Installation

To install and use the Game Logic Framework in your VPX table, you will need to download the lastest vpx-glf.vbs script and include it in your table script

vpx-glf.vbs

Global Script Required Settings

The GLF requires a few global settings to function correctly.

GLF Game Timer

Add a timer object to your vpx table called Glf_GameTimer. Set it to Enabled with an Interval of -1ms.

GLF Table Collection

Create the following collections using the vpx collections manager (F8).

glf_lights
glf_switches
glf_slingshots
glf_spinners

Global Script Settings

  • cGameName must be set to your table name
  • BallSize, BallMass, tnob, lob and gBot must be set
  • tablewidth and tableheight must be set.

Example 

Const cGameName = "MyAwesomeGame"
Const BallSize = 50         'Ball diameter in VPX units; must be 50
Const BallMass = 1          'Ball mass must be 1
Const tnob = 6              'Total playable balls (Balls in Trough)
Const lob = 2               'Total non playable balls (Captive Balls)
Dim gBot                    'Collection used for ball tracking
Dim tablewidth: tablewidth = Table1.width
Dim tableheight: tableheight = Table1.height

Configure Devices

You'll need an entry point to configure your devices and enable modes. Create a sub called ConfigureGlfDevices

Sub ConfigureGlfDevices
    'Device confguration goes here.
End Sub

Adding Hooks into GLF

You need to add these calls into to your table event subs.

Table Init

Inside Table1_Init add your ConfigureGlfDevices sub call and Glf_Init()

Example

Sub Table1_Init()
    ConfigureGlfDevices()
    Glf_Init()
End Sub

Table Exit

Inside Table1_Exit add Glf_Exit()

Example

Sub Table1_Exit()
    Glf_Exit()
End Sub

Table Keys

Inside your Table1_KeyDown and Sub Table1_KeyUp Subs, add the Glf_KeyDown and Glf_KeyUp calls.

Example

Sub Table1_KeyDown(ByVal keycode)
    Glf_KeyDown(keycode)
End Sub

Sub Table1_KeyUp(ByVal keycode)
    Glf_KeyUp(keycode)
End Sub

Table Options

Inside Table1_Options add Glf_Options(eventId)

Example

Sub Table1_OptionEvent(ByVal eventId)
    If eventId = 1 Then DisableStaticPreRendering = True

    Glf_Options(eventId)

    If eventId = 3 Then DisableStaticPreRendering = False
End Sub
