It abstracts or adds, if the node requires it, "body_entered", "is_colliding", and "body_exited" signals into "enter_act", "inside_act", and "exit_act" signals, respectively. However, it communicates this to a specific-named "Reaction" node, meaning that one action has one reaction

by arkology11
Adds many premade 2D effects (such as noise, blur, emboss, zoom, custom shapes, etc.) to build-in VisualShader editor. You can find basic usage examples in the "addons/shaderV/examples" folder. Copy the contents of "addons/shaderV" into the same folder in your project. Custom visual shader nodes work the same way as standard visual shader nodes. As all shaders sources are .gdshaderinc files, it is also possible to use this plugin with usual text shaders.
