Server MoLang Reference

Titan extends Cobblemon’s MoLang with server-side execution through the server_molang keyframe type. This enables powerful scripting within ActionEffect timelines.

Particles

`q.particle_effect(id, pos, count, spread)`

Fallback Logic:

Check vanilla registry (minecraft:*)
If not found, use SpawnSnowstormParticlePacket (Cobblemon)
Render radius = spread * 2 (clamped 16-96 blocks)

Entity Conditions

`q.entity.is_user`

Type: Query Variable Returns: Boolean

Checks if the current entity context is the Titan (user) or a target.

Examples:

// In entity_particles keyframe
{
  "type": "entity_particles",
  "entityCondition": "q.entity.is_user == false",  // Only targets
  "effect": "cobblemon:impact_fire",
  "locators": ["target"]
}

// In animation keyframe
{
  "type": "animation",
  "animation": ["hurt"],
  "entityCondition": "q.entity.is_user == false"  // Target hurt anim
}

Usage: Filter entity particles/animations to targets only.

Temporary Variables

`t.*` Namespace

Store intermediate values for reuse within the same server_molang keyframe.

Examples:

// Store position
t.pos = q.position(0);
q.particle_effect('cobblemon:thunder_actorcloud', t.pos, 200, 8.0);
q.particle_effect('cobblemon:thunder_targetsparks', t.pos, 100, 5.0);

// Store calculated value
t.damage = q.move_damage * 1.5;
q.damage_all(t.damage);

// Multiple temp vars
t.x = q.position(1);
t.y = q.position(2);
t.z = q.position(3);

Scope: Single server_molang keyframe execution

Advanced Examples

Phase Enter Script

// Raichu Phase 3 Enter (raichu.json:63)
q.titan.apply_potion('minecraft:speed', 999999, 2);
q.titan.apply_potion('minecraft:strength', 999999, 1);
q.titan.apply_potion('minecraft:resistance', 999999, 1);
q.invoke_move('overcharge');
q.play_sound('minecraft:entity.lightning_bolt.thunder', 1.1, 0.9);

    "q.titan.apply_wither(2.0);",
    "q.play_sound('minecraft:entity.generic.explode', 1.0, 0.8);"
  ]
}

Layered Particle Effect

// Ceruledge Armor Oblivion final explosion
q.particle_effect('cobblemon:eruption_targetburst', q.position(0), 80, 10.0);
q.particle_effect('cobblemon:willowisp_actorwisp', q.position(0), 500, 12.0);
q.particle_effect('cobblemon:shadowball_actorcharge', q.position(0), 300, 9.0);
q.particle_effect('cobblemon:swordsdance_sparkle', q.position(0), 200, 8.0);
q.particle_effect('cobblemon:impact_ghost', q.position(0), 250, 7.0);
q.particle_effect('cobblemon:eruption_actorlava', q.position(0), 300, 8.0);

Execution Order

Within a server_molang keyframe, expressions execute sequentially in array order:

"expressions": [
  "t.pos = q.position(0);",              // 1. Store position
  "q.play_sound('...', 1.0, 1.0);",      // 2. Play sound
  "q.particle_effect('...', t.pos, ...);", // 3. Spawn particles (uses t.pos)
  "q.damage_all(50.0);"                  // 4. Deal damage
]

Performance Considerations

Particle Count - Keep under 300 per effect for client performance
Sound Layering - Limit to 3-4 simultaneous sounds
Temp Variables - Reuse expensive queries (q.position(0))
Expression Count - 5-10 expressions per keyframe is typical

Troubleshooting

Expressions Not Executing

Check:

Array format: "expressions": [...] not "expression": "..."
Semicolons at end of each expression
Quotes around strings
Commas between array elements

Particles Not Appearing

Check:

Particle ID correct (verify in Cobblemon bedrock repository)
spread large enough for render distance
Position valid (q.position(0) not NaN)

See: Particles & Visuals →

Damage Not Applying

Check:

q.damage_all() called within damage_obb keyframe expressions
Entities registered in OBB context (defined + telegraphed)
Damage value not 0
