| ime::Transform::Transform | ( | ) |
Default constructor.
| Vector2f ime::Transform::getOrigin | ( | ) | const |
Get the local origin of the object.
| Vector2f ime::Transform::getPosition | ( | ) | const |
Get the position of the object.
| float ime::Transform::getRotation | ( | ) | const |
Get the orientation of the object.
The rotation is always in the range [0, 360]
| Vector2f ime::Transform::getScale | ( | ) | const |
Get the current scale of the object.
| void ime::Transform::move | ( | float | offsetX, |
| float | offsetY | ||
| ) |
Move the object by a given offset.
| offsetX | Horizontal offset |
| offsetY | Vertical offset |
This function adds to the current position of the object, unlike setPosition which overwrites it
| void ime::Transform::move | ( | Vector2f | offset | ) |
Move the object by a given offset.
| offset | Offset to apply |
This function adds to the current position of the object, unlike setPosition which overwrites it
Add an event listener to a property change event.
| callback | The function to be executed when a property changes |
Note that only one callback may be registered at a time. The new callback overwrites the previous one. The callback is passed the property that changed on invocation. Pass nullptr to cancel the callback.
| void ime::Transform::rotate | ( | float | angle | ) |
Rotate the object.
| angle | Angle of rotation, in degrees |
This function adds to the current rotation of the object, unlike setRotation which overwrites it
| void ime::Transform::scale | ( | float | factorX, |
| float | factorY | ||
| ) |
Scale the object by an offset.
| factorX | Horizontal scale factor |
| factorY | Vertical scale factor |
This function multiplies the current scale of the object, unlike setScale which overwrites it
| void ime::Transform::scale | ( | Vector2f | offset | ) |
Scale the object by an offset.
| offset | Offset to apply |
This function multiplies the current scale of the object, unlike setScale which overwrites it
| void ime::Transform::setOrigin | ( | float | x, |
| float | y | ||
| ) |
Set the local origin of the object.
| x | X coordinate of the new origin |
| y | Y coordinate of the new origin |
The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation).
The default origin of a transformable object is (0, 0)
| void ime::Transform::setOrigin | ( | Vector2f | origin | ) |
Set the local origin of the object.
| origin | New origin |
The origin of an object defines the center point for all transformations (position, scale, rotation). The coordinates of this point must be relative to the top-left corner of the object, and ignore all transformations (position, scale, rotation). The default origin of a transformable object is (0, 0)
| void ime::Transform::setPosition | ( | float | x, |
| float | y | ||
| ) |
Set the position of the object.
| x | X coordinate of the new position |
| y | Y coordinate of the new position |
This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).
| void ime::Transform::setPosition | ( | Vector2f | position | ) |
Set the position of the object.
| position | New position |
This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable object is (0, 0).
| void ime::Transform::setRotation | ( | float | angle | ) |
Set the orientation of the object.
| angle | New rotation, in degrees |
This function completely overwrites the previous rotation. See the rotate function to add an angle based on the previous rotation instead. The default rotation of a transformable object is 0
| void ime::Transform::setScale | ( | float | factorX, |
| float | factorY | ||
| ) |
Set the scale factors of the object.
| factorX | New horizontal scale factor |
| factorY | New vertical scale factor |
This function completely overwrites the previous scale
| void ime::Transform::setScale | ( | Vector2f | scale | ) |
Set the scale factor of the object.
| scale | New scale |
This function completely overwrites the previous scale
