IrrNewt 0.4, slow problem?

[beshrkayali]

hey all,
I'm working on project that has 8 nodes, and a level node
I want all of the 8 nodes to be added to IrrNewt Physics World, but i'm having a problem.
I tried to do it with only one node, it worked fine.
but with 8 nodes, it became soooo slow.

how can i solve this problem?

here i my physics code, i donnu, maybe there is something wrong with it:

Code: Select all

any one wanna answer me over here????
if there is something wrong with my question, tell me, so i can make it right? it's really really important

you should implement graphics debug information (p_world->drawAllDebugInfos() after smgr->drawAll() ) to check that all is ok. Also post the FPS with 1 box and the tree collision body and the FPS with 8 boxes and the tree

are you sure it is the physics have you tried comparing results with/without physics? Alot of the time it is graphics issues...

[beshrkayali]

well, i tried all of these thing.
i turns out that my mesh is really big, or not big, it has a lot of polygons.
i tried another object and it worked fine.
sorry, physics is just Great.
i think that i couldn't do it without IrrNewt.

I think that irrlicht should always come with IrrNewt integrated with it, becasue no one will make a game without physics.

You don't need physics for an FPS... or a sidescroller... or a space shooter... or tetris... or many other things.

i'm not doing an fps game, check this out:
