This is particularly useful for mouse interaction with the shapes. By looping through all shapes and testing the mouse position with this function, we can find which shapes the mouse touches.
|
There's a bug in 0.8.0 preventing this function from working. |
Contents
Function
| Available since LÖVE 0.8.0 |
| This variant is not supported in earlier versions. |
Synopsis
hit = Shape:testPoint( tx, ty, tr, x, y )
Arguments
number tx- Translates the shape along the x-axis.
number ty- Translates the shape along the y-axis.
number tr- Rotates the shape.
number x- The x-component of the point.
number y- The y-component of the point.
Returns
boolean hit- True if inside, false if outside
Function
| Removed in LÖVE 0.8.0 |
| This variant is not supported in that and later versions. |
