Casts a ray against the shape. The Shape can be transformed to get it into the desired position.
Function
Synopsis
x, y, fraction = Shape:rayCast( x1, y1, x2, y2, maxFraction, tx, ty, tr, childIndex )
Arguments
number x1
- The x position of the ray starting point.
number y1
- The y position of the ray starting point.
number x2
- The x position of the ray end point.
number y1
- The y position of the ray end point.
number maxFraction
- The maximum distance the ray is going to travel as a number from 0 to 1.
number tx
- The translation of the shape on the x-axis.
number ty
- The translation of the shape on the y-axis.
number tr
- The shape rotation.
number childIndex (1)
- The index of the child the ray gets cast against.
Returns
