Projectiles not colliding with StaticShapes

#1 Are you using a project with PhysX enabled?
StaticShape objects will not be added to the list of collectible objects if so.

#2 Gibby,

I am not seeing anything wrong with the scripts. Are you certain there is a proper collision mesh associated with the model? Try selecting 'visible mesh' as the collision type and see if that works. If it does, then I am betting there is a problem with the collision mesh or the detail stack in the model.

#3 @AF:

Nope, no physX

@Ron:

I'm certain the collision is correct. I can't walk through the model with a player but bullets go straight through. As a control experiment, I imported it into TGE and it works fine, projectiles collide with it. I found this same issue with stock 1.2 as well as 3.5 MIT...


FWIW they were rigged with DoIT!, and have correct Torque Bounds/collision... collision works on the TSStatic just fine, whether in collision mesh or visible mesh. I wasn't aware you could have the collision/visible option on a StaticShape. What mystifies me is that they work fine as TSStatics but not StaticShape.

#4 In one of the projectile source files there is a list of what they can collide with. I don't think I saw staticshapes on that list, so you may have to add them in.

#5 @alphaslime: That's what I looked into as well, but in projectile.cpp

IMPLEMENT_CALLBACK( ProjectileData, onCollision, void, ( Projectile* proj, SceneObject* col, F32 fade, Point3F pos, Point3F normal ),
                   ( proj, col, fade, pos, normal ),
				   "@brief Called when a projectile collides with another object.\n\n"
                   "This function is only called on server objects."
				   "@param proj The projectile colliding with SceneObject col.\n"
				   "@param col The SceneObject hit by the projectile.\n"
				   "@param fade The current fadeValue of the projectile, affects its visibility.\n"
				   "@param pos The position of the collision.\n"
                   "@param normal The normal of the collision.\n"
				   "@see Projectile\n"
				  );

const U32 Projectile::csmStaticCollisionMask =  TerrainObjectType | StaticShapeObjectType;

const U32 Projectile::csmDynamicCollisionMask = PlayerObjectType | VehicleObjectType;

const U32 Projectile::csmDamageableMask = Projectile::csmDynamicCollisionMask;

U32 Projectile::smProjectileWarpTicks = 5;

then in projectile.h

protected:

   static const U32 csmStaticCollisionMask;
   static const U32 csmDynamicCollisionMask;
   static const U32 csmDamageableMask;   
   static U32 smProjectileWarpTicks;

..so it seems it should collide with a StaticShape.

#6 After further research, I found that if I open the shape in the shape editor, strip off the collision mesh and generate a new one in the TSShapeConstructor, bullets collide with it. Problem is the shape editor will only allow me to implement a big square box for a collision shape, which looks incredibly stupid when a decal sticks to it. I still don't understand why the models' inherent collision can work for everything else but projectiles...

#7 I have the same situation as Gobby has described in previos post.

#8 Sergii:

Your MAX setup looks correct. Unfortunately I still haven't found a cure for this issue...
