Wall crash system help

[Alvise1309 (AnubisMan)]

I need help with this system I’m trying to achieve.

I need the wall break effect to be always facing and stick to the same face the dummy hits without using Raycasting if possible.

I’ve tried:

- CFrame:Lerp()
- CFrame.Angles()
- CFrame.fromOrientation()

pretty sure that whenevery you raycast towards a something, you get the normal value. you might wanna look at those gun tutorials that leave bulletholes

I’m not raycasting, I’m applying a force to the dummy and check with a hitbox if it hits the wall, and then I need to place the effect

[smellfish_360]

if the dummy goes too fast against a thin wall it is likely to go straight through without detecting a collision. for projectile collision detection, using raycasting is always reccomended.
what you can do for instance, is to define a nextpos, raycast between the currentpos and the nextpos, and if there’s nothing in between, you could put it there.

Could work, but I’m using a RotatedRegion3 (https://devforum.roblox.com/t/rotated-region-3-module/334068) to detect if it hits the waall, so I just need to know how to face the effect

Surface normal help

The third value that FindPartOnRay() returns, is the surface normal of the area that was hit. You can use this to orientate your spray paint part’s orientation to match the orientation of the hit surface. Some example code: local hit, pos, normal = game.Workspace:FindPartOnRay(ray) --normal is a vector that points in a certain direction local SprayPaintPart = game.ServerStorage.SprayPaintPart:Clone() SprayPaintPart.Parent = workspace SprayPaintPart.CFrame = CFrame.new(pos, pos + normal) …

Looks like there’s a raycast method for that. If you’re still not considering raycast, your option is limited to the so-called cross product to get the normal.

I’ve tried that solution and it works so good, thanks so much!
