How can I detect which model give/got the collision?

[CuecaX]

I want to know which model is colliding with the other model and the point that it hits.

how can i do this?

thanks in advance

if you use newton physics engine then object whitch collide calls a newton callback, in the callback you can also write what to do for a model when it collide. about geting a point of collision i dont know, havent tried

Yup, Irrlicht's collision detection is very basic and doesn't support collision between scene nodes in this manner, at least that I know of. I mentioned in another post. Here is a linky. http://irrlicht.sourceforge.net/phpBB2/ ... highlight=

doesnt irrlicht has at last some function to return the name of scene node is coliding with the other? the exact point doesnt matter to much...


i need to check if the player is hitting a cube from underneath (its a "?" mario-like block)
and what block is the player hitting (the bricks block or the yellow "?" block for example)

it would be lots of programming if its possible with irrlicht, but i think its not. better use newton

You could cast a short ray straight up from your character, and use it to select the bounding box of a node (use a bitmask for bounding box selection).

This is assuming you're doing a 3d project. I don't know how to do it in 2d, although it may be something similar.

Check the collision tutorial on using a Ray, and then search the forums for ID Bitmasks.

That seems like it would work as well. Also, if world is 3d but gameplay 2d, then there wouldn't be a difference, but if you are using sprites, as in fully 2d, then collision detection suddenlky gets big changes...

good idea... i will try this

but i thought that irrlicht has a easier way to detect collided scenenode´s name, id, pointer or whatever...

and if i write my own code i will post it on Code snipets
