PHP Code:

for (A; B; C)
{
  D;
} 


In this sequence, A is run once. Then as long as the condition B is true, C and D will run continuously. For example:

PHP Code:

for (temp.i = 0; temp.i < 3; temp.i ++)
{
  echo(temp.i);
} 


… is a simple counter. It starts by setting temp.i = 0, and then as long as temp.i < 3, then it will run temp.i ++ (adding 1 onto temp.i) and then echoing the result.

Whats the diffrence between player.x and vecx?

player.x is a variable containing the player's X position on the level. vecx() is a function which determines horizontal vectors.

is random a event?

No, random(min, max) is a function which returns a random value which is somewhere between the given minimum and maximum values.
