Who can help me how to use Mouse in 3D Screen? like 3D RPG, RTS... games...

In Irrlicht you can use functions like

irr::scene::ISceneCollisionManager::getSceneNodeFromScreenCoordinatesBB

to check what scene node is under mouse cursor.
To check exactly point under mouse cursor use...

Code: Select all

core::line3d<f32> irr::scene::ISceneCollisionManager::getRayFromScreenCoordinates

...to get line from camera to mouse position in 3D world and then

Code: Select all

bool irr::scene::ISceneCollisionManager::getCollisionPoint

First, you'll get more responses if you post this in the Beginners Questions forum.

You'll have to give us more information.

Why can't you use the mouse?

What are you trying to do with it, what do you expect to happen, and what do you see happening instead?

Check the tutorials...

The GUI tutorial shows you how to use the mouse with the GUI and one of the tutorials using the Quake 3 map shows you how to to scenenode picking with the mouse which may be closer to what you're after.

Hi huydotnet!
I think you can search in the forum. And in the Tut7 use the mouse for FPS camera, if you want use your custom Camera (as RPG Camera) you must change some code. (getCursorControl(); getSceneCollisionManager(); getRayFromScreenCoordinates(); getSceneNodeFromRayBB())... hope this may help.

You guys are all here??

.\main.cpp(128) : error C2664: 'irr::scene::ISceneManager::createTriangleSelector' : cannot convert parameter 1 from 'irr::scene::IAnimatedMesh *' to 'irr::scene::IMesh *'

change the animatedMesh to animatedMesh->getMesh(0)
