this gives the correct position since the reticle is 64*64 even with screen scaling

var screen_pos = reticle.get_global_transform_with_canvas().origin
var wantedpos = Vector2(screen_pos.x +32, screen_pos.y +32)

now i need to figure out the decal lookat code. decals are also not consistant in scaling, dont know whats causing it is this a bug ?

cybereality

You can multiply by the scale, that might work.

decal.position + decal.scale.x * 32

Assuming reticle is inheriting from control you could probably get it's rect_size and use the screen_pos.x + rect_size.x/2 for an example instead of hard coding to +32 pixels in case you want to make the reticle scalable in the options.

Though better might be to put the reticles origin at it's center so you won't need that addition in the code at all, it's position will then be at the center of the screen always.

decal.position + decal.scale.x * 32

are u talking about the instantiated impact decal or the reticle?

cybereality

The reticle code should already work with the code posted before. I was talking about an impact decal, but maybe I misunderstood what you were asking for.

nope u were right the reticle works fine even tho its hard coded. i will try your decal solution, tnx

DJM

i dont understand your code example

decal.position + decal.scale.x * 32

this is the current code

if result:
		var collider = result.collider
		var n = result.normal
		var p = result.position
		
		#this is a decal scene>
		var impact = impact_normal.instantiate()
		collider.add_child(impact)
		impact.global_transform.origin = p 
		impact.look_at_from_position(p, p - n, Vector3.UP)
		
		impact.rotation.z = deg2rad(random.randf_range(0.0,360.0))
		if collider is RigidDynamicBody3D:
			collider.apply_impulse( p - collider.transform.origin ,  self.global_transform.basis.z * force)

the "impact global transform" works correct the "lookat " however isn't working at all were do i put your code? it says invalid operands 'vector3' and 'float' in operator '+'

cybereality

If you want the impact to face the camera (parallel to the wall), then the second parameter should be p + n. In terms of the scale code, I am just posting pseudo code from my memory. It's a good idea to understand what types and classes are available and how they work. I'm just giving you the concepts. The correct code should look like this, but you want to be able to understand why.

decal.position + decal.scale * 32.0

DJM

i want the impact to face the up normal of the hit collider. changing p + n gives same results and yes, i dont understand the code u posted, i dont understand the concept thats true

DJM

im debugging whats actually happening when instancing a decal so i made a simple arrow model to place when the raycast hits

2things are happening, i cant figure it out: 1 no matter what lookat function i use the arrow gets placed the same way(seems like global coordinates) 2 the arrow gets scaling applied to it depending on the object it hit

func firebullet():
	
	var screen_pos = reticle.get_global_transform_with_canvas().origin
	
	var add = reticle.get_texture().get_size().x /2
	var wantedpos = Vector2(screen_pos.x +add, screen_pos.y +add)
	var camera = self
	var from = camera.project_ray_origin(wantedpos)
	var to = from + camera.project_ray_normal(wantedpos) * ray_length
	var space = get_world_3d().direct_space_state
	
	var phys = PhysicsRayQueryParameters3D.new()
	phys.from = from
	phys.to = to
	phys.collision_mask = 1
	var result = space.intersect_ray(phys)

	if result:
		var collider = result.collider
		var n = result.normal
		var p = result.position
		print(n)
		#this is a decal scene>
		var impact = impact_normal.instantiate()
		collider.add_child(impact)
		
		
		
		impact.global_transform.origin = p 
		impact.look_at_from_position(p,p + n, Vector3.UP)
		#impact.look_at(p , Vector3.UP)same result
		#impact.look_at(p , Vector3.RIGHT)same result why?

so what is actually going on? how do i point the arrow to the hit normal UP, and prevent the scaling?

I could very well be wrong but if I'm reading that right you are adding impact as a child of the node hit by raycast, meaning the impact is inheriting the parents scale which explains the scaling. Not sure about the orientation tho.

DJM

even if i add the impact to root scene, same scaling results

I don't see anything obviously wrong with the code, but I won't be able to help until I get back next week. Unless I have time tonight, I can try to see if I can connect my tablet to the Steam Deck somehow, cause I can't type on the virtual keyboard. But I might be free tonight, in which case I can take a drive and pick up a mouse and keyboard. I'll let you know.

no need to interrupt your trip for me man. i can wait, im beginning to think its a bug.

cybereality

No, don't worry. This stuff is fun for me. I went to Best Buy last night, just got everything working.

DJM

@cybereality are u back from miami? hope u had a nice trip. im still having the "hit normal" issue, do u know whats going on?

cybereality

@DJM yes, I just got back. I'll look into it today.

cybereality

I got it working, but I must have spent like 2 hours on it. I understand why you couldn't figure it out. The solution was easy, but not obvious.

arrow.look_at(result.position + result.normal + Vector3(0.001, 0.0, 0.0))

DJM

im not getting the correct result

if result:
		var collider = result.collider
		var n = result.normal
		var p = result.position
		#print(n)
		
		var impact = impact_normal.instantiate()
		collider.add_child(impact)
		
		
		
		impact.global_transform.origin = p 
		impact.look_at(p + n + Vector3(0.001, 0.0, 0.0))
