May be i’m off on a tangent, but my game has no ‘terrain’ or anything of the sorts. I place enemies, obstacles and goals in the scene, and want to have the enemies move towards the goal, avoiding the obstacles. I’m beginning with simple steering mechanism (seek, avoid etc. from tuts+), but at some point it would be nice to be able to do Theta* or A* for their pathfinding. Without any terrain to use as base for navmesh - where do I start? Do I use a ‘blank’ terrain and go from there, or is there any way to do this starting from a blank navmesh…
My game is only 2d (top-down).
The idea would be to subtract the obstacles from the navmesh ‘walkable’ area every time obstacles are placed. Does that make sense?
Looking for any help or directions to sources that deal with ‘not having any terrain to base it off’
