Tangentially related: Oh boi I just love AI bros coming out of nowhere defending GenAI when nobody asked for their opinion. Wish more communities / instances would take a hard anti-AI stance and just get rid of them. It’s not like anyone will make them see where they’re wrong.
color_rect.set_instance_shader_parameter
should work, as long as thecolor_rect
is unique to each instance of the card, rather than being reused. If you assigned it in the node editor you could check the “Local To Scene” checkbox. Assuming cards are defined as separate scenes you instantiate. Otherwise you couldduplicate()
the resource in code.The same would be true for
color_rect.material.set_shader_parameter
for theShaderMaterial
. If you could ensure it’s unique per card, it should work. However, duplicating the material might not be as ideal, especially since the other option is also available.A little tip: You could try print debugging with the
get
functions before and after you useset
to see what the value was before (and notice that it might be the same as the previousset
call from another card) and that it was correctly set afterwards. (Assuming I’m correct about diagnosing the problem.)edit: Actually, my advice is only true if
color_rect
was a resource, but I think it’s a node, specifically a sub-class ofCanvasItem
orGeometryInstance3D
, so it should already be unique for each instantiated card. So without more information I’m not sure whyset_instance_shader_parameter
is not working.
