[JASS] How to do shockwave

[You Win]

Anyone know how to do shockwave, the same as blizzard made..
*NOTE: the wave of shockwave did not stop at the target position unless it reaches the maximum range..

Please help me on this.. thank you very much..

 

[Troll-Brain]

this spell use an oriented rectangle (not just a rect).
i've done a system to define an oriented rect with 2 locations and a width but i must add methods and place many comments ...
So i think i will post it at the end of the next week.
i will recreate the shockwave as an example of what the system can do.
But btw why you don't just use the schockwave with a dummy unit ?

Well cause I am new to JASS and i wanna learn more before i can actually good at it.. I mean i try to write my own JASS and it ended up a lot of problem... Oh well..

Can you explain how oriented rectangle and rect works? Hope you don't mind since i am new to JASS

 

[Troll-Brain]

it's virtual, i don't create rect but just play with 4 locations.
i mean normal rect are always like that :

A           B            

C           D

A      B



C      D

so for a rect you need to know only xMin,yMin,Xmax,yMax.

there is an ugly picture :

the three is an oriented rect.

So errm how we going to use it on shockwave? Shockwave is a line not a rectangle right?

false, try to put many paused units with 1 hp and do the whockwave on this, you will see the rect

Ya but the shockwave didn't just kill all the unit in the area instantly right? It die the shockwave touch the unit right?

And another question is how we going to get the min and max for x and y?

ofc, but it's a small rect which move and hurt units on this.
hard to explain my system without the code.
But for a rect you have these functions like that :

native GetRectMaxX              takes rect whichRect returns real

and the same with Y and Min

Instead of rect, can i use like circle? So when will you help me on the jass? Kind of need it as soon as possible haha.. Sorry to trouble you

native GroupEnumUnitsInRange takes group whichGroup, real x, real y, real radius, boolexpr filter returns nothing

Can you help me do the shockwave jass script please? using the rect ok? Thanks a lot =)

Create a dummy unit, and on a repeated timer, move it and do GroupEnumUnitsInRange to get the units around it. Damage these units, maybe do a special effect or whatever, and add them to a group which stores all the hit units so they don't get hit again. Destroy the dummy and stop the timer when it reaches its maximum range.

The problem with circles is, it can miss targets / hit targets twice.
Like this drawing shows (the black circles are targets).

In the first case (left), the spacing is one circle after another, and it might miss targets.
In the second cast (right), the spacing is smaller so you can hit targets on he end boundaries but it can hit targets twice.

So, if you are using circles, you will have to check if the targets were hit already once (it can be done in a lot of ways. The easiest one would be changing their Custom Value to something else for 1 second or so).

Attaching a group to the spell is much safer and not really any harder.

Shockwave is ofcourse one line with a range for picking up units and deal dmg to them!

acctuly damaging target if the touch the "missle" would be more realistic cause then missle is a wave of "force" and it should damage more then 1 time, also keep the damage low if ur running it on a .035 timer
