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:
3. Inform user: "本地文档不完整，建议运行 /sync-crate-skills makepad --force 更新文档"
4. Still answer based on SKILL.md patterns + built-in knowledge
5. 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 = {
                from: { all: Snap }
                apply: {
                    draw_bg: { color: #0066CC }
                    draw_text: { color: #FFFFFF }
                }
            }

            on = {
                from: { all: Snap }
                apply: {
                    draw_bg: { color: #333333 }
                    draw_text: { color: #666666 }
                }
            }
        }
    }
}
