[1.12.2] Custom Player Capability

[FelipeMunhoz]

Can someone point me to where I went wrong?

I'm trying to add a new ability to the player, everything works fine,
but the data is not persisting!
Sorry for my english

Você só deve modificar os dados no servidor.

O que exatamente faz você pensar que os dados não estão persistindo (quais sintomas você está observando)?

There is a gui that displays the current cosmo

public class CosmoGUI {
	
	public static class GUIRenderEventClass {
		
		@SubscribeEvent(priority = EventPriority.NORMAL)
		public void onRenderGui(RenderGameOverlayEvent event) {
			if (!event.isCancelable() && event.getType() == RenderGameOverlayEvent.ElementType.EXPERIENCE) {			
				
				Minecraft mc = Minecraft.getMinecraft();
				mc.renderEngine.bindTexture(new ResourceLocation(Reference.MOD_ID+":textures/gui/cosmo_bar_overlay.png"));
				
				EntityPlayer player = mc.player;
				ICosmo cosmo = player.getCapability(CosmoProvider.COSMO_CAP, null);		
				
				int posX = event.getResolution().getScaledWidth() / 2 + 10;
				int posY = event.getResolution().getScaledHeight() - 45;
				
				//Retorna caso o player esteja no modo criativo
				if(player.isCreative())
					return;
			
				//Desenha a barra de cosmo na tela
				mc.ingameGUI.drawTexturedModalRect(posX, posY, 0, 0, 81, 5);				
				int barWidht = (int)((cosmo.getCosmo()/cosmo.getLimit())*81);				
				mc.ingameGUI.drawTexturedModalRect(posX, posY, 0, 5, barWidht, 5);
				
				//Desenha o texto com quantidade de cosmo atual e maxima
				int stringSize = ((cosmo.getCosmo()+" / "+cosmo.getLimit()).toString().length()*4);
				mc.fontRenderer.drawStringWithShadow((int)cosmo.getCosmo()+" / "+(int)cosmo.getLimit(), (posX+41)-(int)(stringSize/2), posY-8, -13421569);

After you've changed the data of the capability on the server you need to send the changes to the client so the client is aware of the change. GUIs are client side only.
