14. Now comes the fun part! First, set up the special behavior modules in your object:

Code

    Behavior = SpecialPowerModule  ModuleTag_MountSpecialStarter     

     UpdateModuleStartsAttack    = Yes

        SpecialPowerTemplate        = SpecialAbilityHelmDefenderMount

     StartsPaused            = No

    SetModelCondition        = ModelConditionState:USER_6

    SetModelConditionTime        = 0.1

    End



Behavior = ModelConditionSpecialAbilityUpdate ModuleTag_MountSpecialUpdate  

    SpecialPowerTemplate    = SpecialAbilityHelmDefenderMount

    UnpackTime        = 500 ;100        

    PreparationTime        = 1  

    PersistentPrepTime    = 0

    PackTime        = 2000

    AwardXPForTriggering    = 0

    MustFinishAbility    = Yes

    WhichSpecialPower     = 3

    ; BusyForDuration    = 1000

    ; StopUnitBeforeActivating = Yes

End

15. Next, set up three behaviors in the object that look something like this:

Code

Behavior = ModelConditionUpgrade ModuleTag_MountModelCondition

     TriggeredBy        = Upgrade_HelmDefenderMount

     AddConditionFlags  = MOUNTED

End



Behavior = ObjectCreationUpgrade ModuleTag_RemoveUpgrades1

     TriggeredBy   = Upgrade_HelmDefenderDisMount    

     RemoveUpgrade = Upgrade_HelmDefenderMount

End



Behavior = ObjectCreationUpgrade ModuleTag_RemoveUpgrades2

     TriggeredBy   = Upgrade_HelmDefenderMount

     RemoveUpgrade = Upgrade_HelmDefenderDisMount

End

16. Now set up three more behaviors triggering the locomotor, armor, and weapon upgrade.

Code

Behavior = LocomotorSetUpgrade ModuleTag_LocomotorMount

     TriggeredBy = Upgrade_HelmDefenderMount

End



Behavior = WeaponSetUpgrade MountWeapon

     TriggeredBy               = Upgrade_HelmDefenderMount

     WeaponCondition           = PLAYER_UPGRADE

End



Behavior = ArmorUpgrade ModuleTag_MountArmor

     TriggeredBy          = Upgrade_HelmDefenderMount

     ArmorSetFlag          = PLAYER_UPGRADE

End

17. Finally, create two CommandSetUpgrade behaviors.

Code

Behavior = CommandSetUpgrade ModuleTag_CommandSetSwitch

     TriggeredBy        = Upgrade_HelmDefenderMount

     ConflictsWith        = Upgrade_HelmDefenderDisMount

     CommandSet        = HelmDefenderDismountCommandSet

End



Behavior = CommandSetUpgrade ModuleTag_CommandSetSwitch2

     TriggeredBy    = Upgrade_HelmDefenderDisMount

     ConflictsWith    = Upgrade_HelmDefenderMount

     CommandSet    = HelmDefenderCommandSet

End

So what in the world did we just do?! Well, when the player presses the mount commandbutton, it activates the special power modules. The actual special power does nothing. By using the script events, it recognizes when SPECIAL_POWER_THREE is activated and it triggers a function that grants the upgrade Upgrade_HelmDefenderMount. That upgrade triggers all the PLAYER_UPGRADE behaviors to activate and adds the condition flag MOUNT to your object. Now, when the player presses the dismount button, it removes the SPECIAL_POWER_THREE condition and that triggers a function that removes the upgrade Upgrade_HelmDefenderMount and grants the upgrade Upgrade_HelmDefenderDisMount That removes all the PLAYER_UPGRADE the object has and switches the commandset back to the original one.

18. Now that it works for the human player, how about the AI? You need these three behaviors in your unit object:

Code

Behavior = SpecialEnemySenseUpdate ModuleTag_DefenderSeesPikemen

        SpecialEnemyFilter = NONE +IsengardPikemanHorde +IsengardPikemanHordePorcupine

        ScanRange = 500

        ScanInterval = 2000

End



Behavior = DoCommandUpgrade Module_DoCommandMount    

        TriggeredBy = Upgrade_ObjectLevel1 Upgrade_ObjectUnderAIControl Upgrade_MountAI

        RequiresAllTriggers = Yes

        GetUpgradeCommandButtonName = Command_HelmDefenderMount

End



Behavior = DoCommandUpgrade Module_DoCommandDismount

        TriggeredBy = Upgrade_ObjectUnderAIControl Upgrade_DisMountAI

        RequiresAllTriggers = Yes

        GetUpgradeCommandButtonName = Command_HelmDefenderDisMount

End

To understand how it all works for the AI, please read SÃ»lherokhh's AI tutorial provided in the references below. He does an excellent job explaining how it all works.

Ugh... ok, Sul, I tried your method and I was able to improve everything except for one thing. The animation will play when it's just an individual unit, but when it's a horde, it refuses to play one. I have tried tons of things but nothing works. I'll update this tutorial after I try some other things out.

EDIT: Yeah, I'm stumped. Unless someone can find a way to get the animation to work for the horde, it looks like we'll have to do without them :( Once I clean up and double check to make sure everything runs correctly, I'll edit and fix up the tutorial.

Re-did the tutorial. If you find a solution to any of the problems on Page 7, please let me know :)

Sweet! :) It sure looks perfectly functional, and since you tested it, we now all know it works!! :D

For further ideas on switching commandsets (which are identical, except for the single button that buys upgrades) and the use of specific animations to play for mounting /dismounting (by using a special power instead of an OBJECT_UPGRADE button), refer to 'blackrider_SEE.ini' from S.E.E. The specialpower (and LocomotorUpgrades) would have to be installed in both horde AND hordemember, but the LuaFunctions would only be needed in the horde, just like the CommandSetMonitor) These black riders don't mount horses the usual way, as the normal mount behavior has been reserved for mounting fellbeasts.

Yeah, the commandset is quite an annoyance but I can't find any other solution to the problem :(

JEV3 - Friday December 21, 2007 - 11:50

Pity the commandset is so unfriendly... But to have a horde be able to mount and dismount is worth it.

Please leave comments :)

EDIT: Fixed an error in article... HorseHordeContain is the behavior you want to use for the horde behavior
