Shooter problems....

Hmm
Seem to be having a problem with my code. When I run it, the bullets stop about 2 seconds after they have been fired.
Will I have to use types or something?

;;;;;;;;;;;;;;;;;;;;;

While Not KeyHit(1)

updatebullet


If KeyDown (203) Then TurnEntity player,0,0.75,0 ;turn player left
If KeyDown(205) Then TurnEntity player,0,-0.75,0 ;turn player right
If KeyDown(200) Then playerspeed=playerspeed+0.1 ;speed up player
If KeyDown(208) Then playerspeed=playerspeed-0.1 ;slow down player
If KeyDown(30) Then MoveEntity player,0,0.5,0 MoveEntity cam,0,0.5,0 ;move player up
If KeyDown(44) Then MoveEntity player,0,-0.5,0 MoveEntity cam,0,-0.5,0 ;move player down

If playerspeed>3 Then playerspeed=3
If playerspeed<1 Then playerspeed=1


If KeyHit(45) Then

spark=CreateSphere(10)
EntityAlpha spark,0.7
EntityColor spark,255,100,20
PositionEntity spark,EntityX#(player),EntityY#(player),EntityZ#(player)
TurnEntity spark,0,EntityYaw(player),0

EndIf

MoveEntity player,0,0,playerspeed
MoveEntity spark,0,0,playerspeed+2
sparktimer=sparktimer+1
smoothcam(piv,player,70)

if entitycollided(player,nodec)
print "<< You got a node! >>"
nodes=nodes+1

endif

Well, i'd use types for bullets :) Means you can have more than one bullet on-screen with little hassle. About your bullet stopping. It might be becaus your trying to fire more than one, and the bullet is getting reset back to it's start position.
Try this out. I know it probably isn't what your game does, but should give you an idea of what to do. Need to rush now, so i'll comment it when i get back :D

Arrow keys to turn and move, X or Z to shoot...i forget :D

Thanks, I really needed some help with this.
