Here’s something a little odd. I’m using a Mac laptop and the Steam version of Godot (until the C# lectures start coming out). I have the trackpad setup so if I lightly tap the trackpad it is a left mouse button press. This causes the Godot event to trigger but doesn’t animate the button. When I push down on the trackpad so it clicks then the animation and the event trigger. I guess it’s a little bug in Godot…
