Throwing A Grenade

Hi all Greetings from Sweden!

This time i've really tried before posting but after a while i get tired and eger to finish todays goals and start gaming some "real" games (Rainbow Six) =)

Well i think theres more people out there who needs to now the following aswell.

The thing is that i want to throw a grenade. I have got it to work as far as the grenade is moving +1 for ever 0.350th of a sekund and depending on how strong the throw is it goes different far away from its origin (the players hand). The nade also has collission checks and it explodes after 3sec after it has landed on ground. So im almost happy with it.

But now i want it to go in a realistic bow (dont know the english word). Anyway this is my code (the not working one):

Function Update_Grenade()

  For ThisNade.NadeType = Each NadeType

    If ThisNade\State = 1 Then;If its moving
      If (MilliSecs() + 350.0 > ThisNade\MovingTimer#) Then
(ThisNade\ThrowPower#/10.0)
                ThisNade\X# = EntityX(ThisNade\Ent)
        ThisNade\Z# = Float((ThisNade\Z# + ThisNade\MovingTimer#))
        ThisNade\Y# = Float((ThisNade\Y# + (ThisNade\Z# * ThisNade\Z#)))
                PositionEntity ThisNade\Ent,ThisNade\X#,ThisNade\Y#,ThisNade\Z#  
        ThisNade\MovingTimer# = MilliSecs()
      EndIf

      If Abs(EntityX(ThisNade\Ent,1)) > 10000 Then		FreeEntity ThisNade\Ent
        Delete ThisNade
      ElseIf Abs(EntityY(ThisNade\Ent,1)) >10000 Then
        FreeEntity ThisNade\Ent				Delete ThisNade						ElseIf Abs(EntityZ(ThisNade\Ent,1)) > 10000 Then
          FreeEntity ThisNade\Ent				  Delete ThisNade					ElseIf ThisNade\ThrowPower# <= 0.0 Then            
          ThisNade\ThrowPower# = 0.0             
          ThisNade\DetonateTimer#  = MilliSecs()
          ThisNade\State = 2      
        EndIf
    ElseIf ThisNade\State = 2 Then;Has stopped
      TranslateEntity ThisNade\Ent,0,Gravity#,0
      If MilliSecs() > (ThisNade\DetonateTimer# + 3000.0)Then
  DetonateNade(ThisNade\Ent)  
      EndIf
    EndIf
 
  Next

End Function

Sry if the code dont match on web...
Can anyone help?
Thanks!
