I'm trying to make a prop_physics_override but restricting its rotations to yaw only. SOLID_BBOX/SOLID_OBB_YAW appear to be what I want but I haven't had any success in getting them to work. phys_keepupright seems to do what I want too but it seems like a stupid way of doing it.

edit: I would like to make it collide with playerclip brushes too!

Anyone have any ideas?

my relevant code:

new pp = CreateEntityByName( "prop_physics_override" );

	SetEntityModel( pp, "models/flag/briefcase.mdl" );
	SetEntityMoveType( pp, MOVETYPE_VPHYSICS );
	SetEntProp( pp, Prop_Send, "m_CollisionGroup", 1 );
	SetEntProp( pp, Prop_Send, "m_nSolidType", SOLID_OBB_YAW );

	DispatchSpawn( pp );

	decl String:name[ 32 ];
	Format( name, sizeof( name ), "FlagPhys%d", pp );

	DispatchKeyValue( pp, "targetname", name );
	DispatchKeyValue( pp, "disableshadows", "1" );
	AcceptEntityInput( pp, "DisableDamageForces" );
	//SetEntityRenderMode( pp, RENDER_ENVIRONMENTAL );

	TeleportEntity( flag, throwFrom, NULL_VECTOR, NULL_VECTOR );
	TeleportEntity( pp, throwFrom, NULL_VECTOR, throwVelocity );

	SetVariantString( name );
	AcceptEntityInput( flag, "SetParent" );

You could just use the override parameter, which is what that entity was designed for, and set the appropriate values. I think you are looking for damping or rotdamping, mabye inertia, i forget.

Then.. set the angle on TeleportEntity() once..

Setting inertiaScale didn't seem to work, and this also seems like a crappy way of doing it...

Override parameters https://developer.valvesoftware.com/...ysics_override

Override Parameters <string> A list of physics keyvalues that are usually embedded in the model. Format is key,value,key,value,...

And always, it depends what you are trying to accomplish.

Also does not work.

heres a snippet from my vehiclemod that i used to restrict vehicle rotation on certain axis, its based on the hl2 sdk code for the airboat antiflip

PHP Code:

// anti flip, not 100% effective.
    new PhysIndex = CreateEntityByName("phys_ragdollconstraint");
    
    if (PhysIndex == -1)
    {
        AcceptEntityInput(VehicleIndex, "Kill");
        
        PrintToServer("********** vehiclemod: could not create anti flip entity");
        return;
    }
    
    DispatchKeyValue(PhysIndex, "spawnflags", "2");
    DispatchKeyValue(PhysIndex, "ymin", "-50.0");
    DispatchKeyValue(PhysIndex, "ymax", "50.0");
    DispatchKeyValue(PhysIndex, "zmin", "-180.0");
    DispatchKeyValue(PhysIndex, "zmax", "180.0");
    DispatchKeyValue(PhysIndex, "xmin", "-50.0");
    DispatchKeyValue(PhysIndex, "xmax", "50.0");
    
    DispatchKeyValue(PhysIndex, "attach1", TargetName);
    
    DispatchSpawn(PhysIndex);
    ActivateEntity(PhysIndex);
    
    SetVariantString(TargetName);
    AcceptEntityInput(PhysIndex, "SetParent");
    
    TeleportEntity(PhysIndex, null, NULL_VECTOR, NULL_VECTOR); 


last time i checked SOLID_OBB_YAW wasn't implemented, also physics props will only work correctly with SOLID_VPHYSICS

Awesome, that works nicely.

Part 2: how can I make it bounce off playerclips?

tryL

SetEntProp( pp, Prop_Send, "m_CollisionGroup", 5 );

I have that already :p
