Camera2D (Mibo)

Camera2D Module

Namespace: Mibo.Elmish
Assembly: Mibo.MonoGame.dll

Helper functions for 2D Cameras (Orthographic projection).

Use these for top-down, side-scrolling, or any 2D game rendering. The camera struct's fields are immutable, so the movement helpers (smoothFollow / clampTarget) return a new camera rather than mutating in place.

Functions and values

Function or value	Description
`clampTarget camera minX minY maxX maxY` Full Usage: `clampTarget camera minX minY maxX maxY` Parameters: camera : `Camera2D` minX : `float32` minY : `float32` maxX : `float32` maxY : `float32` Returns: `Camera2D` Modifiers: inline	Clamp the camera position to a world bounds rectangle, returning a new camera. camera : `Camera2D` minX : `float32` minY : `float32` maxX : `float32` maxY : `float32` Returns: `Camera2D`
`create position zoom viewportSize` Full Usage: `create position zoom viewportSize` Parameters: position : `Vector2` - World position the camera follows. zoom : `float32` - Zoom factor (1.0 = default). viewportSize : `Vector2` - Size of the viewport in pixels (used to compute origin). Returns: `Camera2D` Modifiers: inline	Creates a Camera2D centered on the given position. position : `Vector2` World position the camera follows. zoom : `float32` Zoom factor (1.0 = default). viewportSize : `Vector2` Size of the viewport in pixels (used to compute origin). 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 : `Camera2D` screenPos : `Vector2` Returns: `Vector2` Modifiers: inline	Converts a screen position (pixels) to world position. camera : `Camera2D` screenPos : `Vector2` Returns: `Vector2`
`smoothFollow camera target speed` Full Usage: `smoothFollow camera target speed` Parameters: camera : `Camera2D` target : `Vector2` speed : `float32` Returns: `Camera2D` Modifiers: inline	Smoothly interpolate the camera position toward a world position, returning a new camera. camera : `Camera2D` target : `Vector2` speed : `float32` Returns: `Camera2D`
`splitScreenBottom camera clearColor bounds` Full Usage: `splitScreenBottom camera clearColor bounds` Parameters: camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` - Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig` Modifiers: inline	Split-screen bottom half. Clears with given color. camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig`
`splitScreenLeft camera clearColor bounds` Full Usage: `splitScreenLeft camera clearColor bounds` Parameters: camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` - Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig` Modifiers: inline	Split-screen left half. Clears with given color. camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig`
`splitScreenRight camera clearColor bounds` Full Usage: `splitScreenRight camera clearColor bounds` Parameters: camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` - Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig` Modifiers: inline	Split-screen right half. Clears with given color. camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig`
`splitScreenTop camera clearColor bounds` Full Usage: `splitScreenTop camera clearColor bounds` Parameters: camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` - Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig` Modifiers: inline	Split-screen top half. Clears with given color. camera : `Camera2D` clearColor : `Color` bounds : `Rectangle` Parent viewport bounds in pixels (typically the window size). Returns: `Camera2DConfig`
`toMatrix c` Full Usage: `toMatrix c` Parameters: c : `Camera2D` Returns: `Matrix` Modifiers: inline	Computes the `SpriteBatch` transform matrix for this camera. The matrix applies: translate by -position, rotate, scale by zoom, then translate by origin. Pass this to `SpriteBatch.Begin(transformMatrix=...)`. c : `Camera2D` Returns: `Matrix`
`viewportBounds camera width height` Full Usage: `viewportBounds camera width height` Parameters: camera : `Camera2D` width : `float32` height : `float32` Returns: `Rectangle` Modifiers: inline	Calculates the visible world bounds for a MonoGame Camera2D. The result is a pixel `Rectangle` (MonoGame's `Rectangle` is int-based). camera : `Camera2D` 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 pixel coordinates. viewport : `Rectangle` config : `Camera2DConfig` Returns: `Camera2DConfig`
`worldToScreen camera worldPos` Full Usage: `worldToScreen camera worldPos` Parameters: camera : `Camera2D` worldPos : `Vector2` Returns: `Vector2` Modifiers: inline	Converts a world position to screen position (pixels). camera : `Camera2D` worldPos : `Vector2` Returns: `Vector2`
