Conditionals

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

• Write readable conditional branches.
• Avoid unreachable choices and accidental infinite loops.
• Connect conditionals to variables and validation checks.

Core syntax

• if
• elif
• else
• while
• break
• continue

Runnable example

default money = 50

label shop:
    if money >= 100:
        e "你很有钱！"
    elif money >= 10:
        e "还过得去。"
    else:
        e "你身无分文。"

Study outline

• Start with the smallest example for conditionals.
• Test the key terms in a clean Ren'Py project: if, elif, else, while.
• 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/conditional.html

How this fits in GenPy

• Use Variables to document state names and Validation to catch branch mistakes before export.
• Use Story Graph when conditions reshape the route map.

Recommended GenPy docs:

• Variables
• Script Validation
• Story Graph
