I am mucking around with my UI elements and stumbled across a weird bug. If the speed of my object (with bullet behav) is 0 and I change speed through an event - then object will only move to the left or right. If you set the speed on the object itself though (from the properties panel) it will move at any angle you like.
Maybe its by design i dont know, you just have to change the speed of the object itself from the properties menu to see what i mean.

The idea was that I was going to have UI elements sitting out of view and then slide them onto the interface by changing the speed from 0 to whatever. I can get around though by spawning the object (with its speed set) when I need it instead.
Ive added another example, this time its with the "every X seconds" action instead of "On start of layout". It works on the second time it clicks over (still goes to the right first though).
