Question about enemy ai

[Garak]

I'm working on a space shooter and I need to have the enemies have the ability to shoot at the player.
How can I make it so that an enemy ship is able to detect what angle to shoot at the player?

[na_th_an]

angle = ATAN ( (yP-yE) / (xP-xE) )

Where xP,yP is the player's pos.. and xE ,yE is the enemy's position.

Thanks! That code works.

[TheBigBasicQ]

care to understand the math behind it?

Code:

o <- enemy (xe, ye)
|\
|A\
|  \
|   \
|    \
|_    \
|_|____\
        o <- you (xp, yp)

       (yp - ye)
tanA = ---------
       (xp - xe)

and so,

A = ATN[(yp - ye) / (xp - xe)]

Better use ATAN2 in FB. No checks needed.
