double ballBonus = PokeballTypeHelper.getBallBonus(getType(), this.thrower, p2, this.mode);

double a = (3 * hpMax - 2 * hpCurrent) * pokemonRate * ballBonus / (3 * hpMax) * bonusStatus;
double b = Math.round(Math.pow(255.0D / a, 0.25D) * 4096.0D) / 4096.0D;
b = Math.floor(65536.0D / b);
if (b != 0.0D) {
for (int i = 0; i < 4; i++) {
int roll = new Random().nextInt(65536);
if (roll <= b) {

It could be possible to return the result of 0 from the getBallBonus() function when the ball is thrown outside of battle (which is either a state in the EntityPokeBall.Mode property of Mode.full or Mode.battle or is read through the boolean isBattleThrown - I'm a decent programmer but I'm not used to java classes, so I couldn't really track down which one was the most correct).

Though based on the calculation of b above from (255.0D/ a, 0.25D)... if a=0, which seems to be the result from a return of ballBonus = 0, this would end up throwing a divide by zero error. So it might have to just be an "if (this.mode = mode.full)" statement somewhere the stops the capture attempt if non in battle.

Having a 0.0D return value from the getBallBonus function doesn't seem to be an issue, as it is the case when using safari balls outside of the plains biome returns 0.0D, and this result just has the pokemon instantly pop out of the pokeball - exactly what I want for behavior.

So here is an example of what I think would work (need to get eclipse to actually compile the java) - this is based on CaptureSafariBall.class and CaptureLoveBall.class:

public double getBallBonus(EnumPokeballs type, sq thrower, EntityPixelmon p2, EntityPokeBall.Mode mode)
{
#This line gets the biome based on the pokemon's location
aav biome = p2.q.a(kx.c(p2.u), kx.c(p2.w));

#ADDED CODE- This line returns 0% if the mode = mode.full, which is the case of capture attempts not in a battle (based on the CaptureLoveBall.class code), and if another mode, the other checks on this class are evaluated.
if (mode == EntityPokeBall.Mode.full) {
return 0.0D;
}

#This line is the check for the biome to be plains (which is what aav.c stands for) and returns 150% chance
if (biome == aav.c) {
return 1.5D;
}

#This line returns 0% chance in all other cases
return 0.0D;
}
