Solved How do I make sure my mobs don't suffocate when spawned?

Using this code, I can spawn a few wolves around a target player

Code:java

if (Integer.valueOf(args[1]) <= configValInt("max-wolves")) {                           
    Player target = Bukkit.getServer().getPlayer(args[0]);                               
    Location targetLoc = target.getLocation();                                           
 
    Random r = new Random();                                                             
 
    for (int i = 0; i < configValInt("max-wolves"); i++) {                               
        // Random x and z value within a 10x10 square                                   
        int xr = r.nextInt(10) + 1;                                                     
        int zr = r.nextInt(10) + 1;                                                         
        int direction = r.nextInt(2) + 1;                                               
 
        if (direction == 1) {                                                           
            target.getWorld().spawnEntity(targetLoc.subtract(xr, 0, zr), EntityType.WOLF);
        } else if (direction == 2) {                                                     
            target.getWorld().spawnEntity(targetLoc.add(xr, 0, zr), EntityType.WOLF);   
        }                                                                                 
    }                                                                                   
}                                                                                        

The only problem is that in hilly/mountainous environments and tight spaces the wolves, more often-than-not, spawn inside the terrain... and suffocate. How can I figure out a safe place for my wolves to spawn?

Also, how can I change the state of the spawned wolves from passive to angry?

 

Use

Code:

getHighestBlockYAt(XCoord, ZCoord);

to get the highest block so that they can't spawn into terrain. They might spawn in a cave still though, but they won't suffocate.

 

I did find that function last night, but when I implemented it

Code:java

int safeY = target.getWorld().getHighestBlockYAt((int) (targetLoc.getX()), (int) (targetLoc.getZ()));
 
if (direction == 1) {                                                                               
    target.getWorld().spawnEntity(targetLoc.subtract(xr, 0, zr).add(0, safeY, 0), EntityType.WOLF); 
} else if (direction == 2) {                                                                       
    target.getWorld().spawnEntity(targetLoc.add(xr, safeY, zr), EntityType.WOLF);                   
}                                                                                                    

my wolves fell from the sky and died. Also only one spawned instead of the amount (1-5) specified in the command.

 

WhosDaMan Odd, I don't have Java on my PC atm, so I can't test anything, might want to wait a bit for someone else. Sorry!
