- What do you want to achieve? Keep it simple and clear!
I want to set the ray cast position to behind the firepoint (an attachment in the viewmodel’s handle). So I can use the raycast to check if the player’s gun is close to a wall, and if it is move it back enough to where it is not gonna be clipping into the wall
- What is the issue? Include screenshots / videos if possible!
The math is incorrect, and I do not know the correct math, the calculation causes the positioning to be off from what I intend.
-
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I tried various different equations, and I am just stumped on how to do this, I thought
local positionBehind = cframe.Position - (forwardVector * length)
would be correct but I guess not
- there are no errors or warnings in output.
most of this code is not nessecary, but is here to give a bigger picture, look for the comment
