Can someone create for me a sample source for player movement(camera follow player) my englisch ist no good and i cant understand tutorial in this site :/ HELP

The camera doesnt 'follow' the player.

Code: Select all

scenemgr->addCameraSceneNodeFPS();

should be enough. this is assuming your scenemanager goes by the name scenemgr.

that creates a first person camera. did you mean you wanted that or a third person camera, like WoW?

of course i want create third person like WoW camera

I suppose you could create a regular ICameraSceneNode, and then setting its target to the player. Camera movement could then be employed with the event receiver (getting mouse movement). This is tricky math though.

i think

Code: Select all

 scenemgr->addCameraSceneNodeMaya()

might be able todo something like that, but ive never used it before.

No liger13 this will not help. Maya camera is just first person with click and drag. I think this here will help you http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=18074

@up
thanks man but i cant compile WoW movements :/ i have error
@topic
where i can put this code :

Code: Select all

thats part of an eventReciever class i think. just add it to the device with

Code: Select all

device->setEventReceiver();
