ViewportTransform class



ViewportTransform(Vector2 e, Vector2 c, double scale)


center Vector2
center of the viewport.
read / write
extents Vector2
This is the half-width and half-height. This should be the actual half-width and half-height, not anything transformed or scaled.
read / write
hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
scale double
Returns the scaling factor used in converting from world sizes to rendering sizes.
read / write
translation Vector2
The current translation is the difference in canvas units between the actual center of the canvas and the currently specified center. For example, if the actual canvas center is (5, 5) but the current center is (6, 6), the translation is (1, 1).
read / write
yFlip bool
if we flip the y axis when transforming.
read / write


getScreenToWorld(Vector2 argScreen) Vector2
Takes the screen coordinates and return the corresponding world coordinates
getWorldToScreen(Vector2 argWorld) Vector2
Takes the world coordinates and return the corresponding screen coordinates
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
setCamera(double x, double y, double s) → void
Sets the transform's center to the given x and y coordinates, and using the given scale.
toString() String
A string representation of this object. [...]


operator ==(Object other) bool
The equality operator. [...]
