I'm having another problem. I have been able to figure out how to get the enemy to rotate and face the direction the player is.
But i'm having trouble working out how to make the enemy follow the player or move toward the player like a magnet if the player is within range.

if GetSpriteExists ( 500 )
spriteraycast ( getspritexByOffset ( 1 ), getspriteyByOffset ( 1 ), getspritexByOffset ( 500 ), getspriteyByOffset ( 500 ) )
rem Angle enemy to point at player
xoffset# = GetRayCastX() - GetSpriteXByOffset ( 500 )
yoffset# = GetRayCastY() - GetSpriteYByOffset ( 500 )

rem Adjustment for angles outside -90 to +90
if xoffset# < 0
bias = 180
else
bias = 0
endif

enemyangle# = atan ( yoffset#/xoffset# ) + bias
SetSpriteAngle ( 500, enemyangle# -90 )
endif

Exploding zombies, classic

Point sprite code:


Move sprite code:


Move sprite up:


The main issue here I think was it helps to use the atanfull command rather than atan.


this.mess = abs(sin(times#))
