Question about camera trigger motion

[phamtuanchip]

Hi everyone,
I am new to Irrlicht Engine for my study, I try to build a Virtual Gallery with some camera observation and viewpoint
however I dont know how to trigger when my player go into the viewpoint
Is there anyone know how to code it?
Thank for sharing

Using ! setActiveCamera( ICameraSceneNode * camera ) in irr::scene::ISceneManager ! Hope this help !

For collision part you can check whether the AABB (axis-aligned bounding boxes) are intersecting each other. depending on which trigger's AABB is intersected, then you activate it.

Irrlicht has no event system, so the triggers have to be written by you. You can usee bounding-boxes like Virion proposed or any kind of invisible polygons to mark areas which collide. Then you have to check in code if your object is having a collisions with that area. If you want specific triggers for entering/leaving the area then you have to check constantly and create some trigger (event/message) when the collision state changes.

I'm not certain what exactly you are doing. But when I hear virtual gallery I wonder if maybe CobberCube might be something which would be easier to use for you. It's from the same author who wrote Irrlicht originally, but is a 3d engine that runs in browsers. And it has already an event system (called actions/events there) for triggers like proximity and clicking objects. Also your gallery would then even run online.
