2D Parallax

前言

Parallax is an effect used to simulate depth by having textures move at different speeds relative to the camera. Godot provides the Parallax2D node to achieve this effect. It can still be easy to get tripped up though, so this page provides in-depth descriptions of some properties and how to fix some common mistakes.

备注

This page only covers how to use Parallax2D. This node is still experimental, so the implementation might change in future versions of Godot. However, it is still recommended to use over the ParallaxLayer and ParallaxBackground nodes.

Scroll scale

The backbone of the parallax effect is the scroll_scale property. It works as a scroll-speed multiplier, allowing layers to move at a different speed than the camera for each axis set. A value of 1 makes the parallax node scroll at the same speed as the camera. If you want your image to look further away when scrolling, use a value lower than 1, with 0 bringing it to a complete stop. If you want something to appear closer to the camera, use a value higher than 1, making it scroll faster.
