TLHPoE

Had the same problem, TGG resolved it.

GameData.getBlockRegistry(); GameData.getItemRegistry();

Well, you asked for a canon.

First you'll want to get a key to write in, then you'll need to write the melody that'll be iterating through out the song. After that, you'll just need to write it down in rounds.

I'm checking the keyboard in a player tick event on the client. package ttm.handler.event; import org.lwjgl.input.Keyboard; import ttm.Reference; import ttm.network.PacketMessage; import cpw.mods.fml.common.eventhandler.SubscribeEvent; import cpw.mods.fml.common.gameevent.TickEvent; public class FMLClientEventHandler { private boolean canJump = true; @SubscribeEvent public void playerTick(TickEvent.PlayerTickEvent event) { if(Keyboard.getEventKey() == Keyboard.KEY_SPACE) { if(canJump && Keyboard.getEventKeyState()) { new PacketMessage(Reference.PacketMessages.JUMP).sendToServer(); canJump = false; } else if(!canJump && !Keyboard.getEventKeyState()) { canJump = true; } } } }

Ok, the initial jump is on both sides, but it seems that motion only takes effect on the client side? I'm using packets so it's only going to be called on the server side. So should I also call it on the client side?

I should be on server side. The code I posted would be in my LivingJumpEvent, which I cancel with my own method, and then I call the event from a packet that was sent from the client. I'll go see if it's trying to set anything in the client.

I'm currently attempting to add double jumping, and I have everything else sorted but the actual jumping. I recently discovered the fact that you can add all the motion you want when the player is jumping, but the motion will only start to take place when he hits the ground. For example, while the player is air borne, I add 10 to motionY. It doesn't affect the player, until the player hits the ground. At that point, the player flies into the air like a rocket. Here's my code: double amt = 1; if(player.motionY < 0) { amt += (player.motionY * -1); } player.addVelocity(0, amt, 0);

I don't think you really need a custom item renderer to achieve this. On each render go through all of the slots (or atleast the slots you want to have the orange background), and check if they have your item. If they do, draw the orange slot.

Thanks everyone, TGG fixed it.

I'm calling the draw method during the post event of RenderGameOverlayEvent. http://pastebin.com/xQcsNvuv Here's a picture of the current situation (sorry about the craziness): Finally here's a picture of the textures: If the picture couldn't explain it, the transparent parts of the textured rectangles I'm drawing are being drawn as black areas instead of transparent areas.

Is there anyway to detect when an itemstack is put into and taken out of a slot? I can do both by using the putStack method in the Slot class, but doesn't get called when you just take an itemstack out of the slot. I've also tried comparing the inventory during the last tick and the inventory during the current tick. package ttm.handler.event; import java.util.HashMap; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import ttm.inventory.InventoryPlayerExtended; import ttm.util.LogUtil; import cpw.mods.fml.common.eventhandler.SubscribeEvent; import cpw.mods.fml.common.gameevent.TickEvent; import cpw.mods.fml.common.gameevent.TickEvent.Phase; public class FMLServerEventHandler { public HashMap<String, ItemStack[]> lastInventoryMap = new HashMap<String, ItemStack[]>(); @SubscribeEvent public void playerTick(TickEvent.PlayerTickEvent event) { if(event.phase == Phase.START) { EntityPlayer player = event.player; InventoryPlayerExtended inventory = InventoryPlayerExtended.forPlayer(player); if(lastInventoryMap.get(player.getDisplayName()) == null) { lastInventoryMap.put(player.getDisplayName(), inventory.inventory); } else { ItemStack[] lastInventory = lastInventoryMap.get(player.getDisplayName()); ItemStack[] currentInventory = inventory.inventory; for(int i = 0; i < 5; i++) { ItemStack lastStack = lastInventory[i]; ItemStack currentStack = currentInventory[i]; if(lastStack == null && currentStack != null) { LogUtil.info("EQUIP:" + currentStack.getDisplayName()); } else if(lastStack != null && currentStack == null) { LogUtil.info("UNEQUIP:" + lastStack.getDisplayName()); } else if(lastStack != null && currentStack != null) { if(!lastStack.equals(currentStack)) { LogUtil.info("LAST:" + lastStack.getDisplayName()); LogUtil.info("CURRENT:" + currentStack.getDisplayName()); } } } lastInventoryMap.remove(player.getDisplayName()); lastInventoryMap.put(player.getDisplayName(), inventory.inventory); } } } } For some reason, it prints "EQUIP: item.blah" and then "UNEQUIP: item.blah" in the next tick. Solved: The putStack method passes the itemstack that is put into it, and the onPickupFromSlot method passes the itemstack that is taken out of it.

What does the operation integer in AttributeModifier represent? I'm guessing that it's a mathematical operation done to a number, but what integers represent what operation?

I'm not sure whether it's not saving properly or not loading properly. I can put items into the slots, but when I close and reopen, it isn't there.

Ok, reflection isn't an option any more. Are there are updated tutorials for ASM?

I have my own Inventory class that I would like to replace the default inventory with. Is there a way with reflection to replace the type of the 'inventory' field in EntityPlayer with my class? If so, when should I be replacing it?

Anything?

Do you ever write to the NBT? If not, then that's your problem.

If an event is located in the cpw package, you register it in the FMLCommonHandler.instance().bus(), or if it's located in the minecraftforge package, you register it MinecraftForge.EVENT_BUS. There are some exceptions, like the ore gen events which are registered in the MinecraftForge.ORE_EVENT_BUS (something along those lines). I believe that most events that have the Living prefix are to be registered in the MinecraftForge.EVENT_BUS.

Yeah, the index is out of bounds so the list returns a null.

Is there a cap on how many slots a container can hold? The code should be adding about 62 slots, but the slots list has a size of 45 when it's done adding the slots. The weird part is that all of the slots are rendered, but if I try to click on one of the slots that are added after the first 45 are added, I crash with an NPE stating that the index is out of bounds.

Is there any other way to cover up the side bits of a gui without resorting to glScissor?

In your code, your beginning x position is 0, but mine starts at 298. How would I go about scaling 298?

Ok, how would I scale the x position though? ScaledResolutionT sr = new ScaledResolutionT(mc.gameSettings, this.width, this.height); int scale = sr.getScaleFactor(), scissorX = 298, scissorY = 20, scissorWidth = 256, scissorHeight = 438; GL11.glScissor(0, mc.displayHeight - (scissorY + scissorHeight) * scale, (scissorWidth + scissorX) * scale, scissorHeight * scale);
