General Local Avoidance

Hi,
I am testing the latest beta version 4.3.13 and demo Example11_RVO -> RVO does not work, I created a new project 2019.3.3f1 but it gives me 2 errors, I attach an image, the 2D demo RVOLightweight works and it is also superfast 100+ fps 30000 agents, I wanted to know if it doesn’t work just for me and how can i fix it.

#3

Or maybe it just wasn’t implemented yet, after all it’s a beta.

#4

Hi

Ah. Yeah it looks like I forgot to remove obstacles from that example scene in the beta. RVO obstacles are not implemented in the beta yet. You can remove the RVONavmesh component from that scene and I think it should work. However the agent may push each other off the navmesh sometimes.

#5

Hi,

now it works!
for the demo scene some small fixable error:
There are two Grounds, the second prevents you from seeing the agents, the “_TintColor” property is not present in the Particle / Unlit shader with “_Color” Cutout Overlay work.

Thanks for the support

#6

I’m trying the examples and reading the documentation to understand how to integrate A * Pathfinding into my project, I know it’s a beta, I send the errors that I find and I hope that a stable version will come out soon.

  • RecastExample: when I press “P” to throw obstacles it gives me errors:

Not allowed to access vertices on mesh ‘’ (isReadable is false; Read/Write must be enabled in import settings)
UnityEngine.Mesh:SetVertices(Vector3[], Int32, Int32)

Thanks for reporting that exception.
I made a similar fix for the 4.2 branch a few days ago but I didn’t think it was also a problem in the 4.3 branch. Turns out it was.
This exception is due to a recent change in how Unity handles mesh data uploads.

I have released beta version 4.3.14 now which fixes this issue: https://www.arongranberg.com/astar/download
