Transitions

This page is part of the GenPy Ren'Py learning path. It focuses on practical Ren'Py 8.x production and links each concept back to the GenPy workflow.

Learning goals

• Choose transitions for story pacing, not just visual novelty.
• Use built-in transitions first.
• Understand where transitions attach to scene/show/hide changes.

Core syntax

• with
• dissolve
• fade
• move
• transition

Runnable example

define slow_dissolve = Dissolve(2.0)            # 2 秒溶解
define long_fade = Fade(0.5, 0.0, 0.5)          # 出/停/入
define pix = Pixellate(1.0, 5)

label start:
    scene bg room
    with slow_dissolve

Study outline

• Start with the smallest example for transitions.
• Test the key terms in a clean Ren'Py project: with, dissolve, fade, move.
• Move the pattern back into your real project only after the example runs.
• Use GenPy docs and validation to keep the feature connected to story, assets, and export readiness.

Common pitfalls

• Test the smallest working script before layering on visual or UI complexity.
• Run Ren'Py Lint before release builds, even when the script appears to run locally.
• Keep examples in standard .rpy files so they remain editable outside GenPy.

Official references

• Ren'Py official reference: https://www.renpy.org/doc/html/transitions.html

How this fits in GenPy

• Use Performance Editor to preview scene rhythm and keep transition choices consistent.
• Export and test in Ren'Py when timing matters.
