Collision Detection for Hierarchies of Objects
Hey,
I'm having some trouble getting collision detection to work consistently with hierarchies of objects. I'll create a person and a ball with code like the following: person = viz.add("male.cfg") ball = person.add("ball.wrl") ball.collidesphere(0.25) After translating the ball to some location (using viz.ABSOLUTE_WORLD), I'll try to translate the person (also using viz.ABSOLUTE_WORLD), and the ball moves with the person as expected. But the problem is that the "collidingwith()" method thinks that the ball is still where I positioned it originally. As far as the collidingwith() method is concerned, the ball did not move with the person... Is there any way to fix this problem? -Josh |
Hi,
The collidingwith function does not take object hierarchies into account. You can use a temporary work around for this though. Add an empty object to the world. To check for collisions update the empty objects position with the balls position and then call collidingwith on the empty object. Here's some sample code to explain it better: Code:
#Add a fake ball to the world (This will be an empty object) |
