Effects in Animations

Effects in Animations ​

Sometimes it is much easier to use particles or sounds in animation rather than in animation controller. Animations can have effects in them, such as:

• Particles
• Sounds

Particles ​

Minecraft Particles can be used in entity animations. For example, the phantom has an animation which emits the minecraft:phantom_trail particle constantly. Let's try to add a particle to our entity's attack animation.

"particle_effects": {
	"flames": "minecraft:mobflame_emitter"
}

Here we defined a shortname for particle that we are going to use.

You can find a list of particles here or here.

Sounds ​

If you want to use a sound, you need to define it too. You can get sounds at ZapSplat.

"sound_effects": {
	"meow": "mob.cat.meow"
}

Adding Effects to Animation ​

You can add particles or sounds to your animation mainly or in Blockbench.

Mainly ​

You need to add the following to your animation:

"particle_effects": {
    "0.0": {
        "effect": "flames",
        "locator": "" //You need to add a locator in your model
    }
}

"sound_effects": {
    "0.0": {
        "effect": "meow"
	}
}

You can call more than one particle at the same time:

"particle_effects": {
    "0.0": [
        {
            "effect": "particle_1",
            "locator": "locator_1"
    	},
	{
            "effect": "particle_2",
            "locator": "locator_2"
    	}
    ]
}

{
	"format_version" : "1.8.0",
	"animations" : {
		"animation.sheep.grazing" : {
			"animation_length" : 2.0,
			"loop" : true,
			"particle_effects": {
                "0.0": {
                    "effect": "flames",
                    "locator": "body"
                }
            },
			"sound_effects": {
    			"0.0": {
    			    "effect": "meow"
				}
			},
			"bones" : {
				"head" : {
					"position" : {
						"0" : [ 0.0, 0.0, 0.0 ],
						"0.2" : [ 0.0, -9.0, 0.0 ],
						"1.8" : [ 0.0, -9.0, 0.0 ],
						"2" : [ 0.0, 0.0, 0.0 ]
					},
					"rotation" : {
						"0.2" : {
							"post" : [ "180.0 * (0.2 + 0.07 * math.sin(q.key_frame_lerp_time * 1644.39))", 0.0, 0.0 ],
							"pre" : [ 36.0, 0.0, 0.0 ]
						},
						"1.8" : {
							"post" : [ 36.0, 0.0, 0.0 ],
							"pre" : [ "180.0 * (0.2 + 0.07 * math.sin(q.key_frame_lerp_time * 1644.39))", 0.0, 0.0 ]
						}
					}
				}
			}
		}
	}
}

In Blockbench ​

First let's add a locator for our particle. Go to "Edit" section, select a group, right-click and choose "Add Locator":

Rename it and move where you want.

Then go to "Animate" section, choose an animation and click on a magic stick icon:

Now click "+" to open menu and specify the data:

You can attach a sound to animation the same way.

Now save your animation and launch the game!

Offscreen Updating ​

You can set "should_update_bones_and_effects_offscreen" to true inside entity rp scripts for particle and sound effects to update offscreen, by default both of them will stop playing if the entity isn't being rendered on display.

"scripts": {
	"should_update_bones_and_effects_offscreen": true
}
