Diablo like game where i got to work with navmesh funneling import and stuff like that. Was fun but extremely frustating. Fix a small one case scenario bug and accidently create a thousand more bugs.
Navmesh
During this project i had the pleasure to develop a navmesh funneling system together with import from Unity and i thought this would just take a few weeks but i ended up managing the navmesh for the whole project time.
When i started out i started experimenting with a premade navmesh from a prior assigement to do my funneling on. A away from everything 2D space.
The green dots indicates the “right” corner, and the red smaller dots indicates the “left” corner. These are used to calculate the “cone“ that is mathematically used for the funneling algorithm.
When i finnaly got a semi working funneling i had to work with the import into our own game engine. But several problems was revealed. A: The mesh was far too small (simple fix, just multiply all the vertices with 100). And B: Unity created a unneccesary amounts of vertices that messed with my funneling.
Luckily we had Mathias Perez in our group, a programmer with knowledge on how to use Blender and removed several of the vertices for us
And eventually we had a really nice navmesh with the import working in 3D space. And another problem popped up. How do we handle elevation?
There was several techniques i could had used but i never got any of them to work so i made a quick fix. Raycast below the play and see if we intersect with the ground.
And in the end. Everything just kindea worked!
