Is there a way to call on a function to spawn a mod?

world.spawnEntity(entity, other stuff)

That does not exist is it spawnenityinworld ?

My bad. There are 3 steps to spawning an entity.

Step 1: declare the entity EntityChicken derp = new EntityChicken(world);

Step 2: set the position and stuff (I don't know the exact name but it's something like) derp.setPostionAndSomethingElse()

Step 3: now all the data has been set, so just do world.spawnEntityInWorld(derp);

 

NOTE: before spawning the entity, do if(!world.isRemote) otherwise it'll spawn 2 entities. 1 that behaves normally, and 1 that doesn't move

 

Took me a couple hours to figure this out so I hope I saved you some time

Here's some of my code, this one spawns my custom mob when i place a block. I don't know how to make a mob spawn in the way that cows or sheep do but there are plenty tutorials for that on youtube.

 

public int onBlockPlaced(World world, int par2, int par3, int par4, int par5, float par6, float par7, float par8, int par9)

    {

if (!world.isRemote){

    EntityCitizen entitycitizen = new EntityCitizen(world);

    entitycitizen.setPosition( par2 +2, par3, par4);

    {

   

    world.spawnEntityInWorld(entitycitizen);

    }

    }

    return par9;

    }
