Psychocrysma

Well, that was really helpful. Honestly, I haven't worked on Events in Java, so I'll try to find a way to make it work. Java is pretty much the same as C#, except for the link between classes and some code. Thank you for answering. If you have some code for the timer (AttackSpeed), I'd be very grateful. I have no idea how to make a timer honestly, except if there's a variant of the "Thread.Sleep" of C# (though it would make the application temporarily stop from doing anything since it is not Asyncronous )

Bump

Hi there! I'm new here, on both modding and on this forum. I don't have experience in Java programming (though I am quite experienced in C#) Anyway, to get to the point, I've been trying to make a weapon that would have a decreased knockback (less than normal) and a Speed bonus that, for example, decrease the number of ticks between each hit. Though I don't really need it, I would also like to know about fire aspect without the enchant, which I think I have once seen in Netherrocks. So, here's what I've tried to do using different resources (this forum post: http://www.minecraftforge.net/forum/index.php?topic=19914.0) and the decompilation of the Balkon Weapons Mod. All I've tried doesn't work. AttackSpeed.class import java.util.List; import net.minecraft.item.ItemStack; public class AttackSpeed { public static final String SPEED_NBT = "data:speed"; //20 ticks = 1 second /** * Call this onUpdate() in your Item WARNING: you should check for * !world.isRemote * * @param iStack * stack to update * @param maxCooldown * maximum speed */ public static void onUpdate(ItemStack iStack, int maxSpeed){ DataHelper.checkNBT(iStack); if(!DataHelper.verifyKey(iStack, SPEED_NBT)){ DataHelper.setInteger(iStack, SPEED_NBT, maxSpeed); } if(DataHelper.getInteger(iStack, SPEED_NBT) > 0){ DataHelper.decreaseInteger(iStack, SPEED_NBT, 1); } } /** * Checks for speed. Call it when your item needs to be used * * @param iStack * Stack to check * @param maxCooldown * Maximum speed * @return True if item's speed is zero, returns true and sets it to * maximum, otherwise false */ public static boolean canUse(ItemStack iStack, int maxSpeed){ DataHelper.checkNBT(iStack); if(DataHelper.getInteger(iStack, SPEED_NBT) > 0){ return false; }else{ DataHelper.setInteger(iStack, SPEED_NBT, maxSpeed); return true; } } /** * Call this addInformation() in your Item * * @param iStack * stack to update * @param info * speed text */ public static void displaySpeed(ItemStack iStack, List info) { DataHelper.checkNBT(iStack); if(DataHelper.getInteger(iStack, SPEED_NBT) > 0) { info.add("Speed: " + DataHelper.getInteger(iStack, SPEED_NBT)); }else { info.add("Speed: " + DataHelper.getInteger(iStack, SPEED_NBT)); } } } DataHelper.class import net.minecraft.item.ItemStack; import net.minecraft.nbt.NBTTagCompound; public class DataHelper { /** * Used for null-safety * * @param stack */ public static NBTTagCompound checkNBT(ItemStack stack){ if(stack.stackTagCompound == null){ stack.stackTagCompound = new NBTTagCompound(); } return stack.stackTagCompound; } /** * Shortcut for NBTTagCompound.hasKey() */ public static boolean verifyKey(ItemStack stack, String name){ return stack.stackTagCompound.hasKey(name); } public static void setInteger(ItemStack stack, String name, int value){ stack.stackTagCompound.setInteger(name, value); } public static int getInteger(ItemStack stack, String name){ return stack.stackTagCompound.getInteger(name); } public static void decreaseInteger(ItemStack stack, String name, int value){ if(getInteger(stack, name) > 0){ setInteger(stack, name, getInteger(stack, name) - value); } } public static void decreaseIntegerIgnoreZero(ItemStack stack, String name, int value){ setInteger(stack, name, getInteger(stack, name) - value); } public static void setString(ItemStack stack, String name, String value){ stack.stackTagCompound.setString(name, value); } public static String getString(ItemStack stack, String name){ return stack.stackTagCompound.getString(name); } public static void setBoolean(ItemStack stack, String name, boolean value){ stack.stackTagCompound.setBoolean(name, value); } public static boolean getBoolean(ItemStack stack, String name){ return stack.stackTagCompound.getBoolean(name); } public static void invertBoolean(ItemStack stack, String name){ setBoolean(stack, name, !getBoolean(stack, name)); } public static void setByte(ItemStack stack, String name, byte value){ stack.stackTagCompound.setByte(name, value); } public static byte getByte(ItemStack stack, String name){ if(!verifyKey(stack, name)){ setByte(stack, name, (byte)0); } return stack.stackTagCompound.getByte(name); } } ItemKatanaCreation.class import java.util.List; import com.psychocrysma.invasionblock.AttackSpeed; import com.psychocrysma.invasionblock.InvasionBlock; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.entity.Entity; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.ItemSword; import net.minecraft.item.Item.ToolMaterial; import net.minecraft.world.World; public class ItemKatanaCreation extends ItemSword { public ItemKatanaCreation(ToolMaterial katanaMaterial) { super(katanaMaterial); setUnlocalizedName("katanaCreation"); setTextureName(InvasionBlock.modid + ":" + getUnlocalizedName().substring(5)); setCreativeTab(CreativeTabs.tabCombat); } public static final int SPEED = 200; // 1 sec - 20 ticks. public void onUpdate(ItemStack iStack, World world, Entity entity, int dataInt, boolean dataBoolean) { if(!world.isRemote) { AttackSpeed.onUpdate(iStack, SPEED); } } public ItemStack onItemRightClick(ItemStack iStack, World world, EntityPlayer player) { if(AttackSpeed.canUse(iStack, SPEED)) { player.motionY++; } return iStack; } } I have also recovered this code, which I don't know how to use: import net.minecraft.entity.SharedMonsterAttributes; import net.minecraft.entity.ai.attributes.BaseAttribute; import net.minecraft.entity.ai.attributes.RangedAttribute; public class WeaponAttributes extends SharedMonsterAttributes { public static final BaseAttribute IGNORE_ARMOR_DAMAGE = new RangedAttribute("weaponmod.ignoreArmour", 0.0D, 0.0D, 1.7976931348623157E308D); public static final BaseAttribute WEAPON_KNOCKBACK = new RangedAttribute("weaponmod.knockback", 0.4D, 0.0D, 1.7976931348623157E308D); public static final BaseAttribute ATTACK_SPEED = new RangedAttribute("weaponmod.attackSpeed", 0.0D, -1.7976931348623157E308D, 1.7976931348623157E308D); public static final BaseAttribute RELOAD_TIME = new RangedAttribute("weaponmod.reloadTime", 0.0D, 0.0D, 1.7976931348623157E308D); public static final BaseAttribute WEAPON_REACH = new RangedAttribute("weaponmod.reach", 0.0D, 0.0D, 1.7976931348623157E308D); } I hope you can help me understand something in it. I think it would be useful to lots of people
