Components: The data attached to entities, like meshes, physics, or animations. Want collision? One Last Piece: The Collision System With almost every system in place, I’m now working on the Collision System—the last big piece of this rewrite. Want to add physics? setEntityKinetics(). setEntityCollision().

Most importantly, if the game crashes for any reason, the editor does not crash at the same time (which could cause data loss). GH-98163 ) CSGMesh3D now explicitly requires the mesh to be manifold. A manifold mesh must be closed, have each edge connected to only two faces, and have volume.

Even though we prepare these snapshots such that theyre suitable for general testing, backups and/or version control are recommended to prevent the loss of data.

Analysis The whole effect can be split into two parts, one for the simulation of the mesh and one for the rendering of the mesh. Combined with the knowledge of the rendering, the texture is actually very close to the rendering vertex data. Everything depends only on custom vertex data. Just pay attention to compatibility.

Godot 3.2 adds support for convex decomposition

Mircosoft Game Dev

APRIL 9, 2019

This makes the workflow for 3D games considerably easier, by allowing conversion of concave meshes of any form into a set of convex shapes. Triangle mesh shapes ( ConcavePolygonShape ) work very well as static colliders, but they are useless for rigid bodies or areas, as they have no internal volume. The convex problem.

Now the NavigationRegion can be added during gameplay, and it's possible to change its transform or even bake the navigation mesh data at runtime. The agent is also responsible for avoiding collisions. Collision avoidance dynamic map updates.
