Making Straight Particle

Using cos, sin, and for, make 10 particles in a straight line in the direction that the player looks at. Because I want some code example.

 

you could do something like

PHP:

for($i=0;$i < 10;$i++)
$level->addParticle(new PARTICLE($player->add(0,1.62)->add($player->getDirectionVector()->multiply($i))));//PARTICLE is whatever particle class you want to use


 

Try devise some code by yourself for that. It isn't that hard to do it as it seems... You won't take anything from it if I put the finished code here.

 

I tried many times but I don't quite understand it yet about using sin cos.

 

can't make with using sin cos ? plz

 

I'm not sure this will work, if don't try add PI/2 or 3PI/2 in function's arguments

PHP:

$lenght = 20;
for($i = 0; $i < $lenght; $i++) {
   $x = $i * cos(deg2rad($player->getYaw()));
   $z = $i * sin(deg2rad($player->getYaw()));
   $y = $player->getY() + 1;
}

 

just getYaw() is left, isn't it? or is getYaw() get's player's looking side? I can't try code now so can you tell me

 

it's code for direction with const Y
