Restrict unit's movement radius

[Blazing_Legion]

Is it possible to stop a unit from moving after it has traveled a certain distance from a point without ordering it to stop or moving it backward.

 

[Lender]

well u can set the units movement speed to 0. i think that should work

 

[Maker]

• Custom script: call SetUnitPropWindow(*unit*, 0)

 

[Blazing_Legion]

No it doesn't work because for some reason changing a units movespeeed to 0 still allows it to move

 

[Lender]

u have to set default minimum movement speed in "gameplay constants" cus 0 means the default value which is 150 by default

 

[Blazing_Legion]

K but even if the units movement speed is 0 it won't allow to move within the givin range because it won't be able to get back into it. And what does unit prop window do?

 

[HuanAk]

try play around with some of game constant.

I think there are one call "guard distance" or similar, but those setting are very buggy, I heard it only work for creep and may not work for player's unit.

for example, the neutral creep in Dota will walk back to spawn point if they move too far.

 

[Spartipilo]

Custom script: call SetUnitPropWindow(*unit*, 0) is the best way. If you set Movement Speed to 0, it will never allow your unit to go under you "Minimum Speed" you can change in the Gamplay Constants, however, UnitPropWindow = 0 works for what you want, and goes over the minimum movement speed, since it doesn't mess with Movement Speed, but with something else, I don't know what But prevents moving

 

[Blazing_Legion]

Still as i said before this will cause the unit to completely be unable to move i just want it to be as if the unit was blocked from going any further like with paving blockers but i can't use them as they will block other units as well.

 

[Lender]

So u would like to do a barrier spell or something? Or just to cause the creeps not to move too far away from camp positions?
If u want the first one then the best way is pulling back the unit(i can help if u want) and i think this is it, don't know how could that be possible in other ways. (if u would like it to effect only the enemy units)

 

[Blazing_Legion]

Ok ill tell you what its actually for. I have created towers that are meant to have a specific movement range but i just need them to be able to move them no further than their range from their original point without affecting the creeps.

Here's the basic idea:

Trigger

• System
  • Events
    • Time - Every 0.03 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in grp and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Distance between (Position of (Picked unit)) and (Center of (Playable map area))) Greater than or equal to 500.00
          • Then - Actions
            • Unit - Move (Picked unit) instantly to ((Center of (Playable map area)) offset by 500.00 towards (Angle from (Center of (Playable map area)) to (Position of (Picked unit))) degrees)
          • Else - Actions

Add units into the group. If the group is empty, turn the trigger off.

As each unit can have a different center point, you could store it into a hashtable and then load it in this trigger. Alternatively, use a unit indexer by Bribe (got to spells database for that) and a point array.

Ok i have made my trigger and it works but doesn't look that good that's why i would have prefered something that simply blocks it from going further. Well since no one seems to be able to give me a gui solution is this possible using jass if a jass solution is given please explain to me how to use it and i would give +rep if i knew how.

 

[kleinerhauck]

you could move the unit only a few units every 0.03 seconds.. thats how those slide effects usually work.
(Add the unit to a unit group, and loop through the group every 0.03sec, checking whether they are outside the boundaries)
Make sure to remove leaks then!

Use SetUnitX/Y, which you do not find in GUI. These do not interrupt orders and such. Therefore it will look like your unit keeps running against an invisible wall.

Considering Maker's trigger as starting position, save the radius in a variable "radius" and your center location in a variable "center". Then replace your current Move action with two "Custom Script" lines (3rd action from above in the all actions list) and put this in:

call SetUnitX(GetEnumUnit(), GetLocationX(udg_center) + udg_radius * Cos(Atan2(GetUnitY(GetEnumUnit()) - GetLocationY(udg_center), GetUnitX(GetEnumUnit()) - GetLocationX(udg_center))))
call SetUnitY(GetEnumUnit(), GetLocationY(udg_center) + udg_radius * Sin(Atan2(GetUnitY(GetEnumUnit()) - GetLocationY(udg_center), GetUnitX(GetEnumUnit()) - GetLocationX(udg_center))))

Okay I have created a system for you

The settings are in the SPMS Setup trigger

You need to use the Unit - A unit enters (Playable map area) to register your unit into the trigger

You're talking about towers, right ?

I assumed it must be built by your workers or something, therefore when the tower first enters the map (not built yet, but when the worker initially starts to build its base of the structure), the 'towers' or we refer it as unit in the trigger, will be automatically be registered, therefore the system is going on

Have fun!

 

[Blazing_Legion]

Ok thanks guys first ill try the set unit xy one. And actually my towers become units at the start of each wave

 

[defskull]

Errr you can at least try check my test map... -,-

 

[crehym]

Nice map. @BlazingLegion, defskull provided you with an example and perhaps the best solution to your problem.

 

[Garfield1337]

Setting propulsion window to 0 is much more easier, efficient and better looking (since the unit doesn't even play the walking animation).
It's shown in third post, by Maker.

 

[Blazing_Legion]

Sorry I've got exams at the moment but of course ill test your test map i am after all trying to find the best solution to this problem.

 

[defskull]

It's only 1 minute test of that map, that's all.

 

[Blazing_Legion]

Thanks defskull i have tried to include your system in my map however it does not stop the units from moving to far and dont know why i will upload what ive got so far so please if you can find whats wrong tell me the units are added to the group in the start spawn units trigger and you are all welcome to play the first wave if you wish. Also tell me what you think thanks guys for all your help.

 

[defskull]

It is because, in your map, each unit has different settings of Area of Effect indicator, therefore, you need to set for each of the unit in a trigger

Like for example, Bandit Lord has different AoE compared to Bandit, therefore a setup for each unit is required

As you can see from my original test map, did you notice the DistanceMax variable ?

That is your restriction radius for a unit

In that test map, I only make it for only 1 unit, therefore it does not suit your map since you want it to vary for each unit (you never mention this in the first post, therefore your information is misleading)

Next time, please be specific...

Don't just keep adding conditions in every post, it will make us helpers, tired.

EDIT:
Or you can reset your original location instead of restricting movement ?

 

[Blazing_Legion]

So i have set each units move radius as their custom value why doesn't this work.
