I did draw a toon outline but I wanted to it change its color to white when the ray cast collides, so it shows that the object can be selected

you should use a uniform variable.
For example:
uniform vec4 toon_outline : hint_color
remember to use hint_colour, because it will make setting shader params VERY EASY

You didn’t mention if you’re working in 2D or 3D, so I’ll assume 2D:
if $RayCast2D.is_colliding():
var collider = $RayCast2D.get_collider()
collider.material.set_shader_param("outline_color", Color(1., 1., 1., 1.))
That assumes your shader has a parameter outline_color
defined:
uniform vec4 outline_color
that you’re using to set the outlines color.
I am using 3d.

Alright, then it’s RayCast instead of RayCast2D - everything else stays the same.

i am getting this error:
Invalid get index ‘material’ (on base: ‘StaticBody’).
if ray.is_colliding():
var interact = ray.get_collider()
interact.material.set_shader_param("albedo", Color(255, 0, 0, 0))
i tried outline_color (created the uniform and changed ALBEDO = albedo.rgb) but also get the same error
my outline is in the next pass as a shader. just wanted to change its color of black to white in the runtime

That means the node your RayCast is colliding with (the collider you save into the variable interact
) is a StaticBody. Which (unlike it’s 2D-counterpart StaticBody2D) does not have the material
-property you’re trying to access.
So you need to adapt the path to your scene tree and the location of your shader material. If it’s on a direct MeshInstance-child of interact
it would be:
interact.get_node("MeshInstance").mesh.material
