How would you do this though? I don't think you can just sub in a tile for a model.

No I would use an unit ability to add a prop to a tile, like how fortify adds a bunch of wooden spikes to a tile. This way I can create the tower using the tile editor. Your right it would be much better to just have a unit model that looks like a tower but that's probably beyond me.

Yeah it's definitely an idea worth pursuing. 

You couldn't sub in a tile, but you could sub in a prop.... have a look for K_Wall_Tower_Advanced_01.hkb.  It might work by just changing the model type for the unit to a prop like that.

The other thing you could probably do is make the model transparent and/or really small (just scale it down to 0.1 or whatever) then do the autocast fortifytower thing and you probably wouldn't see the tiny model under the tower prop.

I think you could fix most of these things.  A lot of abilities you can make a unit immune to by giving them a unitstat and modding the ability so it doesn't work if the target has a unitstat.

Thanks Halmal242 and abob101, that's some good advice.

Both directly using a prop as a model and using an ability to create a tile have advantages. Directly using the model means the tower would disappear on death, while creating a tile would allow me to combine props and make it look much better. Creating a tile also would allow my tower to shoot multiple arrows and function as a group of units instead of just one, but again would leave the tower tile after the unit dies. I'm not sure which way I want to go.

I guess you could always go with your original idea... but have the unit at ground level.  Just give them a brick wall type thing around them.  Wouldn't really have the tower type feel more of a heavy fortification.

How would you go about doing that? I didn't think you could trigger something upon the death of a unit.

For that to work doesn't the spell have to do the killing? I have never got it to work any other way.

Not sure if this is the case if the spell is placed normally but when created through autocast Worldprops seem to always be permanent. The Duration and DurationOnTile appear to do nothing.

What would trigger the damage the spell does? I don't this is possible either. Darn it doesn't seem like it's possible to remove the tile upon the death of the caster.

I guess you could still use a prop as a unitmodel and have it shoot a single arrow, but that's not nearly as cool as having a better looking tower that leaves ruins upon it's destruction.

Unfortunately adding <ApplytoCaster> doesn't work on ReflectDamage, so I couldn't get that to work either. Ya you could do a lot with spells that trigger on death. Like units that explode, leave remains, change form, or you know help modders make guardtowers... I find it weird we can't even change the Y-Position of units, that's usually pretty basic. With that I could make really cool looking tower tiles that any unit could hang out in and fire out of, thus destroying them wouldn't be necessary.

Ah.... yeah there's a thought pm, didn't think of that....

(goes off to try something)

Give it to a unit.... should lift them horse height of the ground.  Change the item <Scale> to make them higher.

Fairly sure that's exactly what you want.

Edit -> With that example, the guys feet will slide around slightly now and then.  To improve it I think you'd want to replace the "MountedHorseAnimationPack" above with a custom one and remove the horse animation that causes the problem.  Should be fixable though.

This could be cool if it works.

Another Edit -> Just did some more testing, could be a few things to iron out but I think it works.  *Might* need to add a modelfile back in.. I think there might be some weird things happening without one... needs more testing.

That is nice. Are you setting up the watch tower to be immune to melee damage?

Ahh that's coming along nicely, cool tower.  It looks neat  

Try this:

<GameModifier>
  <ModType>Map</ModType>
  <Attribute>PlaceTerrain</Attribute>
  <TerrainType>CaveWall</TerrainType>
</GameModifier>

Fairly sure that should work.  At work can't test at the minute.
