Fly Trap Spell; need help

[bananaHUNT]

I've got this idea for a spell: An AoE targetable spell that sets up a 'fly trap'. Enemy units that enter the AoE, cannot go out for the duration of the spell (but they can walk around in it normally). Allied units can walk through it like it is not even there.

But.. I have no idea how to do this; can anyone help? I know a bit of GUI, but dont understand JASS.

 

[Charapanga]

What you do is, pick every enemy(boolean comparisson) unit within X(all units within range matching condition) of Targeted Point then create a dummy that casts a modified entangling roots on them(picked unit)...

 

[Beetlebomb]

Do you want it to lay the trap and then go off later of lay the trap and go off immediately?(or both)


Having it go off immediately can be easy, but having it go off later is challenging. I can't think of a way to do it in GUI that would make it MUI...wait...yes i can(BRAINSTORM!).

Make invisible dummies and run a timer expiration event that checks every so often on if there's a flying unit present and then do whatever you will to happen.

If you need help with doing that, let me know.

Give it a try first ^^

Thanks for your replies but entangling roots wont work, because the units can move freely within the trap, just not outside the aoe. Here is a picture:

How could i make like pathing blockers only for enemy units?

 

[Genkora]

I have no idea how you could do it the way you want. You could make a dummy unit cast a bunch of invisible invulnerable wards around a point using polar offsets, but that would restrict allied units as well. Using the same polar offset idea, you could maybe move any enemy unit that goes so far from the middle point backwards a little bit. Like, it tries to leave, and then a trigger moves it instantly back inside. hang on, let me try and make something that might work.

 

[Romek]

You could try making 360 rects around the circle, then adding them all to a region.
If an ally enters the region, disable pathing.
If an ally leaves it, enable pathing.
If an enemy enters, do nothing.

You'd need to make the pathing blockers this way too.

 

[Genkora]

Sorry, it seems a bit out of my league on this one. I couldn't fit the right pieces together.

 

[Azlier]

I suggest a script that, with a timer, sets the affected units to units within range of the ward. And then it checks if the affected group is further away from the ward than they should be. If so, pull them back a distance of about ten towards the ward. It certainly seems plausible... I've done the very opposite, the pushing away of units from a point. Mine has some extra functions to check if the unit is undead or not, and the enemy only thing is done within Targets Allowed. Here's a demo map. No terrain or anything, only a paladin, a random race's starting units, and some testing undead. Sanctuary Aura is cloned from Devotion Aura . Say nothing about the name, its a work in progress. Note: requires NewGen.

I have now set up the trap, but it's fully closed atm. Now I need something to let allies enter and leave without problems, and let enemies enter, but not leave for the duration of the trap.

 

[bananaHUNT]

Ok, I changed the whole thing. First I set up doodads in a circle and tried to make it pathable - but that didn't work too well. Now I have something more easier, like azlier suggested. I still have a problem though, here are my triggers:

the first one is where the trap is set up (enlarged Ensnare model)

FT1
    Events
        Unit - A unit Starts the effect of an ability
    Conditions
        (Ability being cast) Equal to Fly Trap 
    Actions
        Set ItCaster[CV] = (Casting unit)
        Set ItTargetPt[CV] = (Target point of ability being cast)
        Unit - Create 1 FlyTrap (2) for (Owner of ItCaster[CV]) at ItTargetPt[CV] facing ItTargetPt[CV]
        Set ItTrap[CV] = (Last created unit)
        Unit - Add a (5.00 x (Real((Level of Fly Trap  for ItCaster[CV])))) second Generic expiration timer to ItTrap[CV]

here it checks if a unit is at the border of the trap and then sends it back in.

FT2
    Events
        Time - Every 0.01 seconds of game time
    Conditions
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                ((Playable map area) contains ItTrap[CV]) Equal to True
            Then - Actions
                Unit Group - Pick every unit in (Units within 300.00 of (Position of ItTrap[CV])) and do (Actions)
                    Loop - Actions
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)

                                ((Picked unit) is in (Units within 250.00 of (Position of ItTrap[CV]))) Equal to False
                            Then - Actions
                                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                                    If - Conditions
                                        ((Picked unit) belongs to an enemy of (Owner of ItCaster[CV])) Equal to True
                                        ((Picked unit) has buff Fly Trap (Trapped)) Equal to True
                                    Then - Actions

                                            If - Conditions
                                                ((Picked unit) belongs to an enemy of (Owner of ItCaster[CV])) Equal to True
                                                ((Picked unit) has buff Fly Trap (Trapped)) Equal to False
                                            Then - Actions
                                                Unit - Order (Picked unit) to Move To (Position of ItTrap[CV])
                                                Unit - Create 1 Dummy for (Owner of ItCaster[CV]) at (Position of (Picked unit)) facing Default building facing degrees
                                                Unit - Add a 5.00 second Generic expiration timer to (Last created unit)
                                                Unit - Set level of Fly Trapped  for (Last created unit) to (Level of Fly Trap  for ItCaster[CV])
                                                Unit - Order (Last created unit) to Orc Shaman - Purge (Picked unit)
                                            Else - Actions
                            Else - Actions
            Else - Actions

to remove the buff given by the trap; when the time is over:

FT3
    Events
        Unit - A unit Dies
    Conditions
        (Unit-type of (Dying unit)) Equal to FlyTrap (2)
    Actions
        Unit - Remove (Dying unit) from the game
        Unit Group - Pick every unit in (Units within 300.00 of (Position of (Dying unit))) and do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        ((Picked unit) has buff Fly Trap (Trapped)) Equal to True
                    Then - Actions
                        Unit - Remove Fly Trap (Trapped) buff from (Picked unit)
                    Else - Actions

Now my problem is that when i cast another trap, the units respond normally to the second trap, but can walk through the first one as if it isn't even there.

My second problem is that I do not know if simply ordering the units between 300-250 AoE of the trap's center to move inwards. It works in my test map on neutral creeps, but will this stop player-controlled hero's from going out when they like.. click alot?
thanks for your help!

Then - Actions
Unit Group - Pick every unit in (Units within 300.00 of (Position of ItTrap[CV]))

Leakie. Set UnitGroup1 = (Units in (Units within 300.00 of ItTargetPt[CV]). You have already set the position of the trap (through the ability being cast), so Unit Group - Pick up every unit in UnitGroup1 and do Actions. Remove it when your triggers ends, using Custom Script: call DestroyGroup (udg_UnitGroup1)

If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
((Picked unit) is in (Units within 250.00 of (Position of ItTrap[CV]))) Equal to False
Then - Actions

You pick up every unit in units 300.00 range away and you add this condition? Why? Remove it. Go on with the other conditions you added (((Picked unit) belongs to an enemy of (Owner of ItCaster[CV])) Equal to True
((Picked unit) has buff Fly Trap (Trapped)) Equal to False)

Unit - Order (Picked unit) to Move To (Position of ItTrap[CV])

Leakie! Damn, since your trap is created at the ability being cast point, just use it, since you added it in a variable: Unit - Order (Picked unit) to Move To (ItTargetPt[CV])

Unit - Create 1 Dummy for (Owner of ItCaster[CV]) at (Position of (Picked unit))

Leakie... When you pick up every unit from the UnitGroup1, set Point1 = (Position of (Picked unit))
AND now do your above action: Unit - Create 1 Dummy for (Owner of ItCaster[CV]) at (Point1); remove it: Custom script: call RemoveLocation (udg_Point1)

You aldo did not remove the point "ItTargetPt[CV]", do it: Custom script: call RemoveLocation (udg_ItTargetPt[CV])

Unit Group - Pick every unit in (Units within 300.00 of (Position of (Dying unit)))

2 leaks already. Set Point2 = (Position of (Dying unit)) (remove it: Custom script: call RemoveLocation (udg_Point2)) and Set UnitGroup2 = Units within 300.00 of Point2 (remove it: cal DestroyGroup (udg_UnitGroup2))

Done for leaks. The fact that it doesn't proc normally on your second try is maybe because it requires a Countdown timer instead of an expiration timer. Since your actual effect is based on the Trap Dummy, just start a countdown timer, setting it in a variable and remove it: Custom script: call DestroyTimer (udg_<yourtimername>). Then in the trigger "a unit dies", add "<yourtimername> expires" instead and make all those actions, plus "Unit - Kill (ItTrap[CV])"

 

[bananaHUNT]

Wow huge thanks man; I'm not so good with leaks hehe The reason I pick every unit within 250 = false, is because i want them to be moved to the inside when they try to escape, not all the time
edit; have to spread some rep first before i can +rep you
edit2; it gives 1 error now tough: "expected a name" on call RemoveLocation (udg_ItTargetPt[CV]) ?

Make your second trigger not initially enabled and turn on the second trigger through your first trigger.

 

[bananaHUNT]

Yeah i did that already, and it reduced the lag, but it still doesn't work when you have 2 traps set up.. I'll attach my map if you wanna take a look at it

 

[Pharaoh_]

After a year, i finally made it: View attachment FlyTrap.w3x

 

[mordocai]

how come they get netted down? i thought the point was for them to actualy be able to move around inside it

 

[bananaHUNT]

how come they get netted down? i thought the point was for them to actualy be able to move around inside it

Well.. yeah Thanks for the effort and time you put in this Pharaoh but that's not really what i mean. Once enemies are in the trap, the cannot get out, but they can walk freely within the trap. Enemies should be able to walk through it as if it isn't there.

mby this is what you mean, strongly think so^^
