Minecraft Forums

I am very new to modding and I need help with a few things that I cant find 1.7 tutorials on (I have watched all the 1.7.2 modding tutorials on YouTube). I would like to learn how to make a gun that can fire bullets and reload ect. I tried exsparimenting with the item.bow class but I cant get it to work.

I need help soon

1. i'm not a moderator, but i'm pretty sure you shouldn't bump your posts.

2. there's lots of gun mods out there, copy the code and edit it to your liking.

how can I get other mods code?

Quote from awesomeguy129

download them and import them into eclipse. I'm not sure how to do that though....

k thanks I will try this

If a mod author does not give their source out, it is technically illegal to decompile and import their source code into your development environment.

There are plenty of gun tutorials online, one is on the MinecraftForge wiki.

I have code from my ItemGun, I will not give you the entity unless you need it. Atm, here's the actual Item

  this.setMaxDamage(100);
}

public void onCreated(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer) {
 
 
 
}

Random ran = new Random();
private int capacity = 12;//Clip size

    public EnumAction getItemUseAction(ItemStack par1ItemStack)
    {

  }
    }
}

  {

  }

  {
  
   //Vec3 vec3 = par3EntityPlayer.getLookVec();
   //double x = par3EntityPlayer.posX + vec3.xCoord;
   //double y = par3EntityPlayer.posY + vec3.yCoord;
   //double z = par3EntityPlayer.posZ + vec3.zCoord;
   //double d0 = (ran.nextInt(5) - 2.5) / 100;
         //double d1 = (ran.nextInt(5) - 2.5) / 100;
         //double d2 = (ran.nextInt(5) - 2.5) / 100;
        
  
   par1ItemStack.getTagCompound().setInteger("clip", par1ItemStack.getTagCompound().getInteger("clip") - 1);
   par2World.playSoundAtEntity(par3EntityPlayer, "random.explode", 0.5F, 1F);
   for (int i = 0; i < 7; i++) {
    EntityBullet pellet = new EntityBullet(par2World, par3EntityPlayer, EnumBulletType.TYPE_INT_PELLET)
    par2World.spawnEntityInWorld(pellet);
   
   
   }
  }
 
 

  return par1ItemStack;
}

}

The code has been modified, was at least twice this size. That should start you somewhere..

Thanks so much this is what I was looking forI would also like to have the entity codeEdit - I tried this code but am getting a few errors with RustCore and EnumBulletType

Just change:
RustCore to your main mod item, and you can remove that EnumBulletType parameter, I no longer use it.

Here's the entity + render

Entity

package com.neuro.rust.game.entity;

import java.util.List;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.entity.Entity;

public class EntityBullet extends EntityThrowable
{

public EntityBullet(World par1World)
    {
        super(par1World);


    }

public void entityInit() {
}

    public EntityBullet(World par1World, EntityLivingBase par2EntityLivingBase, double d, double e)
    {
        super(par1World, par2EntityLivingBase);
        this.setLocationAndAngles(par2EntityLivingBase.posX, par2EntityLivingBase.posY + (double)par2EntityLivingBase.getEyeHeight(), par2EntityLivingBase.posZ, par2EntityLivingBase.rotationYaw - 285, par2EntityLivingBase.rotationPitch - 90);
    }


    public EntityBullet(World par1World, double par2, double par4, double par6)
    {
        super(par1World, par2, par4, par6);
    }

    protected float getGravityVelocity()
    {
        return 0.003F;//Change this for bullet curvature downwards over flight time.
    }

    /**
     * Called when this EntityThrowable hits a block or entity.
     */
    protected void onImpact(MovingObjectPosition par1MovingObjectPosition)
    {
     Material material = this.worldObj.getBlockMaterial(par1MovingObjectPosition.blockX, par1MovingObjectPosition.blockY, par1MovingObjectPosition.blockZ);
     byte damage = 4; 

        if (par1MovingObjectPosition.entityHit != null)
        {

         par1MovingObjectPosition.entityHit.hurtResistantTime = 0;
            par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), (float)damage);
        }

        String n;
        float s;
        if (material == Material.anvil || material == Material.iron) {
         n = "random.anvil_land";
         s = 0.3F;
        }
        else if (material == Material.wood || material == Material.rock) {
         n = "dig.wood";
         s = 0.875F;
        }
        else {
         n = "dig.cloth";
         s = 0.875F;
        }

        this.worldObj.spawnParticle("smoke", this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D);
        this.worldObj.playSoundAtEntity(this, n, s, rand.nextFloat() + 1F);

     if (material == Material.glass || material == Material.ice || material == Material.plants || this.worldObj.getBlockId(par1MovingObjectPosition.blockX, par1MovingObjectPosition.blockY, par1MovingObjectPosition.blockZ) == Block.torchWood.blockID) {
     if (rand.nextBoolean()) this.setDead();
     this.worldObj.destroyBlock(par1MovingObjectPosition.blockX, par1MovingObjectPosition.blockY, par1MovingObjectPosition.blockZ, true);
     }

        if (!this.worldObj.isRemote)
        {
            this.setDead();
        }
    }
    boolean var1 = true;
    public void onUpdate() {
     super.onUpdate();

     if (var1) {
            for (int i = 0; i < 5; ++i)
            {
             double d0 = (rand.nextInt(5) - 2.5) / 100;
             double d1 = (rand.nextInt(5) - 2.5) / 100;
             double d2 = (rand.nextInt(5) - 2.5) / 100;

                this.worldObj.spawnParticle("smoke", this.posX, this.posY, this.posZ, this.motionX / 18  + d0, this.motionY / 18 + d1, this.motionZ / 18 + d2);
            }
            this.worldObj.spawnParticle("flame", this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D);
            var1 = false;
     }
    }
}

ALSO, Add this to the item code! It is used by the renderer to get a custom texture without it being from an item.

    public void registerIcons(IconRegister par1IconRegister)
    {
        this.iconPellet = par1IconRegister.registerIcon("yourModIdHere:entity/bullet");
        this.itemIcon = par1IconRegister.registerIcon(this.getIconString());
    }

/\ Don't forget to create iconPellet if it doesn't already exist in ItemGun


And finally, the renderer:

I am sure you know how to register the entity with the renderer?
