I recently began experimenting with BGE (Blender Game Engine).
I’ve got a basic character, with a child containing the actual model (the top level character is simply a hidden physics body shape).
The top level character contains all my sensors, controllers and actuators for movement, looking around, etc.
I reopened blender this morning and found that I can no longer add logic bricks to my top level character.
On the “add” menu, every item from each of the options (sensor etc) is greyed out, so does nothing when clicked. I can delete existing bricks, I can disconnect and reconnect things, and the bricks themselves still work, but I cannot add any new bricks.
This is specific to this node, I can add scripts on other nodes, but not the top level character, or sub nodes of the top level character.
