I need those who have mastered or at least have an idea on how to work Model animations.

 

I made this mob which has "chicken" styled robot legs, and I implemented animation methods from ModelBiped. I have very small knowledge as to how to work on methods such as these:

 

this.LLegTop.rotateAngleX = MathHelper.cos(par1 * 0.6662F) * 2.0F * par2 * 0.5F;
  this.LLegMiddle.rotateAngleX = MathHelper.cos(par1 * 0.6662F) * 2.0F * par2 * 0.5F;
  this.LLegBottom.rotateAngleX = MathHelper.cos(par1 * 0.6662F) * 2.0F * par2 * 2F;

 

Here is the entire Model of the mob:

The legs are the problem right now.

Here's how it's supposed to look in-game:

And here's how it turned out:

The problem is that you haven't used a "child" relationship between parts, so they won't stay connected (unless you do a lot of math to re-position them).  The vanilla Minecraft biped model has only one part for each arm and each leg so it doesn't have to worry about this.  As soon as you make it multiple parts you can't just copy the way Minecraft does it -- instead you have to organize your model into child parts.

 

The ModelRenderer had a method for this called addChild().  You can add children to children as well.  The way you should organize it is that the top of the leg should be the child of the body, then the middle of the leg a child to the top of the leg, the bottom of the leg a child to the middle of the let, etc.  Then if you rotate the top of the leg, all the other parts will rotate properly with it.

 

I have a tutorial on this: http://jabelarminecraft.blogspot.com/p/complex-entity-models-including.html

 

The difficult part is that the children have a position that is relative to the parent, rather than to the overall model origin.  So after you add the child you will need to adjust the rotation point by subtracting the parent's rotation point.

 

Once you have the model properly set up with child parts, animation becomes much easier.  You can do things like wave the hand while also raising the arm and it will all work together.

 

Hope that helps.

      REVIEW OF THE BEST BITCOIN RECOVERY TEAM - MUYERN TRUST HACKER

      By andreygagloev · Posted

      When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )

      corail tombstone fire crash

      By Ugdhar · Posted

      You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

      corail tombstone fire crash

      By belzabel · Posted

      So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
