Multball Code:
Here's how I code my multiball. This is basic and will help you keep track of the ball(s). This assumes 2 kickers and 3 ball multiball. It also assumes you have to hit a target down to initiate multiball.
Objects you will need (correctly named):
Kicker1
Kicker2
Ballrelease
Mutiballtarget
Multiballlight
Drain
Dim Ballslocked, Ballsinplay
Sub Kicker1_Hit()
If Lock1.State=1 Then 'Locklight
Lockball
End If
If Tilt=False Then
Addscore 1000
Playsound""
End If
Else
Kicker1.Kick 135,15
End Sub
Sub Kicker2_Hit()
If Lock2.State=1 Then 'Lock light
Lockball
End If
If Tilt=False Then
Addscore 1000
Playsound""
End If
Else
Kicker2.Kick 135,15
End Sub
So, if lock is lit when the kicker is hit, call the lockball sub. Otherwise kick the ball back out. If the game isn't tilted then add the score and play any sounds.
Sub Lockball()
Ballslocked=Ballslocked+1
Ballrelease.Createball
Ballrelease.Kick 90,12
If Ballslocked=2 Then Multiballlight.State=1
Mutiballtarget.Isdropped=False
End If
If Tilt=False Then
Addscore 1000
Playsound ""
End If
End Sub
We call this sub to lock the ball, add 1 to the ballslocked variable, and kick out another ball in the plungerlane. No need to change ballsinplay because you're locking one and kicking another out.
We also check for ballslocked, because if you have 2 ballslocked, turn on the multiball light and raise the target.
Sub MutiballTarget_Hit()
If Multiballlight.State=1 Then
Kicker1.Kick 135,15
Kicker2.Kick 135,15
Ballsinplay=ballsinplay+2
Lock1.State=0
Lock2.State=0
End If
End Sub
If the multiball target is hit with the light on then kick the balls out, reset the lights, and expect 2 extra balls in play.
Other things you need:
In the "Newgame" or Startgame sub you will need: Ballsinplay=1
Ballslocked=0
In your "Nextball Sub you need:
Ballsinplay=1
Ballsinplay=0 (when you start your bonus routine, then when you kick out a new ball you have 1 ball in play).
In your "Drain_Hit" Sub you need: (Example).
Sub Drain_Hit()
Ballsinplay=Ballsinplay-1
If Ballsinplay=0 Then
Start your bonus or whatever.
End If
End Sub
This keeps track of Multiball for you.
Hope this helps any budding tablemakers. Obviously you can get much more elaborate with jackpots, and relocking balls during multiball, etc. But this is a basic routine to keep track of 3 balls.
