Solved Skin validation?

Fixing up a KitPvP plugin and the server seems not to be able to read the file for a skin that I provided. I am using file_get_contents() with a .dat file for the skin. The server has reached the file path but something about it must be wrong. I am using this to spawn a Human entity and upon its creation the server crashes with this:

Any help I can get with Skin->validate() and Human::deserializeSkinNBT()? I'm pretty sure the issue is here is with the file I'm using, but I've seen it done before. Do I need to use a .png instead?

 

Saving the raw skin data should work just fine. May we see the parts of your code that save and load skins?

 

It's directly from a file in the plugin's directory. Envoy extends Human

I hope this isn't a facepalm - this is my first time experimenting with this part of PM.

Code:

$entity = new Envoy($this->getPosition()->getLevel(), new CompoundTag(" ", [
    new ListTag("Pos", [
        new DoubleTag("", $x),
        new DoubleTag("", $y),
        new DoubleTag("", $z)
    ]),
    new ListTag("Motion", [
        new DoubleTag("", 0),
        new DoubleTag("", 0),
        new DoubleTag("", 0)
    ]),
    new ListTag("Rotation", [
        new FloatTag("", 0),
        new FloatTag("", 0),
    ]),
    new ShortTag("Health", 30),
    new CompoundTag("Skin", [
        new StringTag("Data", file_get_contents(KitPvP::getInstance()->getDataFolder() . "skins/holding_chest.dat")),
        new StringTag("Name", "Standard_Custom")
    ]),
]), $this);

 

What is the content of that file (holding_chest.dat)? (how did you create it)

Why are you using NBT directly instead of PMMP's entity methods?

 

holding_chest.dat was a 128 x 128 .png file which I converted.

Don't know - I'm not fully familiar with messing with entities yet, I'm doing it the way I know how. If there is a better way I could look into that. The spawning of this entity is in a task. Do you need to see the Envoy class file or the entirety of the file I posted a snippet of above (DropPoint class), to get a better idea of how I'm doing this?

 

How was it converted? There probably was an error in that conversion process.

If your Entity extends PocketMine's Entity class (or Human, because it also has a skin and such) then you are offered various methods for manipulating it.
