This AI control is easier to implement than the previous one. Instead of creating a path to follow, we will simply indicate a coordinate our AI Unit has to move to. You need 2 entities to do this :
- a TagPoint entity to indicate where you want to AI Unit to go to
- an AreaTrigger entity to trigger the AI Unit movement and actually get him walking towards the TagPoint entity
|
Start placing the 3 entities on the map :
- In the RollupBar AI menu add the TagPoint entity
- In the RollupBar Entity menu add the AreaTrigger entity ( see screenshot on the right)
- Add a new AI Unit in the map (see previous tutorials if you don't know how to do so)
Now you have your 3 entities on the map, select your AreaTrigger entity and create a new Flow Graph (once again, see previous tutorial if you don't know how to do this). In the Flow Graph, you're going to have to add 3 different flow objects :
- Right click and pick Add Node > Misc > Start
- Right click and pick Add Node > AI > AIGotoSpeedStance
- Right click and pick Add Node > Entity > EntityPos
- Connect the Start entity Output to the AIGotoSpeedStance Sync input as shown below
- Connect the EntityPos pos output to the AIGotoSpeedStance pos input as shown below
- Select your TagPoint entity in your map then right click on the EntityPos flow box and choose Assign Selected Entity
- Select your AI Soldier in your map then right click on the AiGotoSpeedStance flow box and choose Assign Selected Entity

If you did all these actions correctly, click on the
AI/Physics button in the bottom part of Sandbox2 editor window to see your entity move to the TagPoint.
