Mod
X Player API
Realistic biomechanical character animations, glTF multi-track support, dual visual proxies, and drop-in replacement for player_api.
A high-fidelity player visual and animation management mod for Luanti that upgrades the default player model with glTF multi-track animations, realistic athletic biomechanics, and a stylized futuristic character skin while maintaining 100% backward compatibility with canonical 6-bone skins and armor.
Features
- Dual-Model Visual Proxies & Observer Filtering: Seamlessly serves modern
.glbmodels to Luanti 5.17.0+ clients and fallback.b3dmodels to older clients on the same server viaset_observersnetwork culling, with 0.08 rad bone override throttling. - Pure Native B3D Option: Optional zero-proxy mode (
x_player_api.pure_native_b3d = true) applying B3D meshes directly to the native player entity with hardware-smooth client prediction for stand, walk, mine, and walk_mine. - Multi-Track glTF Support (
.glb): Native multi-track named animation channels for Luanti 5.17.0+ with GPU skeletal blending. - Athletic Locomotion (
walk,sprint): Realistic gait kinematics with transverse pelvic yaw, double-bounce vertical oscillation, forward torso lean, 3D curved arm swings, and head gaze stabilization. - Diaphragmatic Breathing (
stand): Organic respiration cycle with ribcage expansion, asymmetrical resting stance, and secondary arm breathing movement. - Dynamic Kinetic Strike (
mine,walk_mine): Athletic full-body mining action with torso coiling anticipation, downward core drive, explosive impact snap, and elastic recoil recovery. - High-Definition Character Texture: Clean futuristic style featuring ceramic composite armor plating, carbon fiber tech suit, and glowing electric cyan power core.
- Declarative Equip Sound Registry: Dynamic sound playback and equip animation montages when switching weapons, tools, and items, with group fallbacks, direct item registration (
register_equip_sound), and custom item definition overrides. - Agnostic Extensible API: Flexible registries for custom consumables (
register_consumable), action rules (register_action_rule), and dynamic multi-track animations (play_action,register_model). - 100% Skeletal Compatibility: Retains canonical 6 bones (
Body,Head,Arm_Left,Arm_Right,Leg_Right,Leg_Left) plusCapechannels for compatibility with skins and armor. - Seamless
player_apiDrop-in Override: When enabled, fully replaces and overrides the defaultplayer_apimethods, model registrations, and globalstep logic while transparently resolving modpaths. - Native 3D Wield Items: Ephemeral child entity rendering with visual = 'wielditem' attached to Arm_Right, supporting custom anisotropic wield_scale, pivot translation drift compensation, and 3d_armor compatibility.
