| Modifier and Type | Method and Description |
|---|---|
Vec2 |
getCenter()
center of the viewport.
|
Vec2 |
getExtents()
This is the half-width and half-height.
|
void |
getScreenToWorld(Vec2 argScreen,
Vec2 argWorld)
takes the screen coordinates (argScreen) and puts the
corresponding world coordinates in argWorld.
|
void |
getScreenVectorToWorld(Vec2 argScreen,
Vec2 argWorld)
Transforms the given directional screen vector back to
the world direction.
|
void |
getWorldToScreen(Vec2 argWorld,
Vec2 argScreen)
takes the world coordinate (argWorld) puts the corresponding
screen coordinate in argScreen.
|
void |
getWorldVectorToScreen(Vec2 argWorld,
Vec2 argScreen)
Transforms the given directional vector by the
viewport transform (not positional)
|
boolean |
isYFlip() |
void |
setCamera(float x,
float y,
float scale)
Sets the transform's center to the given x and y coordinates,
and using the given scale.
|
void |
setCenter(float x,
float y)
sets the center of the viewport.
|
void |
setCenter(Vec2 argPos)
sets the center of the viewport.
|
void |
setExtents(float argHalfWidth,
float argHalfHeight)
This sets the half-width and half-height of the
viewport.
|
void |
setExtents(Vec2 argExtents)
This sets the half-width and half-height.
|
void |
setYFlip(boolean yFlip) |
boolean isYFlip()
void setYFlip(boolean yFlip)
yFlip - if we flip the y axis when transformingVec2 getExtents()
void setExtents(Vec2 argExtents)
argExtents - void setExtents(float argHalfWidth,
float argHalfHeight)
argHalfWidth - argHalfHeight - Vec2 getCenter()
void setCenter(Vec2 argPos)
argPos - void setCenter(float x,
float y)
x - y - void setCamera(float x,
float y,
float scale)
x - y - scale - void getWorldVectorToScreen(Vec2 argWorld, Vec2 argScreen)
