Box collision

Troubleshooting physics

hey guys



sorry if my question is stupid or something like that but im new to jME and really dont know all options the engine provides me ^^.



so i have the problem that i have a sphere that i shoot and i want to handle collision with a wall (its a big box).

so i cant use the world bound, because in fact its kinda too huge :smiley: and i dont really know what the model bound is and how to handle with it however model bound didnt work.

i used the intersects method.



is there any simple sollution? im shure there is one ^^



so far

well intersection sounds right, where is the problem with that?

yes intersect works fine but i dont know on what to check intersection. as i explained i cant use the world bound. so i somehow need the normals or something like that…just dont know ^^

There is no world-bound without modelbound. that means you should do something like this:


Box wall =....
wall.setModelBound(new BoundingBox());
wall.updateModelBound();
wall.updateWorldBound();
Box player =....


(same as wall)
check with :

if(player.hasCollision(box,false=boundingcollision/true=trianglecollision))
{...}
