And for the explosions around you use random

pawn Код:

new
    i,
    Float: X,
    Float: Y,
    Float: Z;
GetPlayerPos(playerid, X, Y, Z);
for( ; i != 10; ++i) { // 10 explosions
    CreateExplosion(
        X + (random(2) ? (random(10) + 10.0) : (-(random(10) + 10.0))),
        Y + (random(2) ? (random(10) + 10.0) : (-(random(10) + 10.0))),
        Z, 0, 5.0);
}

You could also create any object, like a circle with the trigonometric functions
