projectiles?
BlitzPlus Forums/BlitzPlus Beginners Area/projectiles? A simple way is to do the following:
create a 'type' like this:
then when your creature/player presses the fire button you do something like this:
okay once bullets are created we need to manage them and make sure they do what they are meant to do, so in your core loop / main loop you would have a call to the following function every frame:
create a 'type' like this:
type bulletobject field x#,y#,z# ;position in the world of the bullet field angle# ;direction bullet flies in field speed# ;overall speed of the bullet field lifetime ;you may want your bullets to disappear after a while if they don't hit anything, or go off the screen end type
then when your creature/player presses the fire button you do something like this:
if keyhit(57)<>0 then ;space bar was pressed (fire button) bullet.bulletobject=new bulletobject bullet\x=;player position / gun muzzle position in the world bullet\y=;as for bullet\x bullet\z=;if you are doing a 2d game then this is not needed bullet\speed=;what ever speed you want your bullets to fly at bullet\angle=;whatever angle the player is facing in endif
okay once bullets are created we need to manage them and make sure they do what they are meant to do, so in your core loop / main loop you would have a call to the following function every frame:
;I assume your game code looks like this to some extent repeat ;get player input, update player stuff... UpdateBullets() until keydown(1)<>0 or gameover function UpdateBullets() for Bullet.BulletObject=each BulletObject Bullet\X=Bullet\X+Bullet\Speed*Cos(Bullet\Angle) Bullet\Y=Bullet\Y+Bullet\Speed*Sin(Bullet\Angle) ;check if the bullet hit anything here ;check if the bullet left the screen or should be removed and so so next end function
