Create a system

[Kusanagi Kuro]

I want to create a system which will stored all informations about a unit every seconds in the last 5 seconds. I mean it will store the HP, mana, position of the unit up to 5 seconds ago. If u still cannot understand what I really want, u should have a look through Dota Nerubian Weaver's Ultimate Time Warp. That ability allows Weaver to travel back to the position he was in 5 seconds ago, with his hp and mana like what he had 5 seconds ago.
I'm really sorry if many people cant understand my problem because of my terrible explanation but I have tried my best. If someone can explain it clearer, I'll glad if he/she post it.

Every X time (something between 0.1 and 0.5 seconds seems the best imo), you save things in variables/hashtables. Let's say we make it 6seconds as you said, with a 0.5 periodic, you'll have 6/0,5 (12). So, you use only 12arrays/hashtable emplacments/variables. Every 0.5 seconds, for the values stored from 11 to 1, you save values to the next array/hashtable emplacment/variable (actual one + 1), and you save the actual ones at the array 1.
When your unit casts the spell, you give it the values saved in 12.

Also, for the unit's location, better to use coordonnates to avoid leaks.

[Link to TheHelper.net thread]

okay, im actually not a dota player too, but i think i know how it works.
It safes every value (life, mana, gold, etc) in a variable with arrays every 0.01/2/3/4/5 seconds and if casting you get the older array and set the values (life, mana, gold, etc) to the value you ahve saved.

Here's a couple of solutions.

 

[edo494]

if you want it MPI, make each variable array of size 12(or 15 for neutrals) (like for health, mana, positionX, positionY[X and Y to prevent leaks] and other stuff) and create periodic timer for like 0.1 sec(to not lag the game too much) and pick the unit of type whoever and store those values

if you want it MUI, just use some indexer and do the same as above(the size of array is undefined in that case, so you can keep it in 1 in gui)

 

[13oot-Me]

Every 5 seconds of game time you would store all the units information (hp, mana, position, attributes or whatever else you wanted) into a variable array. The array value would then be that units index number, stores as the key.

 

[MasterTrainer]

How I look at it, you need a unit indexer, and a periodic trigger that runs every 5 seconds, and will store real hp, real mana, real x,y, and integer stats in different respective variables.

 

[edo494]

oh yea saving it every 0.1 is not good, but nor is 5 seconds, because If I cast spell at 3rd second, I will only get moved back to 3 seconds back not 5

there is a bit more complexity to that after all

 

[Vinz]

Every 1 second should do. And use a hash.

 

[edo494]

yea, you could just make 5 different values, and push them from top to down(move them, so you have like 1->0, 2->1, 3->2, 4->3, new->4 and when you cast the spell, load the 0th and flush the rest

 

[deathismyfriend]

Since u would be moving all units back u should use unit indexer by bribe. Every .1 seconds would be best. Then u use arrays and store all the into u need.

Pretty much wat edo said.

U will need a couple of arrays to store the different times. This will be a great system I made in vJass. GUI with the arrays will be a lot.

 

[MasterTrainer]

Hmm... I thought systems could only be made MPI and not MUI... woah.

 

[Kusanagi Kuro]

I'm thinking of using both unit indexer and hashtable. When I finished, I 'll post the trigger. Tell me what u think after that.

 

[MasterTrainer]

I just found how to incorporate this system in my map; if I may, can I use it? (Credits go to 'ya of course :3)

 

[Adiktuz]

This is better put in hashtables rather than arrays considering the quantity of items that can possibly be saved...

Hmm... I thought systems could only be made MPI and not MUI... woah.

Of course they can be MUI... Where did you even get that idea?

For example: A missile system can be and needs to be MUI...

 

[MasterTrainer]

@Adiktuz umm.... well I always thought that systems can be used by different units at the same time because well... it's a system so it does not need to be ca- wait I understand now; lol. Lol indeed.

 

[Kusanagi Kuro]

Here is my current time system. It's pretty simple so if anyone thinks there will be problems with it, plz tell me so I can fix it.

System

• Time Work
  • Events
    • Time - Every 1.00 seconds of game time
  • Conditions
  • Actions
    • Set tempGroup = (Units in (Playable map area) matching ((((Matching unit) is A Hero) Equal to True) and (((Owner of (Matching unit)) controller) Equal to User)))
    • Unit Group - Pick every unit in tempGroup and do (Actions)
      • Loop - Actions
        • Set CV = (Custom value of (Picked unit))
        • Set TimePosition[CV] = (Position of (Picked unit))
        • Set TimeHP[CV] = (Life of (Picked unit))
        • Set TimeMana[CV] = (Mana of (Picked unit))
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • TimeInteger[CV] Equal to 5
          • Then - Actions
            • Set TimeInteger[CV] = 1
          • Else - Actions
            • Set TimeInteger[CV] = (TimeInteger[CV] + 1)
        • Hashtable - Save TimeHP[CV] as TimeInteger[CV] of (Key (Picked unit)) in TimeHashtable
        • Hashtable - Save TimeMana[CV] as (TimeInteger[CV] x 10) of (Key (Picked unit)) in TimeHashtable
        • Hashtable - Save Handle OfTimePosition[CV] as (TimeInteger[CV] x 100) of (Key (Picked unit)) in TimeHashtable
        • Custom script: call RemoveLocation(udg_TimePosition[udg_CV])

Some explanation about how this will work: For example, I want to get my unit back 3s ago, then I'll check the TimeInteger, if it is less than 3, then set tempInt = 5 - TimeInteger, else set tempInt = TimeInteger - 3. Then based on the thing I want to get (HP = tempInt, Mana = tempInt x 10 and Position = tempInt x 100). Pretty simple, I think.
Some little question about the memory leaks:
Does Units in (playable area) leaks? The same question with (All Players)?

 

[edo494]

Unit group always leaks if not cleared
you should put one more custom script at the end(outside the group enumeration) so you destroy it

of you mean All Players as force(player group) then no that will not leak and you should mever destroy that one

 

[MasterTrainer]

If I learned anything that deathismyfriend has showed me many times, I should tell you that it will be better if you stored (Picked Unit) and (Matching Unit) in a var and yes, (Units in (Playable Map Area)) does leak; leaks a loc.

 

[Kusanagi Kuro]

Well, guess I'll have to put it in . Oh, and MasterTrainer, if u dont think this system is too basic, too inefficency, then it's my pleasure to give it to ur map .

 

[deathismyfriend]

I might make this in vJass later so u can get a great time period. Ill see what I can do for ya when I get home later

 

[Vinz]

Playable Map Area is not a loc; it is a rect.

 

[Wrda]

Playable Map Area is not a loc; it is a rect.

yep.
@hayaku1412, don't use every 1 seconds... its innacurate, use 0.1 or 0.05, this would be the best.

 

[deathismyfriend]

yep.
@hayaku1412, don't use every 1 seconds... its innacurate, use 0.1 or 0.05, this would be the best.

the problem is that with a system like this .05 would allow it to track about 409 units. That should be ideal if u dont allow this to store structures. if u do that number will easily be reached

 

[Wrda]

the problem is that with a system like this .05 would allow it to track about 409 units.

??? track about 409 units? What are you talking about?

 

[deathismyfriend]

Ooo it's only for heroes nvm lol

@ hayaku1412
if u want this system to go back in time how do u want it to work ? do u want units to go back in time in a specific area ? do u want every unit on the map to go back in time ?

 

[Kusanagi Kuro]

Well, I can do all of that. .
The reason why I only track the hero is that my map is a boss fight map, no creeps .

 

[deathismyfriend]

ooo ok lol. I might do something like this in vJass for more efficiency and a lot more speed. if i do ill tell u so u can see if u want to use it to. Also watch using .02
that only allows this to track about 163 units b4 it will break the triggers. u also dont keep track of the units lvl ?

 

[Kusanagi Kuro]

Yes. Dont want to touch the exp of that unit. . Travel back to time doesnt mean u get older or younger. It's just urself in the different time line. .
My purpose creating this system is my spell. It reverse the time in the targeted area back 5s.

 

[deathismyfriend]

ok lol

 

[MasterTrainer]

Rect... oh it seems I misunderstood the use of rects and locs; thanks for the correction.

 

[deathismyfriend]

a rect is the region that is placed in the oe. u can also create rects through custom script. u can create regions to.
a region is one or more rects in basically a group.

 

[MasterTrainer]

So a 'region' is a 'rect group' is that right? Oh and what is OE?

[deathismyfriend]

Thanks Hera and yes master trainer a region is basically a rect group.
