[1.11.2] Capabilities

How can I get Forge Capabilities from a player using

onRenderTick(TickEvent.RenderTickEvent event) {

to render kindoff gui, drawString for example.

Minecraft.getMinecraft().player is now EntityPlayerSP not EntityPlayerMP, so NBT also doesn't work. Maybe I should sync it somehow?

Anyway, Im trying use Capabilities, but on client side also it's empty.

 

Should I use other event? Which one then? I want to render specified drawString/drawTexturedModalRect when player is holding right mouse button on specified item.

Previously I was able to do that using NBTs and Item#onUpdateTick, then checking on client onRenderTick if player is holding specified item and draw value from player nbt.

That's a short explanation of what I want to do.

 

Thanks for advice!

Entity::getCapability allows you to get a specified capability data. As EntityPlayer(and EntityPlayerSP) are child classes of Entity you can use this method just fine.

Minecraft.player was never EntityPlayerMP as EntityPlayerMP is a multiplayer player entity.

NBT has nothing to do with getting the data of a capability.

Capabilities are common and are present on both client and server. What exactly have you tried?

You can simply check that the active itemstack contains the desired item(if the item has a use duration) or if the currently selected itemstack contains the desired item and the right mouse button is pressed down.

Capabilities are common yes, aka both on the server and client, however, the capability data is only saved on the server. As per official documentation.

Yeah, it was EntityClientPlayerMP, my bad.

I know. I mean, I used NBT before, when I was able to. But now NBT is different on Client and Server.

For example Im setting nbt string in Item#onUsingTick. Then I want to read it from Minecraft.getMinecraft().player.getEntityData() (because TickEvent.RenderTickEvent doesn't have any entity or player field), and there is no such string.

 

So I decided to use new DataStorage. I've tried to change TickEvent.RenderTickEvent to LivingEntityUseItemEvent.Tick, but error appear on bindTexture, "java.lang.RuntimeException: No OpenGL context found in the current thread.". So Im done at the moment.

Exactly. So how am I able to read any data from client? Should I use Custom Packets for such a thing?

All redering must be done on the rendering thread. You need to use render-related events. You can still access capabilities and such from the render thread just fine.

If the data you need is only present on a server then yes, you need a custom packet to sync the data to the client.
