Asteroids Bullets Directions?

hiya all,

I am wondering how do you do Bullets directions when the spaceship move around all angle and fire at the same time.

I was thinking of using rotateimage for spaceship and bullets but no it doesnt work.

does anyone could up with simple solutions?

cheers

it is 2D game by the way

You could 'prerotate' the images: copy the original ship's image 36 times, and rotate them with steps of 10.
For the projectiles, you could use cos and sin to calculate it's position:

x# = x# + (cos(angle#) * speed#)
y# = y# + (sin(angle#) * speed#)
DrawImage bullet, x#, y#

DrawImage ship, ship_x, ship_y, angle# / 10

Thanks B32 =)

cheers
