problem with collision and moveentity
Posted: Thu Oct 23, 2008 8:04 pm
Hi
I was playing with the example code SimpleCollision.pb and changed the
code to every time the robot is moved; plays the Walk animation and the Idle
animation when the robot stops.
It seems to work fine, but when I changed
the part of the collision code, to send the robot backwards when hit a cube,
It work when I call MessageRequester before, but if I comment out the
line MessageRequester("Collision Detected", "Collision in Z"), or the X one,
the MoveEntity don’t send the robot backward.
Somebody can help to correct this?
I’m still learning Purebasic, Ogre and English
By the way I’m using 4.3 beta 3 and a ogre1.6 example
Thanks
