You forgot to pack your textures, so we can’t see them. Pack them by doing “File->Pack Data”.
Your game crashes blender for some reason. I don’t know why exactly, but I get a bunch of “image errors” and then a seg-fault. Could be related to the fact that you forgot to pack, but that never usually spawns errors such as these, so I think it could be something more. Link to a .blend with packed data, so that I (or anyone else) could test that theory. (it could be a Linux specific thing, but I doubt it).
Since your game crashes on my machine I couldn’t see your problem in action, but I looked at the logic setup, and I think I found a solution. -> Don’t move your “bullet” with a motion actuator, you should use that “add object” actuator to apply force. Also you should enable “local transformation” (that little “[L]” to the right of the forces), so that your bullet will “shoot” in the same direction regardless of tank rotation.
I got the same problem before and it might be because of the use of .png image file,
for me, when player in blender it dont crash but if we make a runtime file, then the runtime cant read the png, but instead of just not showing it it crashes
Hello i have found the problem!! When the empty object there is turning the “gun/ the thing on the top of the tank” isn´t parented to anything it is working just fine. But if i parent the object there is controling the turning to another object it doesn´t work.
My problem is now that i can´t get the thing on the top to drive with the tank, exept there is another way to parent. Or just something to get the thing on the top to follow the tank!!
