Camera2D (Mibo)

Camera2D Module

Namespace: Mibo.Elmish
Assembly: Mibo.Raylib.dll

Helper functions for 2D Cameras (Orthographic projection).

Use these for top-down, side-scrolling, or any 2D game rendering.

The raylib Camera2D is a native mutable struct. The read-only helpers (viewportBounds/screenToWorld/worldToScreen) take it by inref (no copy, use &camera at the call site), the movement helpers (smoothFollow/clampTarget) take it by byref and mutate it in place, and the config builders take it by value (the camera is stored in the config regardless).

Functions and values

Function or value	Description
`clampTarget camera minX minY maxX maxY` Full Usage: `clampTarget camera minX minY maxX maxY` Parameters: camera : `byref<Camera2D>` - Passed by reference (`&camera`) so mutations are visible to the caller. minX : `float32` minY : `float32` maxX : `float32` maxY : `float32` Modifiers: inline	Clamp the camera target to a world bounds rectangle. camera : `byref<Camera2D>` Passed by reference (`&camera`) so mutations are visible to the caller. minX : `float32` minY : `float32` maxX : `float32` maxY : `float32`
`create position zoom viewportSize` Full Usage: `create position zoom viewportSize` Parameters: position : `Vector2` zoom : `float32` viewportSize : `Vector2` Returns: `Camera2D` Modifiers: inline	Creates a raylib `Camera2D` centered on the given position. position : `Vector2` zoom : `float32` viewportSize : `Vector2` Returns: `Camera2D`
`render camera` Full Usage: `render camera` Parameters: camera : `Camera2D` Returns: `Camera2DConfig` Modifiers: inline	Create a rendering config from a 2D camera. Defaults: fullscreen, no clear. camera : `Camera2D` Returns: `Camera2DConfig`
`screenToWorld camera screenPos` Full Usage: `screenToWorld camera screenPos` Parameters: camera : `inref<Camera2D>` - Passed by read-only reference (`&camera`) to avoid copying the native struct. screenPos : `Vector2` Returns: `Vector2` Modifiers: inline	Converts a screen position (pixels) to world position. camera : `inref<Camera2D>` Passed by read-only reference (`&camera`) to avoid copying the native struct. screenPos : `Vector2` Returns: `Vector2`
`smoothFollow camera target speed` Full Usage: `smoothFollow camera target speed` Parameters: camera : `byref<Camera2D>` - Passed by reference (`&camera`) so mutations are visible to the caller. target : `Vector2` speed : `float32` Modifiers: inline	Smoothly interpolate the camera target toward a world position. camera : `byref<Camera2D>` Passed by reference (`&camera`) so mutations are visible to the caller. target : `Vector2` speed : `float32`
`splitScreenBottom camera clearColor` Full Usage: `splitScreenBottom camera clearColor` Parameters: camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig` Modifiers: inline	Split-screen bottom half. Clears with given color. camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig`
`splitScreenLeft camera clearColor` Full Usage: `splitScreenLeft camera clearColor` Parameters: camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig` Modifiers: inline	Split-screen left half. Clears with given color. camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig`
`splitScreenRight camera clearColor` Full Usage: `splitScreenRight camera clearColor` Parameters: camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig` Modifiers: inline	Split-screen right half. Clears with given color. camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig`
`splitScreenTop camera clearColor` Full Usage: `splitScreenTop camera clearColor` Parameters: camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig` Modifiers: inline	Split-screen top half. Clears with given color. camera : `Camera2D` clearColor : `Color` Returns: `Camera2DConfig`
`viewportBounds camera width height` Full Usage: `viewportBounds camera width height` Parameters: camera : `inref<Camera2D>` - Passed by read-only reference (`&camera`) to avoid copying the native struct. width : `float32` height : `float32` Returns: `Rectangle` Modifiers: inline	Calculates the visible world bounds for a raylib Camera2D. camera : `inref<Camera2D>` Passed by read-only reference (`&camera`) to avoid copying the native struct. width : `float32` height : `float32` Returns: `Rectangle`
`withClear color config` Full Usage: `withClear color config` Parameters: color : `Color` config : `Camera2DConfig` Returns: `Camera2DConfig` Modifiers: inline	Clear with this color before rendering. color : `Color` config : `Camera2DConfig` Returns: `Camera2DConfig`
`withViewport viewport config` Full Usage: `withViewport viewport config` Parameters: viewport : `Rectangle` config : `Camera2DConfig` Returns: `Camera2DConfig` Modifiers: inline	Set viewport in normalized screen coordinates (0-1). viewport : `Rectangle` config : `Camera2DConfig` Returns: `Camera2DConfig`
`worldToScreen camera worldPos` Full Usage: `worldToScreen camera worldPos` Parameters: camera : `inref<Camera2D>` - Passed by read-only reference (`&camera`) to avoid copying the native struct. worldPos : `Vector2` Returns: `Vector2` Modifiers: inline	Converts a world position to screen position (pixels). camera : `inref<Camera2D>` Passed by read-only reference (`&camera`) to avoid copying the native struct. worldPos : `Vector2` Returns: `Vector2`
