Particles

How can I make Particles randomly fly around a player?

 

My idea is to use RepeatingTask, set it around 3 ticks is optimal. On every tick, spawn a new particle around Player, and saves the last particle spawn coordinate for next particle. I think this can achieve that "fly" animation.

 

I want to make random circle particles. (I know how to add particles and so on)

 

PHP:

$r = 1; //Radius, the distance of the particle and the player
$diff = 30; //The smaller, the smoother the transition effect
for($theta = 0; $theta <= 360; $theta += $diff){
    $x = $r * sin($theta);
    $z = $r * cos($theta);
    //Add up player x, z with above $x, $z and spawn the particle
}

This is the code for Circular Coordinate Calculation. In every for loop, new $x diff anf $z diff is calculated, just add the diff x and z with Player's x, z and it should be working fine. I think this is the one you looking for

EDIT: This is the basic one 2d Circle Calculation, remember to lift up Player's Y to show it around player. And I havent test this code, but the concept of that code is correct

 

Wow the Math looks simpler

 

Oh but wait.. Your code has problem. In Sine and Cosine, 30° is actually no difference with 150° as sin(30) an sin(150) are both 1/2, so when $theta in the for loop is the (value <= 90)+180 then those X positions would be same.

 

You forgot to think of Z

When theta = 30,
diffX = sin(30) = 0.5
diffZ =cos(30) = 0.866

When theta = 150,
diffX = sin(150) = 0.5
diffZ = cos(150) = -0.866 <- negative

Hence, the position won't be the same. In a circle loop, its possible to get same value of each x and z for more than twice. Check the cosine and sine graph and you will know it

Math xD

 

Oh forgot the cosine property xdd
