Help with a slowing trail spell

[b_ray210]

Hey guys its been a while since i edited and ive forgotten everything. Im trying to make a spell that i can cast and for the next (10?) seconds it lays a trail behind him that slows units that walk in it. ive figured out how to lay the trail (im using little webs every 0.35 seconds) but they stack up on top of eachother if i stop moving and it looks bad. also i cant figure out how to make it slow units that walk on it. thanks guys! (and girls)

oh yea its an instant spell that effects the caster

Set the point where a web is created to a point variable like LastPointOfWeb or something. If the point of the hero is less than X range away from LastPointOfWeb, skip the web creation.

Add Tornado Slow Aura to the webs; they are units, right?

k this is a similar spell ive created but the "dummy unit highland archer blur" still stacks up if the hero stops moving

I call [ljass]SetUnitMoveSpeed()[/ljass].

• Unit - Set (Triggering unit) movement speed to 300.00

call SetUnitMoveSpeed(GetTriggerUnit(),300.)

You'd have to detect a "Unit within range" for the dummy unit... probably easier in JASS, since you could make a [ljass]local trigger[/ljass] variable.

k i dont really understand what youre doing with movespeed haha i understand the movespeed thing now ill just use the tornado slow aura and put the range very low. the thing im having trouble with is how the dummy units (webs that make up the trail) or the "dummy highland archer blur" in the example i posted above, stack up if the triggering unit stops moving

 

[Ashlebede]

Shouldn't, if your dummy unit has no pathing/locust.

Oh, and there are leaks in that.

And that action will change a unit's movespeed permanently... you'd have to register an event in yet another trigger for when "A unit comes within X of UNIT". That way you can detect when a unit comes close enough and change its movespeed, starting a timer to set it back to how it was before... meh, GUI is too complicated. u_u

 

[b_ray210]

My dummy does have locust and no pathing

What are the leaks? im really bad with stuff like that haha

and if i add the slow aura to the webs then the unit that runs onto it wont be permanentely slowed will it? if i put the duration to like 0.2 seconds or something

 

[Ashlebede]

Leaks : http://www.thehelper.net/forums/showthread.php?t=27219

Correct me if I'm wrong, anyone, but I'm pretty sure an aura should slow all units within the range, renewing every (duration) seconds.

 

[b_ray210]

k my internet is bugging so i dont know if ive already posted this reply.

1) my dummys have no pathing and they have locust but they still stack. is there something wrong with my trigger?

2) what are the leaks im really bad with them

3) if i add a slow aura to the "trail" and a unit runs on it wouldnt it just have the aura as long as the duration says, not permanentely?

 

[Ashlebede]

1) I don't see anything wrong there, except for the leaks. u_u

2) Read the tutorial about leaks? Link in previous post.

Leaks are "leftovers" after a trigger's execution. For instance, every time you use (Position of (Triggering unit)), a new point is created and cannot be retrieved. So the point remains there and takes a few bytes of RAM.

After a couple hundreds or thousands of leaks, there will be much more lag on your map, since you need more RAM to run the program. At some point, the map might become unplayable. Groups, regions and special effects may also leak, as well as a few more things.

3) If you played a melee game and had a unit with Trueshot aura, would its effect last even after the unit is outside the aura's range? No, that would be imbalanced. It removes the aura's effect when a unit is not in range of the aura anymore.

 

[b_ray210]

1) alright yea thats the main problem with it so that sucks

2) yea sorry my internet was not refreshing right so i didnt know if i had posted already haha

3) i know thats what im saying though. its not permanent you said it would be and i dont want it to be so were saying the same thing basically haha

+ rep anyways

Units with Locust aren't picked up by "Pick all units". Replace that part with a distance check between where you are now and where you were before.

Do an IF/THEN/ELSE. IF (Distance between LastWebPoint) and (TempPoint) is greater than 100, THEN (Create 1 Web thing) and Set LastWebPoint equal to (Position of (Dude)), ELSE Do nothing

 

[b_ray210]

oh thanks tha will work much better. the only problem is if the caster turns around and walks back over the dummys but that will likely not happen in the game im making.
thanks!

 

[Cheddar]

Oh, I kinda forgot that could happen. Well, as long as they aren't stacking as they were before, I guess...
