Clipping problem.

[egglord3344]

as you can see the gun seems to go right through the column when it's not suppose to, wonder if it's because it's the child of another scene node or i forgot to set a flag to enable clipping or what ever it's called? (Z enable?) anyways, hope you guy can help me, i've basically did everything my self programatically but have a long ways to go, just want to fix this clipping issue.[/img]

The z-buffer just tries to assure that objects are drawn over the ones behind them. It doesn't prevent objects from going through each other. To stop that you should take a look at collision detection.

Same problem here ...
I did slight modifications to the "Loading Scenes from .irr Files" example

First i iterate through all the nodes available in the scene, and for nodes of type ESNT_MESH (the gun is an IMesh), i do the following

Code: Select all

selector = smgr->createTriangleSelector(((scene::IMeshSceneNode*)node)->getMesh(), node);

Then the selector is added to meta selector

Code: Select all

meta->addTriangleSelector(selector);

Then I create an animator,

Code: Select all

	anim = smgr->createCollisionResponseAnimator(
		meta, gunnode, core::vector3df(200,200,200),
		core::vector3df(0,0,0));
	meta->drop(); // I'm done with the meta selector now
	gunnode->addAnimator(anim);
	anim->drop(); 

But when I execute the code, the camera collision works fine, but the gun clips through the scene contents!!!

i guess thats your weapon inside the wall. you can fix that by deactivating the ZBuffer for the gun.
only disable ZBuffer not zwrite!

Hi Sudi, Thanks for the reply.
I tried what you suggested, now it works with opengl, but when i use directx, the gun mesh goes behind everything in the scene. (as if it is in the bottom-most layer, and other objects in the scene are displayed over it!!!)

any suggestions?

i guess d3d handles the zbuffer flags different? dunno
do you need d3d? do you have to support both drivers?

[joshua1091]

No... not at all...
just coding for fun, thought it would be cool if both the drivers could be used!!!
anyway, thank you... will dig deeper and see if i could find any answer!!
do let me know in case you could think of some solution.

There are only a few little differences when rendering to RTTs. Otherwise, both drivers will behave the same.

are You working just with IMesh, not an IAnimatedMeshSceneNode?


Is drawn IMesh?
