I want to create a object that appears when i'm pressing left ctrl! but addobject actuator don't work:
Firstly i created a plane then i created a object named "sphere"
i linked sensor keyboard (key left ctrl) from this object to the controller andthen to the actuator edit object -> add object Object to add is named "sphere". (OB:sphere)

But when i'm running the game and pressing left ctrl nothing appears.
Please help!!!
I'm from Poland, I'm not good in English, sorry![/i]

Is the sphere on the same layer as the plane? If so, this is the problem.
Try moving the sphere to layer 2 (MKEY) and start your game again with layer one (where the plane is) active.

Hope that helps
