Is it possible that my meshs, which don't check against each other because they aren't dynamic, would begin checking against each other when added to a group? It's possible. Kinematic entities belong to the CollisionRules.DefaultKinematicCollisionGroup by default which has a rule of NoBroadPhase wi...

Is it possible that my meshs, which don't check against each other because they aren't dynamic, would begin checking against each other when added to a group? Also, is symmetric? Like esxolusProjectileGroup = new CollisionGroup(); CollisionGroupPair pairEP = new CollisionGroupPair(esxolusProjectileG...

Nope, no specific or personal rules, I'm only using the groups. But the groups seem to be creating tremendous amounts of lag instead of being helpful. All the groups I use, I have them ignore BroadPhase, so I figured this should make them faster. It's laggier than without the groups. I'm using them ...

Hi, I'm trying to use the collision groups to get my lasers to just ignore each other, but it seems they aren't working like how I expect them to. if (!collisionSet) { projectileGroup = new CollisionGroup(); CollisionGroupPair pair = new CollisionGroupPair(projectileGroup, projectileGroup); Collisio...

I'm only using the Sphere, Box (well, not actually using it, but I do have it in the engine), and MobileMesh and they don't seem to have a CollisionRules.AddRule. I can find a ((Sphere)detectionSphere.getPhysicsCollider()).CollisionInformation.CollisionRules.Specific.Add() but it doesn't seem to tak...

Hello, I know there's a bit of a guide on how to use the collision rules to avoid checking some collisions, but I guess I'm still rather confused on how to use it. Specifically I want to create turrets and place them on our ship. The ship has a collision mesh and the turrets will have spheres. I wan...

An Entity only has a rigid transform (Position and Orientation). The entity's Position and Orientation bring the MobileMeshShape from its shape local space into world space. ("Shape local space" includes the affine transform applied to the mesh vertex data, and the recentering translation...

Do you know what I might be doing wrong? Setting the Position causes it to not work; the WorldMatrix also doesn't work either. The initial AffineTransform is just applied to the vertex data when building the shape. Recentering will occur on the post-transformed vertices to bring everything into loc...

Hey, actually I just had two more questions. Turns out the new AffineTransform(_rotation, _position) works perfectly fine, and I don't need to do anything with local space. It's centered and everything already. The problem seems to stem from trying to move it. It'd be great if I could just give it a...

Is this correct? The graphic would align, but then the center of mass will not be physical. It will rotate around the model's origin instead. That's fine, I'd rather it rotated around its Maya center. Also, thanks for the demo. Hopefully I can get it working so I can see if everything's correct. Th...

The fact that the StaticMesh is not an entity may not fit well into your existing classes. The StaticMesh is not an Entity, and so is incapable of motion. If you want to keep a unified architecture with the expectation that there will be mobile meshes, then going with the MobileMesh would be okay, ...

Ah, thank you! A MobileMeshShape is an actual mesh, composed of triangles. Note that it's generally good idea to use an approximation instead of a mobile mesh; approximations are generally quite a bit faster. Also, if the mesh never moves, use StaticMesh instead. I tried that and I want to use the S...

Also, is there a way to draw the ConvexHull?

And what's the difference between the ConvexHull and MobileMeshShape?

Hello, I'm trying to just make use of the mesh collision features of the engine, but I seem to be having problems getting the collider to match up with the model. I'm making a space game and I just need meshes for the giant, static ships. private ConvexHull meshCollider; public CollisionMesh(Model _...
