Changing shaders in a game during runtime
So the basic idea I want in my game is any "Environment" object in the way between the player and the camera to change to a transparent shader so you can see the player. I have the raycast correctly calculating the buildings. I also want to revert back to the original shader once the raycast is not touching the object anymore. I have a shader that makes objects transparent, however once I apply the shader to the Environment object it turns pink and I am unsure why.
Here's the code I have so far in my FixedUpdate function:
ray = Camera.main.ScreenPointToRay(Input.mousePosition);
Vector3 fwd = transform.TransformDirection(Vector3.forward);
Debug.DrawRay(transform.position, Vector3.forward);
if (Physics.Raycast(transform.position, fwd, out hit))
{
if (hit.collider.gameObject.tag == "Environment")
{
Transform objectHit = hit.transform;
objectHit.GetComponent<Renderer>().material.shader = Shader.Find("ToonLitOutlineTransparent");
Debug.Log("Building has been hit");
}
}
I am unsure how to solve this problem and any help would be appreciated.
EDIT: Just an FYI when i drag the shader through in my scene view, it works fine. It just turns pink at runtime so I assume there is a conflicting error.
Pink color shows a shader compile error. A good way might be to change material ins$$anonymous$$d of just the shader.
So ins$$anonymous$$d of calling the shader, create a material with the shader on and use that?
If its pink in build, that could mean shader is not included in the build. Can assign it to Always included shaders from Edit/Project Settings/Graphics other ways of always including it: https://docs.unity3d.com/ScriptReference/Shader.Find.html
Otherwise could also check if the Shader.Find returns null.
