A simple change in Hello World project - crash the programm

[mcunha98]

Hi,

I try load a X file (replacing only the call to load MD2 file) in HelloWorld_vc8 project (vc++ .net)

Code: Select all

	//IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
	IAnimatedMeshX mesh = smgr->getMesh("d:/apl/blender/hp.x");
	//mesh.setCurrentAnimation (0);
	IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );

Its a basic change, but the compiler have same errors:

Try this:

Code: Select all

 //IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
   IAnimatedMeshX* mesh = smgr->getMesh("d:/apl/blender/hp.x");
   //mesh.setCurrentAnimation (0);
   IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh ); 

Remember, you create a pointer to the mesh.

I do, but receive a error:

Remove the X in the second line.

[kompromis]

you can't name both mesh

Hi,

try that one:

Code: Select all

//IAnimatedMesh* mesh = smgr->getMesh("../../media/sydney.md2");
   IAnimatedMesh* mesh = smgr->getMesh("d:/apl/blender/hp.x");
   //mesh.setCurrentAnimation (0);
   IAnimatedMeshSceneNode* node = smgr->addAnimatedMeshSceneNode( mesh );
