Hi
I have a network game that uses quakeworld style physics. Predict on clients and simulate on server, with server simulation able to correct past predictions on clients. I use CharacterControl. Ie, on clients the local player is a CharacterControl and enemies are just spatials. On server all players are CharacterControls that i just feed with client movement commands. They are created like this:
[java]
val tank = new Node(“Tank”)
tank.attachChild(tankGeo)
tank.setUserData(SceneGraphUserDataKeys.Player, ps)
val capsuleShape = tankCollisionShape
val capsuleShapeGhost = new CapsuleCollisionShape(0.4f, 0.4f, 1)
val playerControl = new CharacterControl(capsuleShape, 0.1f)
tank.addControl(playerControl)
getPhysicsSpace.add(playerControl)
playerControl.setUseViewDirection(false)
playerControl.setJumpSpeed(0);
playerControl.setFallSpeed(0.3f);
playerControl.setGravity(0.3f);
playerControl.setPhysicsLocation(new Vector3f(0, 2.5f, 0));
val ghost: GhostControl = new GhostControl(capsuleShapeGhost)
ghost.setCollisionGroup(PhysicsCollisionObject.COLLISION_GROUP_02)
ghost.setCollideWithGroups(PhysicsCollisionObject.COLLISION_GROUP_01) // Level
tank.addControl(ghost);
[/java]
Apart from that i have projectiles in collision group 3 (that collides with 1 and 2).
This all works swell! The last thing i need to fix is player-vs-player collision in the server simulation. I guess charactercontrol-vs-charactercontrol? Does someone have a good strategy for that? Right now player just walk through each other… so there is no collision handling going between them at all.
PS. Optional question: Also, if enemies on the client are just spatials. Can i take advantage of that and get some nice “for looks” spatial-vs-charactercontrol collision there? DS.
