  • cannot call tween method on a null valueBrain Siege GameworksI have the method set_material_alpha and I have this line: `var current_alpha: float = MATERIAL_HIGHLIGHT.get_shader_parameter("alpha")` For some reason it's null. Not sure if it's the current alpha or the method. In theory it's the current_alpha though. The material overlay should be applied too. `_tween.tween_method(set_material_alpha, current_alpha, 1.0, 0.1)` 3 0 Apr. 03, 2025
  • Why the use of tool in the parent classiguessfiveFor the `Door3D` was it necessary to add a tool script the parent `Interactable3D` script as when adding a tool to the child class the parent class will also run in the editor. Asking to see if there is a performance cost involved by doing this? Another thing I noticed was the shader alpha parameter was set to 0 initially, in the resource file so after the section where we add the tool the code was not working as intended at that point in the lesson. 1 0 Mar. 31, 2025
