuration for the weapon. You should have a Weapon component that actually holds the current amount of ammo in the weapon
So the WeaponData ScriptableObject would have max ammo, damage, color, projectile speed...
and the Weapon component would have current ammo, time until next shot, etc.
lusty socket

where would you add the c press code, inside the void move or at the top, also what is the correct code to type to make the void move begin ? thankyou
swift crag
well, you would use something like Input.GetKey(KeyCode.C) to decide if "C" is being held
perhaps you could assign that into crouchPressed

I have a question. I have this code to make it so if timer reaches 0 the games restarts, and i have also (in another script) that when i press R the game restarts. The second works, but this one right here it does not. im unsure on what im doing wrong
using System.Collections;
using System.Collections.Generic;
using UnityEngine.SceneManagement;
using UnityEngine;
public class ControlJuego1 : MonoBehaviour
{
public GameObject personaje;
public GameObject bot;
private List<GameObject> listaEnemigos;
float tiempoRestante;
void Start()
{
ComenzarJuego();
}
void Update()
{
if (tiempoRestante == 0)
{
ComenzarJuego();
}
}
void ComenzarJuego()
{
SceneManager.LoadScene("facu parcial 1");
StartCoroutine(ComenzarCronometro(10));
}
public IEnumerator ComenzarCronometro(float valorCronometro = 10)
{
tiempoRestante = valorCronometro;
while (tiempoRestante > 0)
{
Debug.Log("Restan " + tiempoRestante + " segundos."
+ " Se reiniciará el juego");
yield return new WaitForSeconds(1.0f);
tiempoRestante--;
}
ComenzarJuego();
}
private void LateUpdate()
{
SceneManager.LoadScene("facu parcial 1");
}
}
The way I did it is in my Inventory manager I would instantiate the model based on the currentWeapon SO data. Then I would destroy the model when switching weapons. Is this bad practice? Should I instead attach a Weapon script and set the variables to the weapons SO and set them inactive when switching
swift crag
That sounds great. Just put the data that changes on the prefab you spawn.
so the prefab would have a Weapon component on it

Does your debug not show it ticking down? Looks fine to me

I do not have anything visual to make it so "it hits 0" i just use the phone timer 💀
Because i wanna make sure it works first before making it fancy and putting a timer (bc i dont know how to)

Well, the visual is it restarting the scene, does it not?

It does not reset the scene after 10 seconds passed.
It does reset when i press R tho. (i have a script for that)

sharp bloom
Trying to create something that constantly rotates back and forth in specified angle
This works somewhat...but if I set the rotation rate too high it breaks
swift crag
you should use >= and <=, not ==
sharp bloom
I assume it's because of my rounding thing
swift crag
you might miss the limit entirely
sharp bloom
you should use `>=` and `<=`, not `==`
Well wasn't that an easy solution lol. Thanks.
swift crag
You can get rid of that rounding
well, truncating
ah, I'm wrong there! Convert.ToInt32 rounds the float.
int angleInt = (int) currentAngle; would truncate
sharp bloom
You can get rid of that rounding
Yeah I figured it wasn't the right solution. Like you said it would sometimes allow the rotation to go past the limit.
sharp bloom
Trying to create something that constantly rotates back and forth in specified a...
But now I have a different problem...sometimes it gets "stuck" at the upper or lower limit for a couple of seconds
Where as I would expected this 90 degree arc for example, constantly
timber tide
pretty
swift crag
Try logging currentAngle. It might not be doing what you expect
notably, euler angles can abruptly change (on all three axes!)
to see this for yourself, spawn a cube
set its X rotation to 90
then give it a tiny rotation around the Z axis (the blue circle)
do this in Global mode
end result: both Y and Z abruptly jump to 90
I prefer to directly compute the rotation I want
For example:
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
sour fulcrum
oh does changing global-local setting in the scene view change what you see in transform inspectors too?
swift crag
This will set the transform's rotation to be spun angle degrees around hte Z axis
swift crag
oh does changing global-local setting in the scene view change what you see in t...
No, it's just necessary to get this exact effect
although, actually
you can leave it on Local and then spin around the Y axis (green)
eternal needle
oh does changing global-local setting in the scene view change what you see in t...
what you see in inspector is always local i believe
swift crag
same difference
sour fulcrum
what you see in inspector is always local i believe
yeah figured. was dealing with local vs world shit last couple days and would have been mad haha
a little toggle in the transform component would actually be kinda neat though
swift crag
```cs
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
```
Mathf.PingPong sounds useful here
Mathf.PingPong(Time.time * 45, 90)
this will go up to 90, then down to 0, then back up
moving at 45 per second
so, perhaps...
transform.rotation = Quaternion.AngleAxis(-45 + Mathf.PingPong(Time.time * 45, 90), Vector3.forward);
Oh, if only I knew that method existed before
swift crag
i've never actually used PingPong before
I do use Repeat sometimes
similar vibe, but it just goes up to the limit and then snaps back to 0
You could also do this
Mathf.Lerp(-45, 45, Mathf.PingPong(Time.time, 1));
90 degrees per second, between -45 and 45
sharp bloom
Oh, if only I knew that method existed before
I could have replaced this with that... (rotation speed that goes up and down)
timber tide
Ya making like a touhou game?
sharp bloom
Yes xd
timber tide
I remember someone doing the projectiles via animator. Looked pretty legit.
Mostly because there's some real tricky designs for some projectile waves.
Oh hey toonic was doing it
sharp bloom
I'm not really too interesting of using too much trigonometry and such to create the bullet waves
I just have "spawners" that spin and move in interesting ways
And spew out bullets in various rates
timber tide
Yeah, I've made some controller purely out of trig functions and stuff. It's very possible to create a unique system of bullets once you start pasting it all together.
mix in with spawners and such
Only problem though is it's a little harder to control compared to something like the animator. Not that touhou was ever fair ;)
sharp bloom
https://www.youtube.com/watch?v=GDs3QEbV_l0 I want to create something like this guy made in GameMakerStudio
timber tide
You've also got stuff like animation curves if you want to say slow down or accelerate over a lifetime
or even reverse the projectile entirely midway
makign curves with angular velocity
Pretty useful. You can throw them on like SOs and play around with the curve
I guess technically it's a mini animator ^^
but any value over time
swift crag
i wouldn't call it an animator
timber tide
you can grab that value right from it
swift crag
it just lets you define a curve and then evaluate it at any time you want
definitely useful, though (although the curve editor is...dated)
I always miss Blender's curve editing.
timber tide
Yeah, true it's just a curve. It is called animationCurve though so I'm just going with it haha

To have a timer wo shen it reaches 0 it resets the level

I'm trying for this code to instantiate a missile (thing that actually happens) and make it move towards the player. The thing is that the missiles spawn as they should, always looking at the player, but never move. In this picture, the player is the red capsule, the enemy, is the cyan capsule. The firepoint is a cube in the rocket launcher.

What is the programmatic way to disable an object, the effect that I would get if I checked or unchecked the object in the inspector?

green copper
Thank you
zealous geode
I'm still learning so I might not be sure at all.

you could add an OnDestroy method to the missile

delay is getting subtracted every frame, but nothing checks delay
and nothing calls MyFunction
formal escarp
ooohh
swift crag
you need to slow down and go through your code line by line
zealous geode
this could tell the missile shooting component about its destruction
To do this I need to create a script with the OnDestroy() call and place it inside the missile prefab right?
Because right now I did this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class missileControl : MonoBehaviour
{
private GameObject enemy;
private EnemyShoot fireScript;
// Start is called before the first frame update
void Start()
{
enemy = GameObject.Find("Enemy");
fireScript = (EnemyShoot)enemy.GetComponent(typeof(EnemyShoot));
}
// Update is called once per frame
void Update()
{
}
private void OnDestroy()
{
fireScript.missileFired = false;
}
}
And i'm having this issue:
swift crag
And which line is that exception happening on?
zealous geode
Oh, clicking the error leads me to the line. Didn't know that. It's happening on this line:
missile.transform.Translate(Vector3.forward * missileSpeed * Time.deltaTime);
Inside the EnemyShoot script.
swift crag
Yeah, the editor likes to take you to the second stack frame, instead of the top one, for some reason
swift crag
Oh, clicking the error leads me to the line. Didn't know that. It's happening on...
Is the missile control component not on the missile?
zealous geode
It is. Is a different script tho. That's why I called the EnemyShoot script on it.
swift crag
hm, okay
so, yeah, you'll want to give the missile a reference to the EnemyShoot script (perhaps assign it after instantiating the missile)
Actually, you know
you don't need to do that
you can just check if (missile == null)
or just if (missile) { ... }
When the missile object is destroyed, it will equal null, and it will evaluate to false
zealous geode
Ohhh, so I can just check it inside the EnemyShoot script, without having to create the control script, right?
Maybe I was doing things to difficult for something simple.
zealous geode
you can just check if `(missile == null)`
void Update()
{
player = GameObject.Find("Player");
PlayerMov playerscript = (PlayerMov)player.GetComponent(typeof(PlayerMov)); //Agarro el script del jugador.
reachIM1 = playerscript.IM1_On;
transform.LookAt(player.transform);
if (missileFired == false)
{
missilespawn = firepoint.transform.position;
missile = Instantiate(missileModel, missilespawn, Quaternion.identity);
missile.transform.LookAt(player.transform);
missileFired = true;
}
if (missile == null)
{
missileFired = false;
}
Debug.Log(missileFired);
missile.transform.Translate(Vector3.forward * missileSpeed * Time.deltaTime);
Destroy(missile, 7);
}
It works! Thank you so much Fen.
swift crag
Personally, I would make each missile do its own guidance
That would let you have many missiles at once, in case you decide to let an enemy fire more than one at a time
zealous geode
There is more than one enemy in that stage so for now I find it ok to leave it as it is.

timerText.text = elapsed.ToString();
}
}
}
but i dont seem to be able to do so.
swift crag
for loops will run over and over until the condition is false
If you don't want every single loop to run instantly, you can use them in a coroutine.
IEnumerator CountDown() {
for (float remaining = 60f; remaining > 0f; remaining -= Time.deltaTime) {
timerText.text = remaining.ToString();
yield return null;
}
}
yielding from a coroutine will wait until the next frame
Alternatively, just do it in Update
formal escarp
no no code is fine now
it does not reset on every single frame. it resets at 60 seconds as intented.

no no code is fine now
Elapsed should be set to timespan

yes.
im just tired and barely reading the code at this point 💀 i think i should go to bed.

But Fen is right

you really must move slower and think about what each line is doing

if you just mash random variables together it won't work
otherwise you'll wind up trying to solve the problem three ways, with none of them working!

Well Im seeing 2d joints so I assume there is a rigidbody on the log and that it falls due to gravity until the joint stops it?
lethal depot
yes it does have a rigidbody but the gravity value is set to 0
do i remove it from the log ?
charred spoke
Well not if you want to use your joints and stuff. I dont know why you need them
Im not familiar with 2d physics sadly
lethal depot
no problem i'll try
charred spoke
I would suspect the wheel joint
Maybe it hangs on the suspensions
I think you are overcomplicating your problem
Do you just need a rotating log?
lethal depot
yeah actually its a tutorial and there is no specification on why this is happening and the code actually is really complicated
lethal depot
I would suspect the wheel joint
i think i might just use the simple rotation instead

That would be better imho

it does, it's called OnPointerUp: https://docs.unity3d.com/2018.3/Documentation/ScriptReference/UI.Selectable.OnPointerUp.html
queen adder
its onClick event is invoked when it is released
then what event happens when you press it?
equivalent to GetKeyDown
#📲┃ui-ux message this for context
winter cove
the behaviour you're looking for, specifying distinct actions for mouse inputs, is done through the callbacks I reference in the link above. OnClick does work for this case, but the Button will never fire once clicked, but only when released after a click instead. Check out the documentation link
queen adder
leme try them both
slender nymph
you can use an EventTrigger component or write a script for it that implements the relevant event system interfaces you would like to use
queen adder

that's definitely possible, yeah
winter cove
if you don't want to code anything then you use the EventTrigger, but do note that the EventTrigger consumes ALL of the events on the Selectable element at hand, which may have implications you won't want to deal with.
queen adder

whether that's serialized in the inspector is a different question, I think it's not. But you can wrap that in a scriptable object to work around that issue, if the use case allows for it.

winter cove

It's not because of the inspector, it's because of how Unity's serialization works. Unity serializes (aka saves and displays in the inspector) specific types and for good reason. Take a look at this for more info:
https://docs.unity3d.com/Manual/script-Serialization.html#SerializationRules
While a Vector3 is serializable on its own, when wrapped inside a Unity Event it cannot be serialized, because Unity Events have specific serialization rules too. They can only serialize primitive types and types of Unity.Object
queen adder
inheriting from button doesnt show my extra fields 🥹 It's visible in debug inspector though
slender nymph
probably due to a custom inspector
queen adder
anywway, the fields in the debug mode is edittable (ig)
i can put things in, just not sure if it gets saved
using UnityEngine;
using UnityEngine.UI;
public class ButtonController : Button
{
public Transform Text;
public Vector3 OriginalLocalPosition;
public Vector3 PressedLocalPosition;
void Update()
{
Text.localPosition = IsPressed() ? PressedLocalPosition : OriginalLocalPosition;
}
}
```Working now without bug, just not sure how inefficient to use update just for something like thisAlso this IsPressed really should be a public method
not a protected
slender nymph
why even bother inheriting from Button when you can just create a regular monobehaviour that implements the IPointerDownHandler and IPointerUpHandler interfaces? then you won't even need to use Update at all, just the methods from the interfaces
and you won't have Button's custom inspector hiding your own serialized fields

Why can't i get this to work, im getting a null reference.
private float startHealth = 100f;
public TextMeshProUGUI healthText;
Awake() {
healthText.text = startHealth.ToString();
}
And the healthText is referenced in the inspector to my simple UI Text element.
gaunt ice
Show the inspector before and after play mode
gaunt ice
Put debug.log to see if the reference null, maybe duplicate script
summer hound
Im doing this
// Make sure healthText is not null before trying to access its text property.
if (healthText != null)
{
healthText.text = startHealth.ToString();
}
else
{
Debug.LogError("healthText is not assigned in the Inspector!");
}
And yepp, im getting the logerror.
By duplicate script, what do you mean?
ruby elk
If the code is on the same gameObject as the code, use this.gameObject.GetComponent<TextMeshProUGUI>().text = startHealth.ToString();
gaunt ice
Dont use get component if you can assign it…
ruby elk
Thats just what I personally use. May be slightly slower

The textvariable is public, so im just assigning it in the inspector

How would I create a list of recipes to check it against? Should I create a 2D array of strings with the item names cooresponding to the recipe and put the gameobject names into a list and check against all the recipes or can I use another way?

for some reason the Move thing isnt there in the player input thing here
also i had to copy this from online as i dont get how the new input system works and i dont wanna use old one
slender nymph
you have to hover over PlayerMovement there to see it
slender nymph
yeah well you didn't make that clear
you're also conveniently cutting off the rest of the event's info so i can't even say for sure if you have the correct parameter type
bitter carbon
wheres that
slender nymph
literally just outside the bounds of your screenshot
bitter carbon
slender nymph
it would be here
bitter carbon
slender nymph
but you can also just screenshot the entire component. you don't have to crop your screenshots to give as little info as possible
slender nymph
not only does that event take a different parameter, but you're subscribing to the wrong one. you presumably want to be subscribing to the one for your movement input which will likely be in that Player foldout
bitter carbon
so what do i need to change?
slender nymph
you need to click the - button below where it says No Function to unsubscribe from that event. then click the arrow next to Player to unfold that and subscribe to the correct event instead of the Device Lost Event which is certainly not going to be the one that is invoked for your movement input
bitter carbon
ok thanks
idk if it works yet but at least it shows the thing
lerts goo it works
ty, i wish the tutorial actually said

presumably the tutorial told you which event to subscribe to

Check the script that you have linked to it, then fix which script is connected
bitter carbon
the log i added shows up perfectly fine

great! now you know the issue is with the logic rather than with getting the input
bitter carbon
i think is because the player isnt tocuhing the ground because for some reason ,y player is floating instead of having gracity
gravity
and i have a rigid body thing
slender nymph
in that case you need to check that you've set up your Physics2D.OverlapCircle check correctly
bitter carbon
well i need it so i fall down
slender nymph
so start by looking at the layer(s) you have selected for your layer mask, make sure that your ground objects have that layer assigned to them
slender nymph

i didn't say remove it
you need to check that it works as you expect

this appears to be the layer selection on a game object, not the layer mask you are using for your overlap circle

i want it to be a bit different every time

which detects it
ty for your help
eventuallyt ill need to switch the jump with a teleport feature anwyay but i needed it like this for now to test
slender nymph
that is just the point that the OverlapCircle uses. that empty object is not the actual ground check. the overlap circle call inside of your IsGrounded method is what actually checks for ground. hence why i was focusing on that for troubleshooting your issue

Basically, C# classes don't attach to GameObjects, except for MonoBehaviours which is what sets up the whole attachment capability. As a rule, you are barred from accessing constructors on any components, so if your script doesn't inherit from MonoBehaviour, it won't interact with GameObjects. You probably need to have another MonoBehaviour reference your script and execute it.

What is the best way to avoid "Jittering" when two objects collide, say its two GAmeobjects that the player can "Click to move", so they walk towards the clicked position. If they both walk to the same position, they will start "Jittering" and spasm out
timber tide
Add some logic to check if multiple things are occupying a space and stop
silk night
itemCenter is a Vector2
A vector2 has 2 values, what are you trying to add it to?
timber tide
It's more that vector operators sometimes need to be written out
silk night
Either add new Vector2(0.1f, 0.1f); or what are you trying to do?
timber tide
try vec2 = vec2* double
silk night
oh wait
dawn sparrow
whatevers goin on with that
silk night
saw a + for some reason, yeah always use float with vectors in unity 😄
timber tide
I think there's just no operator overloads for some stuff
so you gotta just use what's there
it makes sense kinda with rotations though cause the precedence of multiplication matters
gaunt ice
it says that there is no overload version of * operator to handle vec2*double
silk night
Cause the internals of Vector2 are also floats, I think you generally cant do float*double in c# without any conversion
gaunt ice
it return double by default
silk night
it return double by default
System.Numerics or Unity Vector2?
gaunt ice
float*double
silk night
Ohh thats what you mean

How would i be able to make so the colors switch randomly like in geometry dash. Ive got it to choose random colors but im not sure how to smooth it out so it goes from another color to another smoothly. https://pastebin.com/w9jDkEeJ

Thank you

https://docs.unity3d.com/ScriptReference/Color.Lerp.html
is float t in sec or ms?
languid spire
is float t in sec or ms?
neither
languid spire
it's what you want it to be
float t=0;
while (t <= 1) {
t+= 0.1f;
color = Color.Lerp(orig, end, t)
yield return null;
}
in this example t 0.1 == time.deltaTime.
so it can be any time span you implement
languid spire
no, if you pass 1 then the result is always color
you need to vary t between 0 and 1 to change smoothly
languid spire

Hello. How can i make it so a visible timer appears and works? i can add text to my game but it stays still. I already have code so when timer hits 0 it resets the game.
using System.Collections;

elapsed += Time.deltaTime;
if (elapsed >= timeSpan)
{
elapsed = 0;
timerText.text = "00:00:00";
}
else
{
string text = formatTime(elapsed);
timerText.text = text;
}
}
private static string formatTime(float elapsed)
{
int hours = (int)(elapsed / 3600);
int minutes = (int)((elapsed % 3600) / 60);
int seconds = (int)(elapsed % 60);
return $"{hours:D2}:{minutes:D2}:{seconds:D2}";
}
}
not sure what to do, tried to watch some tutorials but they dont seem to work.
gaunt ice
the text doesnt change?
formal escarp
the text doesnt change?
Nope.
gaunt ice
text is not textmeshprougui

its a .ui right
gaunt ice
btw your timer is counting up
formal escarp
is counting up what
gaunt ice
textmeshpXXXX is under tmpro namespace
gaunt ice
no, i think your timer is counting up but it will suddenly becom 00:00:00 (reach timespan), will be little bit strange
formal escarp
but i dont want timer to go up i want timer to go down.
gaunt ice
change your text to textmeshprougui first then see the effect
gaunt ice
then your start time should be timespan then -=deltaTime in each update and stops when start time <=0
no, the type of timerText

i think i did it.
let me try it and show it to you

Oh, okay. And that's the only difference? Even if I use the latter method I am going to multiply it by screen size anyway to find point on the screen, right? 
swift crag
if you need a screen-space point, use WorldToScreenPoint
and yes, they are very similar

for example, logging the object you're hitting, along with its layer and the layer mask you're calculating

okay, so nothing is happening at all

If you don't have a log statement as the very first line, you are not testing if the collision is happening at all

If you move the object with Transform, the rigidbody isn't going to detect any collisions
You have to move it with the rigidbody

that would mean that the object isnt being detected on the proper layer but it definitely is on the right layer

damn the mods are on their A game. They came before the incantation was complete
swift crag
Ah, this is 2D!
You probably want aimTransform.up, then.
In a 2D game, the Z axis points into the screen
and forward is the local Z axis of the object
buoyant knot
2D has XY being the plane of the screen
swift crag
It probably also points into the screen. Not very useful.
Select the aim transform in the scene view and make sure you're in pivot + local mode. Look at the arrows.
red - right - X
green - up - Y
blue - forward - Z
If the green arrow points in the direction the bullet should go, use aimTransform.up
right, up, and forward will give you vectors in the direction of the red, green, and blue arrows
golden ermine
and `forward` is the local Z axis of the object
i tried that with up and bullets shoot randomly and not where mouse is and they dont start from the end of my gun

i tried doing this and having a if isColliding return; on update but it stil isnt working, should i go about it a different way?

Your wait coroutine is doing literally nothing
It does nothing, waits a few seconds, then does nothing
swift crag
StartCoroutine doesn't magically pause until the coroutine is over.
If it did, the entire game would freeze

my thought was to wait a few frames for the force and then start using the update method again

You need to reset isColliding inside the coroutine

You need to reset `isColliding` **inside the coroutine**
how

just did that, it works now, thanks!
swift crag
It's important to understand why the original code didn't work
polar acorn
Those red lines show this condition is never true:
if (4 <= dis && dis <= 20)
StartCoroutine takes an enumerator and tells your MonoBehaviour that it should be used as a coroutine
The MonoBehaviour will ask the enumerator for its next value every frame (by default)
That's all StartCoroutine does
So it won't "pause" anything until the coroutine is over. Its job is over
swift crag
The `MonoBehaviour` will ask the enumerator for its next value every frame (by d...
you can yield various objects to control this behavior, like a WaitForSeconds

If you want to check if a raycast hit something, wrap it in an if
if (Physics.Raycast...)
stiff peak
I'll look a little more into it but i think i get why it didn't work, i thought it was overwriting the script while working or something like that, i really appreciate the info thanks for clearing it up
polar acorn

Also, why are you raycasting, then moving the sphere before drawing the green or red line? Why would you not want to see the actual ray that was cast
The red and green lines have nothing to do with the original raycast

and if the issue is the raycast we don't need to see every script in your project

I fixed the indentation because the other one is a nightmare to read
https://gdl.space/evolajaxef.cs
You're using a lot of raycasts but you're never checking if any of them hit anything
If you don't care if the raycast hits anything, why raycast at all?
And when drawing the rays, you should include distance. Use dir * distance for the DrawRays
swift crag
You must check if a raycast succeeded.
If you don't, you could be using a RaycastHit with bogus data in it

Right before physics simulation, do all forces just get converted into velocity following f = ma, and a = v deltaT?
I guess, what is the difference when you AddForce vs AddForceImpulse? Does it just do the mass division for you later?

Yes, it's just throwing in some extra factors for you

hey can i get some help plz im trying to prevent spawn overlap but since theres no loop in the code it doesn't spawn the correct amount of objects. i have tried a couple of loops but each type freezes the game. im obviously doing something wrong here
private void SpawnEnemy()
{
//Loop code here.
spawnPoint = spawnLocation.transform.position + new Vector3(Random.Range(spawnAreaSize.x, -spawnAreaSize.x) / spawnAreaGap,
Random.Range(spawnAreaSize.y, -spawnAreaSize.y) / spawnAreaGap,
Random.Range(spawnAreaSize.z, -spawnAreaSize.z) / spawnAreaGap);
if (!Physics.CheckSphere(spawnPoint, spawnCollisionCheckRadius))
{
Instantiate(enemiesToSpawn[0], spawnPoint, Quaternion.identity);
}
}
fair enough, i would try something like this where the loop condition would be played once object is spawned
private void SpawnEnemy()
{
int length = 0;
//Random Spawning System Here
for (int i = 0; i == 1;)
{
spawnPoint = spawnLocation.transform.position + new Vector3(Random.Range(spawnAreaSize.x, -spawnAreaSize.x) / spawnAreaGap,
Random.Range(spawnAreaSize.y, -spawnAreaSize.y) / spawnAreaGap,
Random.Range(spawnAreaSize.z, -spawnAreaSize.z) / spawnAreaGap);
if (!Physics.CheckSphere(spawnPoint, spawnCollisionCheckRadius))
{
Instantiate(enemiesToSpawn[0], spawnPoint, Quaternion.identity);
length++;
}
}
}
for (int i = 0; i == 1;) 🤔

I think a better thing to do would be to use something like a CheckSphere or some other kind of physics query to see if they're in the "detection range"

this is cool but I cant see it graphically using colliders would be great to be able to debug on the editor

my spawnpoints also (right before they try to spawn something) check the area the thing would be spawning in. If it finds solid colliders in a certain set of layers, it blocks the spawn
this is called spawn blocking, and is standard in games like mario

set velocity to 0 manually when you release the controls, if you want that though, you should not use force sim and instead do a kinematic controller.

sounds like you want intense drag when you aren't inputting a move
although, that would make you fall very slowly

how do you put colors in your code there ?

Vector3 horizontalMove = Vector3.ProjectOnPlane(rb.velocity, Vector3.up);
rb.AddForce(-horizontalMove, ForceMode.Acceleration);
This would accelerate you at -10 m/s^2 if you were moving at 10 m/s
