Edge of Radius | Official Unity Discord | Page 1

I have this script where the player can shoot a ball, if the player clicks outside max shoot radius the point should just be at the edge. I am not sure how to make it be at the edge of that radius

This shoot radius, is it a circle? @fickle pike

plucky dust This shoot radius, is it a circle? <@531176619398922250>

Well currently if you shoot inside the radius it will just place a debug ball in that location, but if you click outside the radius I want to find the closest point to the edge of the radius and place the ball there'

Is it a circle?

#

Post full scripts in a pastebin link
https://gdl.space

#

Since you are speaking of Radius one might assume it is a circle, but since I have no idea, and for the sake of not working with false assumptions, is it?

fickle pike Oct 1, 2022, 5:52 PM

#

I would like it to be a circle yes. This is the whole script for now, some stuff is not used and other is just for debugging

Are you 100% here now?

fickle pike Oct 1, 2022, 5:53 PM

#

Im here yeah?

plucky dust Oct 1, 2022, 5:53 PM

#

Great. I hit many dead ends lately, and I dont' have time to wait for people. Anyway

fickle pike Oct 1, 2022, 5:54 PM

#

Ah makes sense

plucky dust Oct 1, 2022, 5:54 PM

#

Does this circle exist yet in any way?

fickle pike Oct 1, 2022, 5:55 PM

#

Well it only exists when checking if the hit.point is outside the maxAtkDist float

#

Else there is no gameobject or anything else

plucky dust Oct 1, 2022, 5:56 PM

#

is this 2D or 3D?

fickle pike Oct 1, 2022, 5:56 PM

#

3D

plucky dust Oct 1, 2022, 5:57 PM

#

kk, trying to visualize
Anyway, my initial thought is the following

#

I'm just not sure it will work in 3D

fickle pike Oct 1, 2022, 5:57 PM

#

I can like paint a small pic of what im trying to do to further explain

plucky dust Oct 1, 2022, 5:57 PM

#

A screenshot of the scene could help

plucky dust Oct 1, 2022, 6:02 PM

#

When the mouse button is clicked,
the raycast is performed,
and if something is hit,
then the object should be spawned at position:

fickle pike Oct 1, 2022, 6:04 PM

#

Well

plucky dust Oct 1, 2022, 6:04 PM

#

(I'm typing code)

fickle pike Oct 1, 2022, 6:05 PM

#

ah ok

plucky dust Oct 1, 2022, 6:09 PM

#

float distance = Vector3.Distance(transform.position, hit.point);
float spawnDistance = distance;
if (distance > maxAtkDist) 
{
    float overshoot = (distance - maxAtkDist)
    spawnDistance -= overshoot;
}
executeAttack()

#

need to google some Vector logic

#

code is unfinished, but you get the gist of it

#

Notice how I split up the formula inside the if-statment. That's for being able to read the logic, without understanding the full formula

fickle pike Oct 1, 2022, 6:10 PM

#

Oh wait, thats what I did, but forgot to set the new position

#

Thanks :D

plucky dust Oct 1, 2022, 6:11 PM

#

That's what I was about to google how to calculate

#

really hazy this Saturday xD

#

If that solves it, good stuff. Let me know once that's done, or if you need help with the last bit.

fickle pike Oct 1, 2022, 6:11 PM

#

Sure, just need to clean some cloths real quick

plucky dust Oct 1, 2022, 6:12 PM

#

changed the Vector3s to floats, because d'uh

fickle pike Oct 1, 2022, 6:22 PM

#

Ight im back and going to try it now

#

Changin them to floats won't work though, I only care about the X and Z axis and the executeAttack function requires a vec3 to change the position of the debugOBJ

#

This is what I got with trying another way

#

This is the new script ```cs
void onPlayerAttack(InputAction.CallbackContext ctx)
{
Ray ray = cam.ScreenPointToRay(pManager.mousePos());

    if (Physics.Raycast(ray, out hit))
    {
        float distance = Vector3.Distance(transform.position, hit.point);
        if (distance > maxAtkDist)
        {
            // Get point on hit.point direction closest to sphere radius (maxAtkDist)
            float overShoot = (distance - maxAtkDist);
            Vector3 newPos = new Vector3(hit.point.x - overShoot, hit.point.y, hit.point.z - overShoot);
            executeAttack(newPos);
        }
        else
            executeAttack(hit.point);
    }
}

void executeAttack(Vector3 hitPoint)
{
    debugOBJ = GameObject.CreatePrimitive(PrimitiveType.Sphere);
    debugOBJ.transform.position = hitPoint;
}```

#

For some reason that makes it spawn in 3 random positions

#

This is what I have been kinda thinking but I hoped there was a function in the Mathf library that could just get me the closest point to the radius

#

@plucky dust

plucky dust Oct 1, 2022, 6:56 PM

#

Reading

#

newPos is wrong

fickle pike Oct 1, 2022, 6:57 PM

#

what should newPos be then?

plucky dust Oct 1, 2022, 7:02 PM

#

Checking that atm

Vector3 direction = destination - origin;

fickle pike Oct 1, 2022, 7:05 PM

#

I knew how to get the direction, i just don't fully know how to get the right position

plucky dust Oct 1, 2022, 7:05 PM

#

it's a tough google tbh

fickle pike Oct 1, 2022, 7:05 PM

#

Yeah thats why i came here lol, I didn't know what to google

plucky dust Oct 1, 2022, 7:07 PM

#

Vector3 origin = transform.position;
Vector3 direction = new Vector3(1,1,0);
float distance = 0.5f;
Vector3 destination = origin + (direction * distance);

#

you need to modify direction

#

Vector3 direction = destination - origin;

plucky dust Oct 1, 2022, 7:08 PM

#

fickle pike Yeah thats why i came here lol, I didn't know what to google

A good use of time would be to find a basic Vector math tutorial that probably contains the answer.

fickle pike Oct 1, 2022, 7:09 PM

#

So this?

Vector3 Direction = transform.position - hit.point;
Vector3 destination = transform.position + (Direction * maxAtkDist);```

destination - origin

fickle pike Oct 1, 2022, 7:09 PM

#

oh ok

plucky dust Oct 1, 2022, 7:09 PM

#

it's a tricky formula ^^

#

but simple

fickle pike Oct 1, 2022, 7:10 PM

#

Yeah, I guess i have mixed them this whole time them lol. Ill go for google and let you free now lol

plucky dust Oct 1, 2022, 7:10 PM

#

fickle pike So this? ```cs Vector3 Direction = transform.position - hit.point; Vector3 desti...

I believe this is wrong, sec.

#

float distance = Vector3.Distance(transform.position, hit.point);
float spawnDistance = distance;
if (distance > maxAtkDist) 
{
    float overshoot = (distance - maxAtkDist)
    spawnDistance -= overshoot;
}
executeAttack()

#

float distance = Vector3.Distance(transform.position, hit.point);
float spawnDistance = distance;
if (distance > maxAtkDist) 
{
    float overshoot = (distance - maxAtkDist)
    spawnDistance -= overshoot;
}
Vector3 direction = (hit.point - transform.position).normalized;
Vector3 destination = transform.position + (direction * spawnDistance)
executeAttack(destination)

#

I think that's final, if you can implement that in your code.

fickle pike Oct 1, 2022, 7:13 PM

#

Alright Thanks so much :D

plucky dust Oct 1, 2022, 7:14 PM

You're welcome. Good luck, and have a nice weekend 👋

Is answers.unity.com a dead site?

plucky dust Oct 1, 2022, 8:38 PM

#

fickle pike Is answers.unity.com a dead site?

No, I was just on it. Probably just network issues somewhere.

#

I haven't actually run this code, but here is a polished version

private Vector3 NewPos(Vector3 origin, Vector3 destination, float maxDistance = 0f)
{
    float distance = Vector3.Distance(destination, origin);
    float clampedDistance = distance;

    bool maxDistanceIsRelevant = maxDistance > 0f;
    bool distanceIsHigherThanMax = distance > maxDistance;

    if (maxDistanceIsRelevant && distanceIsHigherThanMax)
    {
        float overflow = (distance - maxDistance);
        clampedDistance -= overflow;
    }

    Vector3 direction = (destination - origin).normalized;
    Vector3 clampedDestination = origin + (direction * clampedDistance);

    return clampedDestination;
}

#

@fickle pike There was one error in the solution I gave you.

// Wrong.
Vector3 direction = destination - origin;
// Correct. 
Vector3 direction = (destination - origin).normalized;

#

Corrected the last two script segments here.

fickle pike Oct 1, 2022, 9:18 PM

#

Ah ok thanks, and with the answers.unity.com I haven't been able to get on the last two weeks. I have been on many different networks thees two weeks so its kinda weird if they all had problems with that one site

plucky dust Oct 1, 2022, 9:20 PM

#

That's odd. Are you still not able to load the site?

fickle pike Oct 1, 2022, 9:20 PM

#

nope

plucky dust Oct 1, 2022, 9:23 PM

~~may I ask which country or continent you're on?~~

actually, nevermind

it will only lead to speculation

It should be fine in denmark

plucky dust Oct 1, 2022, 9:25 PM

Hm. Using custom DNS or anything?

fickle pike Oct 1, 2022, 9:25 PM

Nope all stock to keep it easy for my parents

if you're on Windows you can open cmd and type tracert learn.unity.com to see where it stops in the chain.

fickle pike Oct 1, 2022, 9:27 PM

might be the equivalent

not on an arch based distro

plucky dust Oct 1, 2022, 9:28 PM

Have you restarted your computer these past weeks?

is this a laptop?

fickle pike Oct 1, 2022, 9:29 PM

I haven't used this one the past 6 weeks doe to me living on a school, its a concept really hard to explain because its not found outside denmark

But it also doesn't load on my laptop

Folkhighschool?

#

If you've been on 4 networks with the same Arch Linux installation, perhaps there is something missing in Linux.

#

if that was the case

fickle pike Oct 1, 2022, 9:32 PM

#

plucky dust Folkhighschool?

Efterskole is the danish name for it but from what I know it doesn't translate that well

plucky dust Oct 1, 2022, 9:32 PM

kk

fickle pike Oct 1, 2022, 9:35 PM

google.com vs answers.unity.com

plucky dust Oct 1, 2022, 9:36 PM

#

it doesn't even leave your computer?

#

That's odd. And this is spiraling into very off-topic.
But for the sake of testing your arch build for flaws, keep a Live USB of some distro that just works with everything, so that you can quickly see if the Live version can achieve things your Arch installation cannot.

fickle pike Oct 1, 2022, 9:38 PM

#

Im sure I can fix it at some point

#

anyways the code you sent was a little cleaner than what I made, but both works

#

Thanks again :D

plucky dust Oct 1, 2022, 10:03 PM

fickle pike Thanks again :D

Good stuff. Have a nice evening 👍

fickle pike Oct 1, 2022, 10:04 PM

you too

plucky dust Oct 1, 2022, 10:14 PM

PS:

private Vector3 NewPos(Vector3 origin, Vector3 destination, float maxDistance = 0f)
//  = 0f
// Doesn't make sense in this context, as you'd never want to ignore that parameter. Remove.
private Vector3 NewPos(Vector3 origin, Vector3 destination, float maxDistance)
