collisions not working at angles

I am doing some testing with collisions. I have a large square thin object. I put a collision_start event on it and fire a gun at it. If I am straight on, the collisions get detected. If I am at an angle, but close, collisions get detected. If I am at an angle but a little bit away, the bullet passes visually through my object but no collision_start is getting called. If you stand behind the object, you actually see the bullets pass right through. If I walk closer or change my angle, the bullets hit my object (and stop as most bullets die on impact).

Ideas on this? I know the script is coded properly as it does detect the other collisions.

Is the object you're firing at phantom?

If you are firing bullets at something and the bullets aren't bouncing off, and instead are going straight through, then the physics engine isn't detecting the collision at all, so the script can't either. Is that what's happening?

Have you tried it in Havok 4?

The bullets do hit and collision is detected if firing from a different angle. It's not that the object isn't physical. I think it may have something to do with the bullet firing quickly and "jumping through" my solid object due to the speed of the projectile v.s. how often collisions are detected. The bullet isn't getting a collision either. But again, if shot straight on or at a different angle, the bullet and target both get valid collision detection events.

This is the same quirk that allows people to move through solid objects using high-speed physical movement (there are a number of products out there that boast this feature, like OmniPhase and TeleDash), and it still very much happens in Havok 4 (at least as of a couple weeks ago), though I'm not sure if the specifics, such as how fast and what kind of thicknesses will trick the engine, are the same. I don't know if that is still due to limitations in the physics engine, or if it was purposefully reintroduced as a design feature by LL, or what.

Take your projectile's speed and divide it by 45, that's how many meters it moves each tick. Objects collide if they would be intersecting on the next tick. A projectile 5.555 meters long can travel at 250 meters per second without going through anything.
