1. CSE4MOD Final Bot Navigation Paul Taylor 2009

2. Last Week JumpSpot Do Bots jump to or from these? Doors Without the door actor With the door actor

3. Advanced Doors Triggered Doors – Using a Trigger Switch Using a Door actor as your mover Set the trigger to match your switch. – Bots should be able to use the switch to get through the door

4. Lifts Three actors we will require: – Mover Same as a door, this is the physical representation of the lift – LiftCenter This is where the bots stand on the lift (roughly) – LiftExit Used to set the exit frame for Bots (roughly)

5. Mover InitialState – StandOpenTimed Mover will wait till player is on the lift Only works on triggered lifts – BumpOpenTimed Mover will wait till player is touching Works on Un-triggered lifts

6. LiftCenter LiftTag – This should be the Tag of the Mover, linking the actors with the physical lift. LiftTrigger – Set only when the lift is triggered, matches the switch used

7. LiftExit LiftTag – This should be the Tag of the Mover, linking the actors with the physical lift. SuggestedkeyFrame – Associated the keyframe with when the bots should exit the lift

8. Ladders Ladders are created with Ladder Volumes – The default setting of bAutoPath creates a nav point at the top and +40 at the bottom – You need to rotate these two so that they point towards the wall, so bots will face that way!

9. Advanced Pathing Sort of...

10. AssaultPaths These guys define paths towards objectives – Can be split between attack and return bReturnOnly bNoReturn Manual Path weighting – Priority sum-of-factor ObjectiveTag – xBlueFlagBase, xRedFlagBase, etc

11. Position and PathTags Position Property – Position0 then Position1, etc, then goal When chaining assaultPaths, you can use the PathTag property to set allowed path(s) A straight one-way chain is created using the position property

12. Defence & Sniping Points These guys are just part of the UnrealScriptedSequence actor You must face the actor in the proper direction – Yes bots will snipe at a wall!

13. Defence & Sniping Points In deathmatch they just specify points for bots to get a good view of players – bSniping this allows the point to be used as a sniper position – bRoamingScript allows the bot to roam around the area after reaching it – bNotInVehicle Bots will ignore the point if they are NOT in a vehicle – WeaponPreference bots need to be told to use the sniper rifle!

14. Vehicle Navigation There are three types – HoverPathNodes - Hover – RoadPathNodes – Road and Hover – FlyingPathNodes - Flying Land Vehicles must be connected to a white path The path must continue ALL-White to the bot’s objective – Alternatively set the GameObjective- >VehiclePathName to the nearest VehiclePathNode
