Camera2D

2D camera for scrolling games.

API

class simvx.core.nodes_2d.camera.Camera2D(**kwargs)

Bases: simvx.core.nodes_2d.node2d.Node2D

2D camera for scrolling games.

Provides target following with smoothing, zoom, viewport bounds/limits, and screen shake effects. The active Camera2D’s offset is applied by the renderer to all 2D draw calls.
