Treewalking?

[Spellbound]

Is it possible to make a unit ignore collision with trees but respect unit/building and cliff collision?

 

[Chaosy]

You can do something like checking if there is a tree within 50 range of the unit's facing. Then disable collision completely.

 

[teozamait]

It could be exploited and you would have to be very careful with placement of trees, if a cliff is near a tree for example you could have that unit get stuck on the cliff.

I think this would work. I just translated Chaosy's solution into this so credits goes for him.

• Loop
  • Events
    • Time - Every 0.05 seconds of game time
  • Conditions
  • Actions
    • Set TempUnit = Knight 0001 <gen>
    • Set TempPoint = ((Position of TempUnit) offset by 50.00 towards (Facing of TempUnit) degrees)
    • Destructible - Pick every destructible within (Radius-Value) of TempPoint and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • IsNearToTrees Equal to False
            • (Destructible-type of (Picked destructible)) Equal to Summer Tree Wall
            • ((Picked destructible) is alive) Equal to True
          • Then - Actions
            • Set IsNearToTrees = True
          • Else - Actions
    • Custom script: call RemoveLocation(udg_TempPoint)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • IsNearToTrees Equal to True
      • Then - Actions
        • Unit - Turn collision for TempUnit Off
      • Else - Actions
        • Unit - Turn collision for TempUnit On
    • Set IsNearToTrees = False

Also, be careful as this can bugged out the unit's collision like being stuck on a cliff.

Hmm, interesting. I mean it could work. Right now I'm just opting to disable the collision for a second or so. See the unit only had to be treewalking for a small period as it's created at the location of a dying tree. Unfortunately, dying trees retain their pathing a bit too long for my needs, so a simple kill tree --> create unit --> disable collision --> order move --> wait 1 second --> enable collision will have to do until something more like Ghost (visible) but for Destructibles comes along, if it ever does.

 

[Rainmaker]

Does the tree pathing by any chance disappear sooner if you use Destructible - Remove, rather than Destructible - Kill?

 

[Spellbound]

I imagine it would, but I need the death animation or else it would looks weird. The one thing I can think of doing is to use Force of Nature, but that would require one dummy unit creating another unit which to me just looks like unnecessary overhead.

 

[SAUS]

You can use the native functions SetUnitX(u, x) and SetUnitY(u, y). These functions move the unit naively - that is to say it will put them in impassable terrain if you tell it to.

You would have to use custom script to use these, but it would look something like:

• trigger
• events
• conditions
• actions
  • set myUnit = Last created unit
  • Custom script: call SetUnitX(udg_myUnit, GetLocationX(udg_myPoint))
  • Custom script: call SetUnitY(udg_myUnit, GetLocationY(udg_myPoint))

This code needs you to have a unit variable called myUnit (can be changed, just you need to update the custom script to match) and point variable called myPoint (also can be changed). myUnit should be the unit you just spawned and myPoint should be the point that you want to spawn the unit at. Just add these lines after you create the unit.

 

[Spellbound]

The unit is using it's own movement to move so moving it by triggers won't help. As the treant is created, I move it to the tree's location, but then it's immediately ordered to move which means that if the tree is still there, the treant will be displaced outside of the tree's pathing immediately. On the flip side, if I disable the unit's collision, it can stay within the tree's pathing while it moves.

With that said, what if I just disable the tree's collision? Is that possible?

It will be possible but most units will have an access through those trees.

 

[Spellbound]

Not really an issue since the tree is dying anyway.

Sorry, didn't payed attention through the replies.

 

[Spellbound]

So... how do I remove the collision of a specific destructible then?

 

[Skyflash]

you can add this condition to prevent Cliff stuck bug

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Terrain pathing at (Your_Point) of type Walkability is off) Equal to True
  • Then - Actions
  • Else - Actions
