FluidBackend

FluidBackend is an interface making it possible to bind Fluid to a library other than Raylib. Another built-in backend is fluid.simpledisplay.SimpledisplayBackend for arsd.simpledisplay.

The default unit in graphical space is a **pixel** (px), here defined as **1/96 of an inch**. This is unless stated otherwise, as in Texture.

Functions

area Rectangle area(Rectangle rect): Set area within the window items will be drawn to; any pixel drawn outside will be discarded.
area Rectangle area(): Undocumented in source.
deltaTime float deltaTime(): Get time elapsed since last frame in seconds.
dpi Vector2 dpi(): Get horizontal and vertical DPI of the window.
drawLine void drawLine(Vector2 start, Vector2 end, Color color): Draw a line.
drawRectangle void drawRectangle(Rectangle rectangle, Color color): Draw a rectangle.
drawTexture void drawTexture(Texture texture, Rectangle rectangle, Color tint, string altText): Draw a texture.
drawTextureAlign void drawTextureAlign(Texture texture, Rectangle rectangle, Color tint, string altText): Draw a texture, but ensure it aligns with pixel boundaries, recommended for text.
drawTriangle void drawTriangle(Vector2 a, Vector2 b, Vector2 c, Color color): Draw a triangle, consisting of 3 vertices with counter-clockwise winding.
hasJustResized bool hasJustResized(): True if the user has just resized the window.
hidpiScale Vector2 hidpiScale(): Get the DPI value for the window as a scale relative to 96 DPI.
inputCharacter dchar inputCharacter(): Get next queued character from user's input. The queue should be cleared every frame. Return null if no character was pressed.
isDown bool isDown(MouseButton ): Undocumented in source.
isDown bool isDown(KeyboardKey ): Undocumented in source.
isDown int isDown(GamepadButton button): Undocumented in source.
isPressed bool isPressed(MouseButton ): Check if the given mouse button has just been pressed/released or, if it's held down or not (up).
isPressed bool isPressed(KeyboardKey ): Check if the given keyboard key has just been pressed/released or, if it's held down or not (up).
isPressed int isPressed(GamepadButton button): Check if the given gamepad button has been pressed/released or, if it's held down or not (up) on any of the connected gamepads.
isReleased bool isReleased(MouseButton ): Undocumented in source.
isReleased bool isReleased(KeyboardKey ): Undocumented in source.
isReleased int isReleased(GamepadButton button): Undocumented in source.
isRepeated bool isRepeated(KeyboardKey ): If true, the given keyboard key has been virtually pressed again, through a long-press.
isRepeated int isRepeated(GamepadButton button): If true, the given gamepad button has been virtually pressed again, through a long-press.
isUp bool isUp(MouseButton ): Undocumented in source.
isUp bool isUp(KeyboardKey ): Undocumented in source.
isUp int isUp(GamepadButton button): Undocumented in source.
loadTexture Texture loadTexture(Image image): Load a texture from memory or file.
loadTexture Texture loadTexture(string filename): Undocumented in source.
mouseCursor FluidMouseCursor mouseCursor(FluidMouseCursor ): Get or set mouse cursor icon.
mouseCursor FluidMouseCursor mouseCursor(): Undocumented in source.
mousePosition Vector2 mousePosition(Vector2 ): Get/set mouse position
mousePosition Vector2 mousePosition(): Undocumented in source.
reaper TextureReaper* reaper(): Texture reaper used by this backend. May be null.
restoreArea void restoreArea(): Restore the capability to draw anywhere in the window.
scale float scale()
float scale(float ): Set scale to apply to whatever is drawn next.
scroll Vector2 scroll(): Get scroll value on both axes.
unloadTexture void unloadTexture(uint id)
void unloadTexture(Texture texture): Destroy a texture created by this backend. Always use texture.destroy() to ensure thread safety and invoking the correct backend.
windowSize Vector2 windowSize(Vector2 ): Get or set the size of the window.
windowSize Vector2 windowSize(): Undocumented in source.
