i was just adding water and i got theses errors...

We need code, but make sure node, mesh, and terrain are all valid variables.

so i fixed the first part and heres my code

i added this:

Code: Select all

scene::ISceneNode* node = 0;

	node = smgr->addAnimatedMeshSceneNode(mesh);
	node->setMaterialTexture(
   0, driver->getTexture("../../media/wall.jpg"));
	node->getMaterial(0).EmissiveColor.set(0,0,0,0);

into this and now im having trouble with mesh

Code: Select all

	mesh = smgr->addHillPlaneMesh("myHill",
		core::dimension2d<f32>(20,20),
		core::dimension2d<s32>(40,40), 0, 0,
		core::dimension2d<f32>(0,0),
		core::dimension2d<f32>(10,10));

	node = smgr->addWaterSurfaceSceneNode(mesh->getMesh(0), 3.0f, 300.0f, 30.0f);
	node->setPosition(core::vector3df(0,7,0));

	node->setMaterialTexture(0,	driver->getTexture("../../media/water.jpg"));

compile error:

and the first time mesh comes up in my whole code is here:

Code: Select all

node = smgr->addAnimatedMeshSceneNode(mesh);

the variable 'mesh' is not declared.

wtf i can't figure this out can someone please fix this for me
all i did was copy the code from the special effects tutorial

what did you do different im still getting the same errors

Code: Select all

.\main.cpp(46) : error C2065: 'mesh' : undeclared identifier
.\main.cpp(58) : error C2227: left of '->getMesh' must point to class/struct/union/generic type
        type is ''unknown-type''

bitplane · Post by **bitplane** » Sat Apr 01, 2006 5:32 am

i don't mean to be rude, but you really must know what an identifier (variable) is, and how to declare one before you can decipher the error message "\main.cpp(46) : error C2065: 'mesh' : undeclared identifier"

anyway, at risk of repeating myself-

www.cplusplus.com/doc/tutorial/variables.html

you really should read it

ya i know i gues im kinda getting on your nerves and im sorry but i've read that stuff before and i added int mesh; and this came up

Code: Select all

.\main.cpp(50) : error C2664: 'irr::scene::ISceneManager::addAnimatedMeshSceneNode' : cannot convert parameter 1 from 'int' to 'irr::scene::IAnimatedMesh *'
        Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
.\main.cpp(59) : error C2440: '=' : cannot convert from 'irr::scene::IAnimatedMesh *' to 'int'
        There is no context in which this conversion is possible
.\main.cpp(61) : error C2227: left of '->getMesh' must point to class/struct/union/generic type
        type is 'int'

That would be because the variable has to be declared as the correct type. addAnimatedMeshSceneNode returns an IAnimatedMesh, not an int. You'll need to declare the variable 'mesh' as an IAnimatedMesh, much like this:

IAnimatedMesh* mesh;

OK THX FOR ALL THE HELP!!!
i got it to work

i just had to add

Code: Select all

	scene::[b]IAnimatedMesh* mesh[/b] = smgr->getMesh(
		"../../media/room.3ds");

	smgr->getMeshManipulator()->makePlanarTextureMapping(
		mesh->getMesh(0), 0.004f);

and theres the IAnimatedMesh* right there in the code
