Locking a camera's movement on one axis

[pepeshka]

Hi all,

I'm working on a project where I want to lock an FPScamera on a single axis (I want no vertical movement). Turning off the vert movement bool in the constructor works to a point, but I've found that the camera can still move vertically via the collision system (for example, walking up a ramp). Is there any way to absolutely lock the camera in the engine so that it will never move along a defined axis?

just add something like

Code: Select all

vector3df target = camera->getPosition();
target.Y = 0;
camera->setPosition(target);

to your while (device->run()) loop

I don't think that would work well though, because OnAnimate is called right before rendering.

Well that's what I'm trying now, but the camera ends up getting stuck in the geometry. I think what happens is the camera moves a bit in the Y direction (just one "step" up a ramp, for example), then gets set back down to Y=0, which is inside the geometry.

ok, sorry but in this case you could take a look at the irrlicht source, on how it works inside...

Im sorry i dont have the time.
