Clip this line to a rectangle.
If clipping was not successful, this object is undefined
rect | = Rectangle to clip to |
clipped | = On Return: true if the line could be clipped, false if line exists outside the rectangle |
|
inherited |
Return true if two line segments are collinear. (All points are on the same line.)
second | = The second line to check with |
|
inherited |
Return the intersection point of two lines.
second | = Second line. |
intersect | = On Return: The intercept. If the lines are parallel, this contains this line's first point |
|
inlineinherited |
Get the midpoint of this line.
|
inherited |
Return true if two line segments intersect.
second | = Second line. |
collinear_intersect | = true if a collision is reported when all points are on the same line. |
|
inherited |
Return the normal vector of the line from point A to point B.
When using CL_Vec2i, the vector is an 8 bit fraction (multiplied by 256)
