I am attempting to slow down the speed of all entities within a specific range of the player. The method I am doing this is working, but is resulting in odd behavior (like arrows stopping suddenly in air and then rapidly updating their position, mobs visually oscillating, etc). Here is my current method:
List<Entity> entitiesToSlow = world.getEntitiesWithinAABB(Entity.class, AxisAlignedBB.getBoundingBox(player.posX - 5, player.posY - 5, player.posZ - 5, player.posX + 5, player.posY + 5, player.posZ + 5)); if(entitiesToSlow.size() > 0) { for(int i = 0; i < entitiesToSlow.size(); i++) { Entity e = entitiesToSlow.get(i); if(e instanceof EntityPlayer) { } else { double velx = (e.posX - e.prevPosX); double vely = (e.posY - e.prevPosY); double velz = (e.posZ - e.prevPosZ); if(velx != e.getEntityData().getDouble("slowX") || vely != e.getEntityData().getDouble("slowY") || velz != e.getEntityData().getDouble("slowZ")) { e.getEntityData().setBoolean("inSlowZone", false); } if(!e.getEntityData().getBoolean("inSlowZone") ) { double factor = 0.7D; e.setVelocity(velx * factor, vely * factor, velz * factor); e.getEntityData().setBoolean("inSlowZone", true); e.getEntityData().setDouble("slowX", velx * factor); e.getEntityData().setDouble("slowY", vely * factor); e.getEntityData().setDouble("slowZ", velz * factor); } } }Is this the best way of slowing down the speed of an entity by a specific factor if it's within a specific area of the player?

Please read about how events work.
An event simply runs when certain conditions are met; in this case it's when a potion is brewed.

I am attempting to animate my armor model. The model displays, but nothing is animated; the model just follows along the player.

I don't think I was specific enough. I want to make a new potion effect; I know how to add it to the item, but I have no idea of how to actually make the effect (if that makes sense).
-
I am trying to create a new potion, but I haven't been able to find any relevant information besides a tutorial with very little information. Could anyone explain to me the steps of adding in a new potion with a brewing recipe?

I've updated the OP with the other two files.

I have created a custom mob, but for some reason the default ModelBiped animations (walking, arms swinging, etc) are not displaying. Here are the appropriate files:

-
Thanks, I'll look into that! I might end up making a dummy dimension so I can do the file manipulation, but if I can't I'll just create a dynamic dimension.
-
I've attempted to implement that, but the world files appear to still be in use. Here's the modified code block:
if(future.exists()) { try { System.out.println("THIS FUTURE EXISTS, MOVING THE FUTURE IN"); //mc.displayGuiScreen(null); MinecraftServer allServers = MinecraftServer.getServer(); for (int i = 0; i < allServers.worldServers.length; ++i) { if (allServers.worldServers[i] != null) { WorldServer wServer = allServers.worldServers[i]; wServer.canNotSave = true; System.out.println(wServer.canNotSave); } } //mc.statFileWriter.readStat(StatList.leaveGameStat, 1); //mc.theWorld.sendQuittingDisconnectingPacket(); //ms.stopServer(); // mc.loadWorld((WorldClient)null); Thread.sleep(3000); CopyFile.moveMultipleFiles(future, worldFile); for(int i = 0; i < allServers.worldServers.length; ++i) { if(allServers.worldServers[i] != null) { WorldServer wServer = allServers.worldServers[i]; wServer.canNotSave = false; } } //FutureTravelMechanics.launchWorld(folderName, worldName, (WorldSettings)null); //ms.startServerThread(); //mc.launchIntegratedServer(folderName, worldName, (WorldSettings) null); } catch(Exception ex) { ex.printStackTrace(); } }What I'm trying to achieve is load in a version of the world file that I had previously modified. However, because the world files are in use, they cannot be moved unless minecraft is not using them. Is it possible that Minecraft is still reading from the world file, and thus why the files aren't moving?
-
What I want the server-side to do is to exit the world, then reload it after I move around files in the world folder.
-
Thanks for the input! I also was thinking of doing this as well, but wanted to check here to make sure I'm not just over-looking something.

This is the affected method:
public static void launchWorld(String folderName, String worldName, WorldSettings ws) { if(FMLClientHandler.instance().getClient().isSingleplayer()) { FMLClientHandler.instance().getClient().launchIntegratedServer(folderName, worldName, ws); } }And here is where I am calling this method:
if(future.exists()) { try { System.out.println("THIS FUTURE EXISTS, MOVING THE FUTURE IN"); mc.displayGuiScreen(null); mc.statFileWriter.readStat(StatList.leaveGameStat, 1); mc.theWorld.sendQuittingDisconnectingPacket(); ms.stopServer(); // mc.loadWorld((WorldClient)null); Thread.sleep(3000); CopyFile.moveMultipleFiles(future, worldFile); FutureTravelMechanics.launchWorld(folderName, worldName, (WorldSettings)null); //ms.startServerThread(); //mc.launchIntegratedServer(folderName, worldName, (WorldSettings) null); } catch(Exception ex) { ex.printStackTrace(); } }This is inside of a class that implements IPacketHandler. I'm guessing that this error is occuring because this is run on the server, which does not have an OpenGL instance. However, this code needs to run serverside; any suggestions?
-
Thanks for that great explanation! I should hopefully be able to get that implemented sometime soon!
-
That assumption won't work for me, but I'll look into the EntitySenses and canEntityBeSeen methods.
After experimentation, I've discovered that canEntityBeSeen does not use the direction that the entity is facing: It just raytraces from the entity to the target entity, and assumes it is seen. Is there a way to modify this to get it to work for my needs?
-
Hello. I am trying to detect whether a player is visible by an entity; I have fiddled with the Enderman code but to no avail, as that code only detects if the enderman is seen by the player. Is there a way to detect this?

Read up on it, and I managed to get it to work.

Thanks, I've managed to get a basic coremod that recognizes the class and method working. However, I cannot seem to figure out how to get the ASM part working. Here is my ClassTransformer:
package timeTraveler.core; import static org.objectweb.asm.Opcodes.FDIV; import static org.objectweb.asm.Opcodes.INVOKEVIRTUAL; import static org.objectweb.asm.tree.AbstractInsnNode.METHOD_INSN; import java.util.Iterator; import net.minecraft.launchwrapper.IClassTransformer; import org.objectweb.asm.ClassReader; import org.objectweb.asm.ClassWriter; import org.objectweb.asm.Label; import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.tree.AbstractInsnNode; import org.objectweb.asm.tree.ClassNode; import org.objectweb.asm.tree.InsnList; import org.objectweb.asm.tree.MethodInsnNode; import org.objectweb.asm.tree.MethodNode; public class TTClassTransformer implements IClassTransformer { @Override public byte[] transform(String arg0, String arg1, byte[] arg2) { //System.out.println(arg0); if (arg0.equals("aqz")) { System.out.println("********* INSIDE OBFUSCATED BLOCK TRANSFORMER ABOUT TO PATCH: " + arg0); return patchClassASM(arg0, arg2, true); } if (arg0.equals("net.minecraft.block.Block")) { System.out.println("********* INSIDE BLOCK TRANSFORMER ABOUT TO PATCH: " + arg0); return patchClassASM(arg0, arg2, false); } return arg2; } public byte[] patchClassASM(String name, byte[] bytes, boolean obfuscated) { String targetMethodName = ""; if(obfuscated == true) { targetMethodName ="a"; System.out.println("******** Using obfuscated method"); } else { targetMethodName ="onBlockPlaced"; System.out.println("******** Using unobfuscated method"); } //set up ASM class manipulation stuff. Consult the ASM docs for details ClassNode classNode = new ClassNode(); ClassReader classReader = new ClassReader(bytes); classReader.accept(classNode, 0); //Now we loop over all of the methods declared inside the Block class until we get to the targetMethodName "onBlockPlaced" // find method to inject into @SuppressWarnings("unchecked") Iterator<MethodNode> methods = classNode.methods.iterator(); while(methods.hasNext()) { MethodNode m = methods.next(); System.out.println("********* Method Name: "+m.name + " Desc:" + m.desc); int fdiv_index = -1; //Check if this is onBlockPlaced and it's method signature is (Lnet/minecraft/world/World;IIIIFFFI)I if ((m.name.equals(targetMethodName) && m.desc.equals("(Lnet/minecraft/world/World;IIIIFFFI)I"))) { System.out.println("********* Inside target method!"); // find interesting instructions in method, there is a single FDIV instruction we use as target //System.out.println("m.instructions.size = " + m.instructions.size()); InsnList toInject = new InsnList(); //TODO: NEED TO CONVERT THIS TO JAVA CODE TO INJECT //LINENUMBER 87 L0 //NEW timeTraveler/mechanics/BlockPlaceEvent //DUP //ALOAD 0 //ILOAD 2 //ILOAD 3 //ILOAD 4 //INVOKESPECIAL timeTraveler/mechanics/BlockPlaceEvent.<init> (Lnet/minecraft/block/Block;III)V //ASTORE 5 //L1 //LINENUMBER 88 L1 //GETSTATIC net/minecraftforge/common/MinecraftForge.EVENT_BUS : Lnet/minecraftforge/event/EventBus; //ALOAD 5 //INVOKEVIRTUAL net/minecraftforge/event/EventBus.post (Lnet/minecraftforge/event/Event;)Z //POP //L2 /* //To add new instructions, such as calling a static method can be done like so: // make new instruction list InsnList toInject = new InsnList(); toInject.add(new VarInsnNode(ALOAD, 0)); toInject.add(new MethodInsnNode(INVOKESTATIC, "mod/culegooner/MyStaticClass", "myStaticMethod", "()V")); // inject new instruction list into method instruction list m.instructions.insert(targetNode, toInject); */ AbstractInsnNode currentNode = null; AbstractInsnNode targetNode = null; @SuppressWarnings("unchecked") Iterator<AbstractInsnNode> iter = m.instructions.iterator(); int index = -1; //Loop over the instruction set and find the instruction FDIV which does the division of 1/explosionSize while (iter.hasNext()) { index++; currentNode = iter.next(); System.out.println("********* index : " + index + " currentNode.getOpcode() = " + currentNode.getOpcode()); //Found it! save the index location of instruction FDIV and the node for this instruction if (currentNode.getOpcode() == FDIV) { targetNode = currentNode; fdiv_index = index; } } System.out.println("********* fdiv_index should be 336 -> " + fdiv_index); if (targetNode == null) { System.out.println("Did not find all necessary target nodes!

ClassWriter writer = new ClassWriter(ClassWriter.COMPUTE_MAXS | ClassWriter.COMPUTE_FRAMES); classNode.accept(writer); return writer.toByteArray(); } }Any ideas? (Note: I'm following a tutorial, but it doesn't explain the actual ASM part very well).

Hello. I am looking into using a coremod to inject code into a class. After digging around a bit, I saw the Tweak class under the cpw package. I have a few questions: What exactly does the cpw Tweak class do, and is it a possible way for me to inject code into a class using something in Forge (possibly the tweak class, if that is what it does)?
-
@GotoLink, that seems to be the thing I want to do: However, I cannot seem to find a method or variable that I can use to check if the xp orb is colliding with the player or not.
-
I looked at those methods, and I didn't see anything that would help. I need to essentially change the amount of xp an EntityXPOrb gives you based on certain conditions: any ideas?

Nothing is printed when I pick up an XP orb.

Hello! I am trying to do something when the player picks up an XP orb. I am using the following Event code for detecting XP orbs:
@ForgeSubscribe public void onPlayerEntityInteract(EntityItemPickupEvent event) { System.out.println(""); if(event.entity instanceof EntityXPOrb) { System.out.println(" :D"); int xpAmt = ((EntityXPOrb)event.entity).getXpValue(); int amtOfEnhance = 0; if(event.entityPlayer.inventory.hasItem(TimeTraveler.expEnhance.itemID)) { ItemStack[] items = event.entityPlayer.inventory.mainInventory; for(int i = 0; i < 35; i++) { if(items[i].getItem() instanceof ItemExpEnhance) { amtOfEnhance++; } } } System.out.println(amtOfEnhance); int newXpAmt = (amtOfEnhance * 2) * (xpAmt); event.entityPlayer.experience = event.entityPlayer.experience + newXpAmt; } } }however, "
:D" never prints and amtOfEnhance does not print as well. Any idea? -
I'm using the UUID to identify each mob individually, otherwise you have eight Zombies but no idea which is which. I do realize that EntityIDs and UUIDs are different things. I want to despawn all entities and prevent any from existing unless it has the specific UUID (which is why i need to set the UUID; The EntityHandler uses the UUID and MobType to determine whether or not to despawn the entity) that is contained in my data storage.
-
I need to change it because I need to identify a mob based off of it. I need to do this so I can only let certain mobs spawn, IE despawn all mobs and then spawn certain ones with certain UUIDs and EntityName so I can track each individual one.

Adding a potion effect will not work for me, as I need this to affect ALL entities, not just living entities.
