I am now releasing version 7 of the FizX In-Game Tweaker Tool (see attached). The previous version was unable to display the saved content to the StartUp field while you were working on it in-game. It would only display content after you closed Future Pinball and restarted the table. That issue has been resolved. I recorded a short video of how the tweaker tool works (see link below). If you have tried TerryRed's version of the tweaker on some of his tables, this version is different. On this version, you can save values in the StartUp field and they will run automatically the next time you play the table. The table will initially load with the Default values which are saved in the script. You can always revert back to the default values if you don't like the changes you added to the StartUp field. The video explains it. Terry's versions also save each parameter to a separate register (of which there are 32). This version saves all the parameters to a single register (nvS13).
After I recorded the video, I decided to add the tweaker to JLou's demo table for version 112a to make sure it is easy to do. Then I decided to release it instead of the version I recorded in the video. The tweaker code in both tables is identical.
If you want to add the tweaker to your table, search the script for "FizX Tweaker Start" and copy the entire section down to "FizX Tweaker End" and paste it into your table. Repeat the search until you don't find anymore sections. Be sure to read the notes at the beginning of the script. You need to carefully look at the "FizX Tweaker End" of the first section. Some parameters are included in the tweaker and some are not. Options that are included are listed above the "End Sub" that is close to the "FizX Tweaker End" flag. Note that the "SlingShotThreshold" option was moved above the flipper section inside the tweaker. The "SwingAngle" field for the main flippers was moved below "End Sub" because it is not included in the tweaker. It should be clear to you when you look at it.
This code can be adapted to other Future Pinball applications where you need to save the values of numeric parameters. In fact, Gimli and I put together a Lighting In-Game Tweaker Tool that will be released on the Avatar table. I included an Excel file in the download that I used to help calculate the 2 digit values that are needed. It might be useful for future development or if you want to understand how it works.
The download has a "script_FizXv112.vbs" file that needs to be saved to your scripts folder (C:\Games\Future Pinball\Scripts). The file "TweakerClean7.zip" needs to remain unzipped and saved in the same folder as the table.
This version of the tweaker seems finished to me. Please provide feedback if you want new versions.
