Alright,
I need help for a shooting game I'm working on.
I current have a box that is 3d ( x, y, z)
I'm trying to perform a check to see if my cursor is inside this 3D box.
I understand how to make it 2d by using the max and min values but that creates a 2D box which will say I'm inside the box when in reality I'm not.
Hope someone understand this.
Maybe ill draw a pic and post it.
Its the same as checking for a point in a 2D rectangle. But depending on the view of the person, you need to determine which face of the cube to check on.
I need to check if mouse is inside the box but not in the red area
- Rotate the world axis such that the cube has no rotation( i.e 'unrotate' the cube relative to the world axis)
- transform the point to be relative to the cube's position
- check if the relative point is in the un-rotated cube by doing simple bounding min-max check
Do you have any examples for this?
