Transform
| Available since LÖVE 11.0 |
| This type is not supported in earlier versions. |
Object containing a coordinate system transformation.
The love.graphics module has several functions and function variants which accept Transform objects.
Constructors
| love.math.newTransform | Creates a new Transform object. |  11.0 |
Functions
| Object:release | Immediately destroys the object's Lua reference. | 11.0 |
|
| Object:type | Gets the type of the object as a string. | ||
| Object:typeOf | Checks whether an object is of a certain type. | ||
| Transform:apply | Applies the given other Transform object to this one. | 11.0 |
|
| Transform:clone | Creates a new copy of this Transform. | 11.0 |
|
| Transform:getMatrix | Gets the internal transformation matrix stored by this Transform. | 11.0 |
|
| Transform:inverse | Creates a new Transform containing the inverse of this Transform. | 11.0 |
|
| Transform:inverseTransformPoint | Applies the reverse of the Transform object's transformation to the given 2D position. | 11.0 |
|
| Transform:isAffine2DTransform | Checks whether the Transform is an affine transformation. | 11.0 |
|
| Transform:reset | Resets the Transform to an identity state. | 11.0 |
|
| Transform:rotate | Applies a rotation to the Transform's coordinate system. | 11.0 |
|
| Transform:scale | Scales the Transform's coordinate system. | 11.0 |
|
| Transform:setMatrix | Directly sets the Transform's internal transformation matrix. | 11.0 |
|
| Transform:setTransformation | Resets the Transform to the specified transformation parameters. | 11.0 |
|
| Transform:shear | Applies a shear factor (skew) to the Transform's coordinate system. | 11.0 |
|
| Transform:transformPoint | Applies the Transform object's transformation to the given 2D position. | 11.0 |
|
| Transform:translate | Applies a translation to the Transform's coordinate system. | 11.0 |
Enums
| MatrixLayout | The layout of matrix elements (row-major or column-major). | 11.0 |
Supertypes
Notes
Transform objects have a custom * (multiplication) operator. result = tA * tB is equivalent to result = tA:clone():apply(tB). It maps to the matrix multiplication operation that Transform:apply performs.
The * operator creates a new Transform object, so it is not recommended to use it heavily in per-frame code.
