From efcabd31a1a3fe453b45bbe3481f562fe4cf1ad2 Mon Sep 17 00:00:00 2001 From: SpaceToad Date: Sun, 8 Jun 2014 11:58:55 +0200 Subject: [PATCH] More work on lumberjacks. RPC now support entity messages. Robots now support item synchronization between client and server. Lumberjack now use a variable tool. for #1869 --- .../builders/TileAbstractBuilder.java | 4 +- common/buildcraft/builders/TileArchitect.java | 2 +- .../builders/TileBlueprintLibrary.java | 7 +- common/buildcraft/builders/TileBuilder.java | 6 +- .../network/BuildCraftChannelHandler.java | 1 + .../core/network/PacketHandler.java | 6 + common/buildcraft/core/network/PacketIds.java | 1 + .../core/network/PacketRPCEntity.java | 61 +++++++++ .../buildcraft/core/network/RPCHandler.java | 122 ++++++++---------- .../buildcraft/core/render/RenderRobot.java | 10 +- .../buildcraft/core/robots/EntityRobot.java | 25 ++++ .../robots/boards/BoardRobotLumberjack.java | 7 +- .../buildcraft/energy/TileEnergyEmitter.java | 10 +- .../tests/testcase/TileTestCase.java | 4 +- 14 files changed, 174 insertions(+), 92 deletions(-) create mode 100755 common/buildcraft/core/network/PacketRPCEntity.java diff --git a/common/buildcraft/builders/TileAbstractBuilder.java b/common/buildcraft/builders/TileAbstractBuilder.java index ac865b8f..11f0c579 100755 --- a/common/buildcraft/builders/TileAbstractBuilder.java +++ b/common/buildcraft/builders/TileAbstractBuilder.java @@ -60,7 +60,7 @@ public abstract class TileAbstractBuilder extends TileBuildCraft implements ITil @RPC (RPCSide.SERVER) private void uploadBuildersInAction (RPCMessageInfo info) { for (BuildingItem i : buildersInAction) { - RPCHandler.rpcPlayer(this, "launchItem", info.sender, i); + RPCHandler.rpcPlayer(info.sender, this, "launchItem", i); } } @@ -124,7 +124,7 @@ public abstract class TileAbstractBuilder extends TileBuildCraft implements ITil public void addBuildingItem(BuildingItem item) { buildersInAction.add(item); - RPCHandler.rpcBroadcastPlayers(this, "launchItem", item); + RPCHandler.rpcBroadcastPlayers(worldObj, this, "launchItem", item); } public final double energyAvailable() { diff --git a/common/buildcraft/builders/TileArchitect.java b/common/buildcraft/builders/TileArchitect.java index 11a9a4f0..b6d072de 100644 --- a/common/buildcraft/builders/TileArchitect.java +++ b/common/buildcraft/builders/TileArchitect.java @@ -146,7 +146,7 @@ public class TileArchitect extends TileBuildCraft implements IInventory, IBoxPro @RPC (RPCSide.SERVER) public void handleClientSetName(String nameSet) { name = nameSet; - RPCHandler.rpcBroadcastPlayers(this, "setName", name); + RPCHandler.rpcBroadcastPlayers(worldObj, this, "setName", name); } @RPC diff --git a/common/buildcraft/builders/TileBlueprintLibrary.java b/common/buildcraft/builders/TileBlueprintLibrary.java index 52f1b78b..edd9166b 100644 --- a/common/buildcraft/builders/TileBlueprintLibrary.java +++ b/common/buildcraft/builders/TileBlueprintLibrary.java @@ -219,15 +219,14 @@ public class TileBlueprintLibrary extends TileBuildCraft implements IInventory { BlueprintBase bpt = ItemBlueprint.loadBlueprint(getStackInSlot(1)); if (bpt != null && uploadingPlayer != null) { - RPCHandler.rpcPlayer(this, "downloadBlueprintToClient", - uploadingPlayer, bpt.id, bpt.getData()); + RPCHandler.rpcPlayer(uploadingPlayer, this, "downloadBlueprintToClient", + bpt.id, bpt.getData()); uploadingPlayer = null; } } if (progressOut == 100 && getStackInSlot(3) == null) { - RPCHandler.rpcPlayer(this, "requestSelectedBlueprint", - downloadingPlayer); + RPCHandler.rpcPlayer(downloadingPlayer, this, "requestSelectedBlueprint"); progressOut = 0; } } diff --git a/common/buildcraft/builders/TileBuilder.java b/common/buildcraft/builders/TileBuilder.java index 5dffc06d..bf274001 100644 --- a/common/buildcraft/builders/TileBuilder.java +++ b/common/buildcraft/builders/TileBuilder.java @@ -447,7 +447,7 @@ public class TileBuilder extends TileAbstractBuilder implements IMachine, IFluid if (!worldObj.isRemote) { if (i == 0) { - RPCHandler.rpcBroadcastPlayers(this, "setItemRequirements", + RPCHandler.rpcBroadcastPlayers(worldObj, this, "setItemRequirements", null, null); iterateBpt(false); } @@ -726,10 +726,10 @@ public class TileBuilder extends TileAbstractBuilder implements IMachine, IFluid stack.stackSize = 0; } - RPCHandler.rpcBroadcastPlayers(this, "setItemRequirements", + RPCHandler.rpcBroadcastPlayers(worldObj, this, "setItemRequirements", ((BptBuilderBlueprint) bluePrintBuilder).neededItems, realSize); } else { - RPCHandler.rpcBroadcastPlayers(this, "setItemRequirements", null, null); + RPCHandler.rpcBroadcastPlayers(worldObj, this, "setItemRequirements", null, null); } } diff --git a/common/buildcraft/core/network/BuildCraftChannelHandler.java b/common/buildcraft/core/network/BuildCraftChannelHandler.java index 6b661279..ec8617ac 100755 --- a/common/buildcraft/core/network/BuildCraftChannelHandler.java +++ b/common/buildcraft/core/network/BuildCraftChannelHandler.java @@ -40,6 +40,7 @@ public class BuildCraftChannelHandler extends FMLIndexedMessageToMessageCodec break; } + case PacketIds.RPC_ENTITY: { + ((PacketRPCEntity) packet).call(player); + + break; + } + case PacketIds.RPC_PIPE: { // TODO: RPC pipes are not used right now.
