Question Regarding actors and physics

[alvarofer0021]

So Hello! ... As the tread title says im wondering if i can make my actors have Physics aka they collide with everything and react to every impulse or hit

I was thinking about moving everything into skeletal meshes and then just create a Physic Asset and well Spawn my actors and turn it on but im not sure about how much network impact or perfomance impact this can have Since the items are only "Pickupeable Actors" So if anyone has some experience on this feel free to point me in the right direction

sorry about the double tread i had some issues and it duplicated

KActors could also work for you. Although there's no real difference if your SkeletalMeshes are "static" anyways and only have a single body in the Physics Asset.

I made a test map for UT3 with around 500 of those and it was lagging pretty bad in a local game. But my machine was pretty bad as well. Just barely able to run the game/editor. Probably the same with networking. Loads of additional stuff to send compared to a static never-changing mesh.

Look into the PHAT editor for a physics asset.

So basicly i can just use KActors set the phys mode to Rigid Body and thats it?

[UnrealEverything]

Pretty much, except I missunderstood what you are trying to do.
You might have to set bWakeOnLevelStart, or call WakeRigidBody(). Something like that, just check those classes.

There is also a setting which allows pawns to push them...

Ok well what i was triying to do is make my Pickupeable items have physics and react with the world instead of being completly static and not reacting at all Thats pretty much it

[alvarofer0021]

Sorry for the Problems!! i have one last Deal I cant get it to react with Physics i Tried using Both bWakeOnLevelStart ,WakeRigidBody() and neither of those make my object not static

i also tried using the diferent physics states Rigid Body,Soft Body etc and it had no effect at all

Anyway here is my code if that helps

class Wood extends KActorSpawnable placeable;

var() editconst const CylinderComponent	CylinderComponent;






defaultproperties
{
  

    Begin Object class=SkeletalMeshComponent Name=BaseMesh
        SkeletalMesh=SkeletalMesh'CTF_Flag_IronGuard.Mesh.S_CTF_Flag_IronGuard'
        Scale = 1.5
        LightEnvironment=MyLightEnvironment
    End Object
    Components.Add(BaseMesh)
    bCanBeDamaged = true
    Begin Object Class=CylinderComponent NAME=CollisionCylinder
	
		CollisionRadius=+0040.000000
		CollisionHeight=+0040.000000
		bAlwaysRenderIfSelected=true
			BlockNonZeroExtent=true
		BlockZeroExtent=true
		BlockActors=true
		CollideActors=true
	End Object
	CollisionComponent=CollisionCylinder
	CylinderComponent=CollisionCylinder
	Components.Add(CollisionCylinder)
bBlockActors=true
bCanBeDamaged = false



        bCollideWorld=true
	bHidden=false
	bCollideActors=true
	bStatic=false
	bWakeOnLevelStart = true
	bWake
	bDamageAppliesImpulse = true

}

class Wood extends KActorSpawnable placeable;

defaultproperties
{
    Begin Object Name=StaticMeshComponent0
        StaticMesh=StaticMesh'phystest_resources.RemadePhysBarrel'
        Scale=1.5f
    End Object

    bCanBeDamaged = true
    bBlockActors=true
    bCollideWorld=true
    bHidden=false
    bCollideActors=true
    bStatic=false
    bWakeOnLevelStart=true
    bDamageAppliesImpulse=true
}

The problem was that you were creating a skeletal mesh component and cylinder collision component. Unreal can't simulate cylinder collision components as rigid bodies.
