I had massive, massive problems with MCAnimator and animations. And not just in the "animate when" situation, but in a "does bad bad things and will crash the game" kind of way. I was never able to fix it and instead rebuilt things using a standard quadruped.

NovaViper · May 27, 2015

So, don't use MCAnimator at all then?

Draco18s · May 27, 2015

Some people swear by it, but as I wanted to have an animation only play when my mob was walking, I did what looked like the only way to play and stop animations, which caused Concurrent Modification Exceptions. Which no one was able to help me figure out.

So.

Yeah. Don't use MCAnimator. Good news, the model it creates is very easy to turn into a ModelBase. You need to refactor some function names and work out the euler rotations from the quaternions (but as you created the model using eulers...) but it's pretty much a 1:1 port.

NovaViper · May 27, 2015

Well, I wanted to use the model from MCAnimator to have animations when my entity jumps and lands and swims in water, thats why I used MCAnimator. Since I can't use it, is there any alternative?

Draco18s · May 27, 2015

Quick and easy? Not that I know of.

NovaViper · May 27, 2015

Shoot, thanks anyway.

Draco18s · May 27, 2015

Yeah, I'd given it a shot after I'd seen a lot of praise on these forums, but it turns out no one uses it for animation. Surprise, surprise.

NovaViper · May 27, 2015

Huh, didn't know that. Hey.. I got a question also, the author of Dragon Mounts uses something similar to MCAnimator like these

https://github.com/ata4/dragon-mounts/tree/master/src/main/java/info/ata4/minecraft/dragon/client/model

Maybe I can use this?

Draco18s · May 27, 2015

They custom built their animator.

public class DragonAnimator { ... }

NovaViper · May 27, 2015

Hm.. Have any tips on how to build an animator like this one or similar to it?

Draco18s · May 27, 2015

Haven't the faintest.

NovaViper · May 27, 2015

Welp, time to go for trial and error

NovaViper · May 27, 2015

Hey, what about this program called Blender?

N247S · May 27, 2015

Hey,

I was strugling too with most programs like MCAnimator etc.. I don't know blender, you should try it to see if its working or not.

But the Link that helped me out (for Entities at least) is this:

http://jabelarminecraft.blogspot.nl/p/complex-entity-models-including.html

He explains some neat tips and tricks on how to create your own animatons.

NovaViper · May 27, 2015

Hey, it looks like someone did use blender with some help from MCAnimator and techne to create this

http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/modification-development/2328217-blender-for-minecraft-modeling-anonmine-models

May 27, 2015

From what I hear It's better to code models and animations yourself, but I've been struggling with entity animation as well as soon as I tried to do it.

NovaViper · May 27, 2015

Yeah, it's pretty useful and easier to use for visualization, but should I at all, use it? Even just to use it to get the numbers to model them using the method jabelar recommends us using for animation?

May 27, 2015

It's useful for visualization, but I find modeling in techne to be a pain sometimes. Don't you?

Edit: Lol, I forgot we were talking about MCAnimator. It is a little easier and is useful for visualizing of animation, but still a pain to model in in my opinion.

NovaViper · May 27, 2015

Definitely, especially when it comes to the addChild methods for animations

May 27, 2015

I know right? I never did figure that addChild stuff out...

NovaViper · May 27, 2015

Here, I used this tutorial to master the addChild methods: http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571589-modding-animation-guide

I also did trial and error and finally got them correct.. but still need help with advanced animations

N247S · May 27, 2015

I do recommend it indeed, because it supports childmodelParts. But keep in mind that it aint perfect.

I experianced an slight offset in the dimensions. but it shouldnt be disturbing if you don't need a model to be moving punctual at the single degree.

(I only discoveres it cause I wanted a model to move exactualy across certain lines)

If you need an example, I made an animated tileEntity in my mechanicalCraftingTable mod.(Link below) Feel free to take a look at it.

Keep in mind though, my mod and the tutorial is for mc 1.7.10!

So you probably need to dig into the .jons files etc. But apart from that, it should look similar.

Anyway good luck, and please share the results! Im curious.

Cool. I think next time I work with entities I'll try to do it in Java. I tried to work with animation in Java but I couldn't figure out how to convert from degrees to radians. This tutorial helps though, http://jabelarminecraft.blogspot.ca/p/introduction-first-of-all-to-understand.html. In fact, I didn't even know they were called radians before today, all I knew was somehow I needed to convert degrees to the stupid huge decimal number format thingy.

NovaViper · May 27, 2015

Lol and yeah, I've used that tutorial also, but I couldn't get the animation to flow smoothly
