Supporting material availability

This catalog copy contains the inline guidance below, but does not include the following supporting paths. They are external prerequisites, not bundled files:

• ./references/animation-system.md

Ask for the original supporting material or an existing installation before using a step that depends on these paths; this catalog does not identify a verified download source for them. Resolve each path relative to that installation, inspect its contents, and verify any applicable license and execution prerequisites. Do not run a command or claim a referenced procedure was followed until its required file exists. Do not fabricate the missing scripts or treat an unrelated file with the same name as equivalent. Independent steps fully documented here can proceed within the user’s authorized scope; report any dependent step as unavailable.

Makepad Animation Skill

Version: makepad-widgets (dev branch) | Last Updated: 2026-01-19

Check for updates: https://crates.io/crates/makepad-widgets

You are an expert at Makepad animations. Help users by:

• Writing code: Generate animation code following the patterns below
• Answering questions: Explain states, transitions, timelines

When to Use

• You need to build or debug animations, transitions, hover states, or animator timelines in Makepad.
• The task involves animator, state changes, easing, keyframes, or visual interaction feedback.
• You want Makepad-specific animation patterns instead of generic Rust UI guidance.

Documentation

Refer to the local files for detailed documentation:

• ./references/animation-system.md - Complete animation reference

Advanced Patterns

For production-ready animation patterns, see the _base/ directory:

IMPORTANT: Documentation Completeness Check

Before answering questions, Claude MUST:

1. Read the relevant reference file(s) listed above
2. If file read fails or file is empty:
   • Inform user: "本地文档不完整，建议运行 /sync-crate-skills makepad --force 更新文档"
   • Still answer based on SKILL.md patterns + built-in knowledge
3. If reference file exists, incorporate its content into the answer

Key Patterns

1. Basic Hover Animation

<Button> {
    text: "Hover Me"

    animator: {
        hover = {
            default: off

            off = {
                from: { all: Forward { duration: 0.15 } }
                apply: {
                    draw_bg: { color: #333333 }
                }
            }

            on = {
                from: { all: Forward { duration: 0.15 } }
                apply: {
                    draw_bg: { color: #555555 }
                }
            }
        }
    }
}

2. Multi-State Animation

<View> {
    animator: {
        hover = {
            default: off
            off = {
                from: { all: Forward { duration: 0.2 } }
                apply: { draw_bg: { color: #222222 } }
            }
            on = {
                from: { all: Forward { duration: 0.2 } }
                apply: { draw_bg: { color: #444444 } }
            }
        }

        pressed = {
            default: off
            off = {
                from: { all: Forward { duration: 0.1 } }
                apply: { draw_bg: { scale: 1.0 } }
            }
            on = {
                from: { all: Forward { duration: 0.1 } }
                apply: { draw_bg: { scale: 0.95 } }
            }
        }
    }
}

3. Focus State Animation

<TextInput> {
    animator: {
        focus = {
            default: off

            off = {
                from: { all: Forward { duration: 0.2 } }
                apply: {
                    draw_bg: {
                        border_color: #444444
                        border_size: 1.0
                    }
                }
            }

            on = {
                from: { all: Forward { duration: 0.2 } }
                apply: {
                    draw_bg: {
                        border_color: #0066CC
                        border_size: 2.0
                    }
                }
            }
        }
    }
}

4. Disabled State

<Button> {
    animator: {
        disabled = {
            default: off

            off = {
