I know there are ways to spawn groups of AI with set behavior and waypoints. But I feel that it would be much better and easier to have a feature which allows you to place a unit with a waypoint in the editor and then place a trigger where he would spawn only when it is activated.
- Place AI
- Give command
- Add spawn trigger module.
This would simplify many not-so-experienced scripters mission editing lives. It would also boost the missions performances immensly if you plan to have alot of AI.
