Resolved Can't get Camera point to ray in Tiny

Correct you can't use ScreenPointToRay from the classic Unity
You can either
Check our RuntimeGeometry3D sample we do use ScreenToWorld system
https://github.com/Unity-Technologi...ometry3D/Assets/Scripts/GeometryMainSystem.cs

Or use Raycast from Unity.Physics https://docs.unity3d.com/Packages/com.unity.physics@0.0/api/Unity.Physics.RaycastHit.html I think there is a sample in this project https://github.com/Unity-Technologies/EntityComponentSystemSamples/tree/master/UnityPhysicsSamples that uses physics raycasts

 

maybe do something like

Code (CSharp):

1. using Unity.Entities;
2. using Unity.Mathematics;
3. using Unity.Tiny.Input;
4. using Unity.Transforms;
5. using Unity.Tiny.Rendering;
6.  
7. public class MySystem : SystemBase
8.     {
9.         protected override void OnUpdate()
10.         {
11.             var input = World.GetExistingSystem<InputSystem>();
12.             var s2w = World.GetExistingSystem<ScreenToWorld>();
13.             var inputPos = input.GetInputPosition();
14.             float3 pos = s2w.InputPosToWorldSpacePos(inputPos, 4.0f);
15.             // Do whatever with pos
16.  
17.         }
18.     }

make sure to add
"Unity.Tiny.Input",
"Unity.Tiny.Rendering.Native",
"Unity.Tiny.Rendering",
to your asmdef references
