Using the NDF Debugger

The debugger is very useful to check if the game evaluates your NDF code as you want.

First create a file test.ndf with the first exercise in <GameDirectory>\DataLight\effet\TestModding\
launch the game with the mod manager (Test MOD in Dev Mod)
Open the debugger with ALT + D
Open your .ndf file with "File", "Load fichier parNDF". Now select your test.ndf file
Add breakpoints (click at the left of the line numbers) where you want
Now Run (with F9). In the game, press CTRL+P and CTRL+D in order to launch the effect in the file.
When the game evaluates the line with breakpoint, it will stop.

If you want the game to evaluate the next lines, clic on "Step" (F8) or "Step Into" (F7).

By rolling your mouse over a variable or an accessor, you will be able to see their value.
