Applet by James Macgill, based on code by Andrae Muys
Use the options across the top of the applet to select a side, strength and range of influence for a unit.
Click on the map to place the unit.
Repeat or press clear.
This is a very rough implementation with very few features, I'll be adding more to it shortly.
If your interested then this file contains a copy of everything. : influence.zip
There's a lot that could be done here, if you have any suggestions then drop me a line or bring it up in comp.ai.games
Go to the A* Demo.
