# Animation Requirements Catalog — Modular Game Framework

**For: Animator / Technical Animator | UE 5.5–5.7 | GASP-Based**

This catalog lists every animation asset needed across all 135 blueprint systems, organized by system category, with trigger, type, body region, and GASP integration notes.

---

## How to Use This Catalog

1. **Montages** = Root motion or in-place split into sections with notifies
2. **BlendSpaces** = Parameter-driven blending (speed, direction, strafe angle)
3. **PoseAssets** = Single-frame poses for IK targets or overlay blending
4. **IK Rigs** = Procedural arm/leg positioning

**GASP Integration Rule:** All full-body locomotion animations route through [`ABP_GASP`](../CONTEXT.md:9). Systems notify GASP via dispatchers; GASP reads state variables and selects the correct animation.

---

## 1. Locomotion System (GASP Core — Extended, Not Replaced)

| Trigger | Asset Type | Body | Notes |
|---------|-----------|------|-------|
| `Idle` → `Walking` → `Jogging` → `Sprinting` | **BlendSpace** | Full | GASP core locomotion blend. Speed + direction + strafe angle as params. Extended by framework: extra sprint variant for exhaustion, injured walk variant |
| `Crouching` + moving | **BlendSpace** | Full | Crouch locomotion. Speed as param. Separate from standing blendspace |
| `Prone` / `Crawling` | **BlendSpace** or **Montage** | Full | Prone crawl. Slow. Forward only initially, with strafe variants |
| `Jump Start` / `Jump Loop` / `Jump Land` | **Montage** (3 sections) | Full | Jump with velocity-based land (soft/hard). Motion matching picks jump type |
| `Fall Loop` | **BlendSpace** | Full | Falling animation based on vertical velocity |
| `Land Soft` / `Land Hard` / `Land Roll` | **Montage** | Full | Velocity threshold determines land type. `OnLanded` dispatcher drives selection |
