How to not draw objects?
I have a game with lots of objects, and I was wondering if I could reduce lag by not drawing/displaying them all at once. I know that you could do something like this:
if(!object.Renderer.isVisisble){ //if not seen
//do not display/draw function?
}
The problem is I don't a function that does not display it. In another program called Game Maker you can just use instance_deactivate_all() and then use instance_activate_region() and activate those you can see. If there something similar in Unity?
I think that Unity does frustum culling by default, that is determining which objects aren't in the camera's viewing frustum and not drawing them.
If you have Unity Pro, you can also play with occlusion culling, which is a feature that enables Unity to not draw objects that are completely hidden by other objects in front of them. http://docs.unity3d.com/Documentation/Manual/OcclusionCulling.html
If you only have Unity Free, you can make your own occlusion culling system if you need one.
I can't get it to work. I really need this for my voxel game. It is way too laggy.
