Efficiently create hundreds of meshes
[UnityScript] So in my project there is a need to create the map procedurally (in runtime). However simple it requires to make hundreds if not thousands of a single prefab then combining them into a couple meshes. This obviously gets pretty messy to code and is a hard hit to the CPU for a couple seconds. Is there any other way besides instantiating every single segment then combining them into a couple meshes because this seems like a crude way to do it. Or is there a way that makes it easier on the CPU, and quicker?
Rather than generating the pieces as objects that you then combine the meshes of, the alternative is to build the (combined) mesh directly. See the Mesh documentation for details.
I don't really see anything on the doc, can you point me at a function or instruction that can help?
That documentation shows how to build a $$anonymous$$esh from scratch. That's the way to get the performance you desire.
So I would take the vertices of every mesh I want to build in each segment then create a mesh of them all. Cool
Correct. You can look at the CombineChildren script for a big example. Indeed, you could make your script based on that, since it ultimately boils down to a list of meshes and positions, exactly as you have.
Better still, the $$anonymous$$eshCombineUtility script which is uses to do the actual combining looks exactly like what you want!
