ok here is my bullet type it looks good to me but it creates an error saying type global initializers must be constant.

Type Bullet
Field x,y,direction,speed
Global Bullet_List:TList = CreateList()

Function create(x,y,direction,speed)
temp_shot:Bullet= New Bullet
temp_shot.x=x
temp_shot.y=y
temp_shot.direction=direction
temp_shot.speed=speed
ListAddLast(Bullet_List,temp_shot)
EndFunction

Function draw()
Local temp_shot:Bullet=Bullet(Bullet_List.last())
SetColor 235,200,124
DrawOval 32,32,x-16,y-16
EndFunction

Function update()
Local temp_shot:Bullet=Bullet(Bullet_List.last())
temp_shot.draw()
' make the x and y move
temp_shot.x:+ speed*Cos(direction)
temp_shot.y:+ speed*Sin(direction)
EndFunction

Function destroy()
ListRemove(Bullet_List,Self)
EndFunction

EndType
