Hello,

I'm new to mods development for Minecraft Bedrock and could use some help with an issue I am having.

I created a new mob (cow_fire) using the Vanilla cow files. I made my modifications and everything works great except that I cannot assign an animation controller. When I include the following lines of code in my 'cow_fire.entity.json' file, my new mob does not render (it becomes invisible and so does its spawn egg).

"animation_controllers": [
{ "flame": "controller.animation.cow_fire.flame" }
],

I have a file called 'cow_fire.animation_controllers.json' in the animation_controllers folder of my resource pack. Its contents are as follows (adapted from the blaze mob animation controllers):

{
"format_version" : "1.10.0",
"animation_controllers" : {
"controller.animation.cow_fire.flame" : {
"initial_state" : "default",
"states" : {
"default" : {
"transitions" : [
{
"flaming" : "!query.is_swimming"
}
]
},
"flaming" : {
"particle_effects" : [
{
"effect" : "charged_flames"
}
],
"transitions" : [
{
"default" : "query.is_swimming"
}
]
}
}
}
}
}

(I am trying to have the cow always be on fire except when it is swimming.)

Note that if I remove all transitions and leave just one default state with nothing in it, the mob still won't render. If I remove the animation_controller reference from the 'cow_fire.entity.json' file, the mob renders just fine.

What am I doing wrong? Any help would be GREATLY appreciated!
