ok

#

@sleek hedge

sleek hedge Dec 3, 2022, 7:22 AM

#

So what's confusing now

sick inlet Dec 3, 2022, 7:22 AM

#

alright so basically the chunk has a different position right so I need the points to be only in that poisiton for every new chunk

#

basically it needs to be within the chunk

sleek hedge Dec 3, 2022, 7:23 AM

#

Yeah just add that chunk's position to the tree's position

#

Might need to subtract half of the size from it or something, I don't know where your terrain's pivot is

sick inlet Dec 3, 2022, 7:23 AM

#

sleek hedge Yeah just add that chunk's position to the tree's position

do i add it too here

sleek hedge Dec 3, 2022, 7:24 AM

#

sick inlet do i add it too here

No you can just add it to the var point you create in the loop

sick inlet Dec 3, 2022, 7:25 AM

#

like this?

#

cus the script is already attached to the mesh

sleek hedge Dec 3, 2022, 7:25 AM

#

transform.position.z not y

sick inlet Dec 3, 2022, 7:28 AM

#

@sleek hedge alright so the raycast didn't rly hit so it kinda just spawned in the same y coord

#

is it because im using mesh colliders or something

#

#

this is what it currently looks like

sleek hedge Dec 3, 2022, 7:29 AM

#

sick inlet

Don't remove the if check from the raycast

#

Actually just do

if (!Physics.Raycast(point, Vector3.down, out hit))
{
  coninue;
}

#

So that it skips that position if the ray didn't hit anything

sleek hedge Dec 3, 2022, 7:32 AM

#

sick inlet is it because im using mesh colliders or something

As long as your mesh colliders are the same shape as your terrain, its fine

sick inlet Dec 3, 2022, 7:32 AM

#

nothing spawned

#

only 1 cube at y 1000

sleek hedge Dec 3, 2022, 7:32 AM

#

sleek hedge Actually just do ```cs if (!Physics.Raycast(point, Vector3.down, out hit)) { c...

Did you do this?

sick inlet Dec 3, 2022, 7:33 AM

#

sleek hedge Dec 3, 2022, 7:33 AM

#

sick inlet

Now you aren't using hit.point anymore...

#

After the raycast check, do point.y = hit.point.y

sick inlet Dec 3, 2022, 7:34 AM

#

outside the if statement?

sleek hedge Dec 3, 2022, 7:35 AM

#

Yeah

#

Because if the code passes that if statement, you have a hit.

#

Otherwise you continue which means skip the current iteration of the loop

sick inlet Dec 3, 2022, 7:35 AM

#

alright it didn't spawn anything

#

sleek hedge Dec 3, 2022, 7:36 AM

#

Then transform.position is maybe not the correct pivot

#

You should debug the raycast

sick inlet Dec 3, 2022, 7:37 AM

#

shoudln't it still spawn tho?

#

alr

sleek hedge Dec 3, 2022, 7:37 AM

#

Debug.DrawRay(point, Vector3.down * 5000, Color.yellow, 10f);

#

Before the raycast.

sleek hedge Dec 3, 2022, 7:38 AM

#

sleek hedge ```Debug.DrawRay(point, Vector3.down * 5000, Color.yellow, 10f);```

I added the 10f so it stays 10 seconds @sick inlet

sick inlet Dec 3, 2022, 7:39 AM

#

holy fuck

sleek hedge Dec 3, 2022, 7:40 AM

#

Now you see your rays, it's up to you to fix the correct offsets etc.

sick inlet Dec 3, 2022, 7:40 AM

#

its still making a collison tho

#

so shouldn't it still spawn?

sleek hedge Dec 3, 2022, 7:40 AM

#

sick inlet its still making a collison tho

How do you know?

sick inlet Dec 3, 2022, 7:41 AM

#

sleek hedge How do you know?

the ray touchs the mesh with a collider on it

#

which is the condition for it to spawn

#

am i missing smth

#

lol

sleek hedge Dec 3, 2022, 7:43 AM

#

Alright lets make the ray debug a bit better.
Put this inside the if(!Physics.Raycast(... block:

Debug.DrawRay(point, Vector3.down * 5000f, Color.green, 10f); // Draw miss```
And after that block, outside of it:
```cs
Debug.DrawLine(point, hit.point, Color.red, 10f); // Draw hit```

#

And remove the previous Debug.DrawRay

sick inlet Dec 3, 2022, 7:45 AM

#

question abt here

#

sleek hedge Dec 3, 2022, 7:45 AM

#

Bruh, you didn't change that?

sick inlet Dec 3, 2022, 7:45 AM

#

wait

#

dang

#

im stupid

sleek hedge Dec 3, 2022, 7:46 AM

#

sleek hedge ``transform.position.z`` not y

......

sick inlet Dec 3, 2022, 7:46 AM

#

#

sorryyy

#

also now the pos for the lines are correct

#

but no red lines

#

so it didnt hit

sleek hedge Dec 3, 2022, 7:47 AM

#

If you rotate the view, are they actually going thru the mesh?

sick inlet Dec 3, 2022, 7:47 AM

#

they are

sleek hedge Dec 3, 2022, 7:47 AM

#

Does it have a proper mesh collider?

sick inlet Dec 3, 2022, 7:47 AM

#

sleek hedge Dec 3, 2022, 7:47 AM

#

Test if a normal rigidbody goes thru it or collides with it

sick inlet Dec 3, 2022, 7:47 AM

#

it does

#

the player collides

sleek hedge Dec 3, 2022, 7:49 AM

#

Can you screenshot your current code again?

sick inlet Dec 3, 2022, 7:49 AM

#

w

sleek hedge Dec 3, 2022, 7:50 AM

#

Not sure what's wrong yet, really

#

For starters, try changing the 1000 to something lower, maybe 100

#

You are almost done, but for some reason the raycast won't detect your mesh collider

#

Maybe it has too many vertices or something... don't know

sick inlet Dec 3, 2022, 7:52 AM

#

nothing

#

i tried changing it to 100

sleek hedge Dec 3, 2022, 7:53 AM

#

Your terrain is not on the Ignore Raycast layer is it? 😅

#

I need to go, already spent more than an hour here lol

sick inlet Dec 3, 2022, 7:55 AM

#

nope

sleek hedge Dec 3, 2022, 7:55 AM

#

Hope you find whats wrong or someone else can help

sick inlet Dec 3, 2022, 7:55 AM

#

ah no worries its fine

sleek hedge Dec 3, 2022, 7:55 AM

#

I can check it out later

sick inlet Dec 3, 2022, 7:55 AM

#

tysmm

#

for everything

sick inlet Dec 3, 2022, 8:21 AM

#

@sleek hedge if i changed my code like this

#

all the raycasts redirect to the same point

sleek hedge Dec 3, 2022, 8:24 AM

#

It was !Physics.Raycast and now you inverted it..

#

Just keep the !Physics.Raycast and continue there like it was before.

#

And put that if(hit.collider... check after the if(!Physics.Raycast... and continue

#

I don't know why you changed the structure so much and broke it completely

sick inlet Dec 3, 2022, 8:27 AM

#

sleek hedge I don't know why you changed the structure so much and broke it completely

i changed it back im just experimenting anything to see if i can get it to work

#

cus it detects for some reason when i don't invert it

sleek hedge Dec 3, 2022, 8:28 AM

#

Yeah that's fine, it's just that the logic there doesn't really make sense

#

Because you are currently drawing the misses if you hit 🤔

#

And drawing the hits if you didn't even hit.

#

(That's why they all point to the same position: because the default hit.point is zero)

sick inlet Dec 3, 2022, 8:29 AM

#

oh

#

welp

sick inlet Dec 3, 2022, 7:01 PM

#

@sleek hedge I did what you told me about the shared mesh but it still doesn't raycast

#

        this.coord = coord;
        this.detailLevels = detailLevels;
        this.colliderLODIndex = colliderLODIndex;
        this.heightMapSettings = heightMapSettings;
        this.meshSettings = meshSettings;
        this.viewer = viewer;

        sampleCentre = coord * meshSettings.meshWorldSize / meshSettings.meshScale;
        Vector2 position = coord * meshSettings.meshWorldSize ;
        bounds = new Bounds(position,Vector2.one * meshSettings.meshWorldSize );


        meshObject = new GameObject("Terrain Chunk");
        meshRenderer = meshObject.AddComponent<MeshRenderer>();
        meshFilter = meshObject.AddComponent<MeshFilter>();
        meshFilter.mesh = myNewMesh;
        meshCollider = meshObject.AddComponent<MeshCollider>();
        meshCollider.sharedMesh = myNewMesh;

        meshRenderer.material = material;
        treePos.Add(meshObject.transform.position);

        treeObject = new GameObject("Tree Chunk");
        meshTree = treeObject.AddComponent<TreeGen>();



        treeObject.transform.position = new Vector3(position.x, 10, position.y);
        meshObject.transform.position = new Vector3(position.x, 0,position.y);
        meshObject.transform.parent = parent;
        SetVisible(false);

        lodMeshes = new LODMesh[detailLevels.Length];
        for (int i = 0; i < detailLevels.Length; i++) {
            lodMeshes[i] = new LODMesh(detailLevels[i].lod);
            lodMeshes[i].updateCallback += UpdateTerrainChunk;
            if (i == colliderLODIndex) {
                lodMeshes[i].updateCallback += UpdateCollisionMesh;
            }
        }

        maxViewDst = detailLevels [detailLevels.Length - 1].visibleDstThreshold;

    }```
