Problem with camera target

DeusXL · Post by **DeusXL** » Sat Mar 13, 2004 8:10 pm

I have create a camera scene node and when I want to do a rotation, the camera doesn't do anithing

I think it's because the target of the camera stay always the same and the rotation have no effect !

camera roation is just for the node - other nodes that are attached to the camera will rotate based on the cameras rotation.

Use setTarget() to change where the camera looks at

Ok but if I want a progressive rotation of the camera, must I set an Mesh invisible as target and put an animation on this mesh or there is another thing.
When I set a target it doesn't look pretty good

And when you setVisible(false) a Mesh, animation don't work but I find something who work ( well ? ) :

Code: Select all

cameratarget->setScale(vector3df(0.0f,0.0f,0.0f));

Please help me because I think there is another way

If you want progressive rotation then you'd need to keep an angle variable:

Code: Select all

int angle;

then keep updating the camera like so:

Code: Select all

angle ++;
float xTarget, yTarget;

xTarget = sin(PI*(angle/180)) * 10;
yTarget = cos(PI*(angle/180)) * 10;

core::vector3df campos = camera.getPosition();
core::vector3df newTarget = campos + vector3df(xTarget, campos.Y, yTarget);

camera.setTarget(newTarget);

That should make the cameras target rotate in a circle around the camera. Hope it helps
