Brain frame nwn 3.3

What it does
This tool, BrainFrameNWN, allows you to construct scripts graphically using a flowchart-like display. Actions and decision points are represented as flowchart nodes connected by arrows, and the flowcharts can be nested, making complex behaviors easier to script. (It also makes reuse of script segments easy.) Once you've built your visual representations of the behaviors you want, the tool will automatically generate NWScript code for you.
