System Knockback (GUI)

[Tom_Kazansky]

Knockback System
by Tom_Kazansky​

There are many Knockback Systems but most of them are written in Jass.
I make this system because GUI is easier to understand than Jass ("easier" not "easy")

Some informations about this system:
- easy to use (well, of course) (but Romek think It isn't )
- use 1 timer (how could I use many timers, GUI )
- changeable "arguments"
- it's MUI and a "stand alone" system

The triggers:

Implementation Instructions:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Copy and Paste the category "Knockback System"
Remember to check: File \ Preferences \ General \ Automatically create unknown variables while pasting trigger data.

How to use:
¯¯¯¯¯¯¯¯¯¯¯¯¯
To use this system, you need the following lines:

Set KnockbackCall_Unit = <unit that you want it to be knocked>
Set KnockbackCall_Dur = <total duration of knockback>
Set KnockbackCall_Dist = <distance of knockback>
Set KnockbackCall_Angle = <angle of knockback>
Set KnockbackCall_SFX = <knockback effect, put an <Empty String> if you don't want any effects to show>
Set KnockbackCall_DestroyTree = True <If you don't want to destroy trees, use "False" )
Trigger - Run Knocback Call <gen> (ignoring conditions) <- do not change this line


'KnockbackCall_Unit' will be knocked back 'KnockbackCall_Dist' over 'KnockbackCall_Dur' seconds towards 'KnockbackCall_Angle' degrees.

you got so many variables...

I think mine is better
http://www.thehelper.net/forums/showthread.php?p=983349#post983349

all you need to do is every time you want to run the knock back, increase the Knock_count by 1, set the angle where you want the unit to slide and add him to the group

the group is universal and can be used on any knock backing spell
for instance, I have made a knocking water form that knock backs any unit along the way while dashing just by adding the unit to the group

 

[Tom_Kazansky]

yes, many variables are used, but it's for the sake of "changeable arguments"

your Knockback, the speed of the knockback are constant and also the duration of the knock depends on level of an abilitiy

and I think there are better uses for the "Custom Value"

 

[Romek]

> easy to use (well, of course)
So you think your huge variable and trigger running thing is easier to use than:
Custom Script: call Knockback(udg_Unit, distance, speed, trees) ?

GUI does definitely not make things easier. It's harder to configure too, as vJass systems always have configuration at the top of the script.
Can this accelerate/decelerate the units?

GUI is also much less efficient, and more difficult to read. You can't really say that the code is easily editable and customizable.

I wonder how many instances of this an average computer can have running before it starts to lag.

 

[Azlier]

>easy to use (well, of course)

I say it's overly complicated. I do find the vJass versions to be much faster and easier to use.

>GUI is easier to understand than Jass

I find GUI so confusing.

 

[tuantai120]

i think system always easy to use but this system so long
whatever, thanks a tom

 

[wraithseeker]

This is a great system for persistant GUI aka humans who does not want to fall to the plague of the cult of the damned. I don't see why this is bad, it just needs more documention as it seems hella confusing for me, I can't read scrolls of GUI text sorry.

Some more sample spells perhaps? One, seems too little. Also, why don't you use locals in GUI to MUI it easier and remove leaks.

Pure GUI is badass. Anyway, nice system for GUI people + REP

 

[Tom_Kazansky]

>why don't you use locals in GUI to MUI it easier and remove leaks.

I don't get what do you mean by "to MUI it easier", but for removing leaks, those variables are used instantly, so I think there shouldn't be a problem.
-------
I'm a JASS-er so my method of making this GUI system maybe a little "JASS-like" ( "too many" arguments :nuts: )
---
I hope my system will be useful for some GUI-er

agreed - and this system is harder to use then any JASS system around - even for GUIers - not to mention less efficient, less robust, etc.

 

[RMX]

Well i have seen this system before it's really i mean reallllllllly close to the system in Hiveworkshop.com created by Paladon and it's MUI....

Maybe u have changed it a little so no body can notice ...

If it is urs well i will give it 5/5 like i gave Paladon .

This system is bulletproof and does not lag at all coz it uses alot of variabel wich make
the Trigers more efficient

 

[Andrewgosu]

In the "Knockback Execute" trigger, you can set "(Integer A)" to a variable to save quite a lot of function calls.

I might as well approve it for the sake of GUI users, but I agree with the rest:

JASS systems are actually easier to use, not to mention the gain in efficiency.

 

[Tom_Kazansky]

Andrewgosu, thanks

>In the "Knockback Execute" trigger, you can set "(Integer A)" to a variable to save quite a lot of function calls.

done, updated

 

[Cookiemaster]

Hey! This system is limited on only 8192 units! >:O

Also, this system seems somewhat abusable for players. You can use it as a rigged stun by knockbacking someone against a wall. (Or sometimes shooting people through it if the speed is too great!) And you can stop someone by standing in the way. (Blocking it with a tiny group of units.)

It would be a nice possibility to see in a knockback system the possibility of passing knockback onto units the knockback unit collides into while flying over the place. (Even though this would cause quite lagg when a lot of units are standing together.)

 

[Tom_Kazansky]

>Hey! This system is limited on only 8192 units!

I doubt that you would use this system for about 100 units

>It would be a nice possibility to see in a knockback system the possibility of passing knockback onto units the knockback unit collides into while flying over the place. (Even though this would cause quite lagg when a lot of units are standing together.)

that system sounds like a ultimate spell for me

mine is just a simple GUI Knockback system, so anything beyond that should be expected in JASS

It's not so hard to make, apply some physics, do a pick every unit group in the unit integer loop, pass around some knockbacks, and done.

 

[Squishinator]

Would it be easy to alter this so if a unit runs into it it will be moved back too? Yours isnt doing that (at least not for me). My spell i am trying to do is like thunderclap but lasts for like 7 seconds, and creeps keep running in and attacking my casting unit. >.<

 

[Pyroflame]

Very well done system, in GUI at that too.

 

[Gladius_Tito]

This is a great system for people who can't use vJass because of technical difficulties (AKA me).

 

[FhelZone]

Used it on my map, extremely useful and easy to customize, thanks for posting this.

 

[Devrak]

Very easy to edit, it will really help in my map.

Thanks! :thup:
