Hi,
I'm not sure what exactly you're trying to do because using "on activate of" on the camera object itself isn't going to work. You're are viewing the scene from the camera object, therefore you can use the "on activate of" event on other objects in the scene like this:

If you want to move the camera using Blockly you can just enable it for Blockly, set it to "Fly" mode and use the "move" block to move it.



This way you also can move the camera when you're clicking on another object.
