Hi there thanks for your reply.
I want the mesh to be replaced by pressing let’s say “r” key. What i did was placed object A in visible layer with the property int, value=1. In logic brick, placed a keyboard sensor which is the “r” key connected to AND controller, connected to replace mesh to object B which is in 3rd layer and i also connect (actuator)property “prop” value = prop+1
And for the second sensor I did property “prop” value =2 and the keyboard sensor “r”, connect in to AND controller and connect it to replace mesh to object C (which is in 4th layer). But the mesh isn’t replacing.
Basically, when i press the key"r" for the first time, the object A will replace with object B. If I press “r” again the replaced object (object B) will be replaced to object C. I’m not sure how to do it. I tried few other way but I was only managed to change 1 time only.
I’m using blender 2.49 by the way, thanks for looking into it.
