FSUIPC: Lua Tutorial

Get Started Okay! In our first steps... we will accomplish several things at once
So let's open your Lua Library Reference and your editor. If you tabulated your Library reference, go to the GoFlight (gfd) section. On the first page you'll see a list of GoFlight modules. I best almost everyone has at least a GFP8 or GFT8. All of those Module names are Constant variables. 1. The first "command" we find on the next page is gfd.BlankAll(). Type that into your editor. 2. Move down the page until you find gfd.SetBright(model, unit, n). Here's our real introduction to Constants and Variables. Look at that command carefully and take note of the stuff in the ( )... model, unit, n Those are the parameters for the command. They indicate we need to put in values that represent those items. For model, we use the constants listed on the first page. If you have a GFT8, we'll use that. If not, try using GFP8. Go ahead and type in the following... gfd.SetBright(GFP8, unit, n) Now what's this "unit" thing? It's the number of your GF module. When computers count anything, they ALWAYS start with zero. Your trigger may be called button #1, but it's actually button #0 (zero). We are going to use the variable "unit" to represent the number zero, so add the new line in your code so it looks like this...
gfd.BlankAll() Our last parameter is "n". We won't be using a Constant or Variable, we are going to use a direct value of 15... gfd.SetBright(GFP8, unit, 15) No go back and "check your case". Meaning, make sure the correct letters are Upper or Lower case. Lua commands ARE CASE SENSITIVE!!! So far, all this does is blank all the GF modules and set there brightness to 15 (full). But there's a big difference between "setting the brightness" and "turning on a light". So let's do that. Go back to your reference and find the command gfd.SetLight(model, unit, id). Go ahead and enter that command. Your script should look like this...
gfd.BlankAll() Since we are using the constant GFP8 to tell FSUIPC which model to operate, let's change "model" to "GFP8". You can leave "unit" alone since we've already assigned unit to equal zero. But now we have a new parameter... id. This is the number of the light, on the GF module. Remember, everything starts at zero... so to change things up, let's make that a one. gfd.SetLight(GFP8, unit, 1) You've just written your very first Lua script. Now let's save that, with the filename "MyTestLua.Lua", into your FS/Modules directory. Now run your FlightSim and start a flight so we can open the FSUIPC GUI. If you have a spare button, make a button assignment (as shown below) with the control being "Lua MyTestLua". Now, when you press that button, it will run that Lua script.
And again, if you can, choose another unused button and assign it to "Lua Kill All". You should find a copy of the file "MyLuaTest.Lua" in the
FLG Tutorials folder. |
