The future is awesome.

 

[DarkePacific]

Wow!! Awesome. Never could've imagined a system like this being implemented in wc3!

 

[Marchombre]

That's awesome !
Will be really great to see what can be done with those spells

Some ideas to explore this even further:

Extend to destructible

Some spells would destroy trees etc., so it would be great to know what you're hitting

Open to custom spells

One might want to have a aimer system for custom spells (maybe something like a shockwave which would go forward and backward).
From what I see, that would mean that someone could give your newaimTrigger a data object, containing AoeStart, AoeEnd, etc. but also adding a list of angles that would allow the mapper to create a spell that shoot in multiple directions.

Adapt when targeting out of range

This one is tricky, and I honestly don't know if something that would not end up really weird could be done.
When using your test map, I targeted a unit that was out of range, which means the caster had to move on order to cast. Thus the LineAimer doesn't show the unit that will be affected.

I think the simple way is to change the line color when target is out of range, which will warn the user that the caster will move.
Or we could go for the hard way
Something like a preview, which would show the caster position and the range/targets affected from here.
I don't know if I explained well, so you'll find a picture attached (Yellow is what we got now, red would be the "preview")



I hope I didn't scared you away with those ideas

English isn't my native language, so I might not explain well. Feel free to ask for any clarifications

    function isInTargetingMode takes nothing returns boolean
        local integer index = 0
        loop
            if BlzFrameIsVisible(BlzGetOriginFrame(ORIGIN_FRAME_COMMAND_BUTTON, index)) then
                exitwhen true
            endif
                set index = index + 1
            exitwhen index == 12 // when 12 is reached no button is visible
        endloop
        return index == 11 //when the loop broke in index == 11 its targeting mode

    endfunction

I'm not sure I understand this. So when you reach index == 12, that means the code has looped through all 12 frames on the command card (ORIGIN_FRAME_COMMAND_BUTTON 0 to 11) and found all of them to be hidden? Does ORIGIN_FRAME_COMMAND_BUTTON 11 stay visible during targetting or something?

They are only visible when the command card uses the slot. During Targeting only the cancel command is used normaly the last button, which is index 11. This assumes one did not change the cancel position.
When it reaches 12 no button is used by the command card.

Ooh, so you check for the cancel button. Smart. I wonder if I could use this technique for detecting when selecting which building to build from the command card.

Also, why not detect the cancel button after a mouse click event instead of constantly?

Looks great!

Does Line Aimer works with 1.31? Just want to confirm if there's any Reforged exclusive natives here

 

[Tasyen]

Sadly requires a event that was added in reforged .

Great system.
Though i couldn't get it to work.
Imported the Jass folder and .slk and changed its path as well as tried inserting both "A01H:ACsh" and "A01H" versions of a custom ability into the "LineAimerSkills vjass" trigger. I tried even the basic Shockwave ability but it just wont work.
Not sure where i went wrong.
