Remove shadow

[kingkwong]

I have GetLocal() player which makes a unit invisible to some players
How do you remove shadows from a unit?

 

[nedio95]

From the Object Editor:
Art - Shadow Image (Unit)
Normal/Flying >>> None


Or if you mean during gameplay... There is no direct way to edit that (or is there?) so replace the unit with a copy of it without a shadow.

maybe you could have a dummy aura, which attachs a "shadow" model on origin, then remove/add the ability when you need to

I have a few units and was hoping not to have to create a copy of each unit.

Thats a pretty original idea, I will try that now. Get back to you after I have tested it. What model is the shadow and how do I access it?

EDIT: Still can't find the model for shadow so I can't really test this idea. I can't find anything in search either on how to find shadow

There is a very hacky way to hide a shadow of a unit via images.
It requires JASS script, though and also requires you to remove/recreate said unit to hide the shadow.

If you are interested, just search "hide unit shadows".

EDIT: I searched it for you:

// Credit to Deaod, edited by Maker
     private function CreateUnitWithoutShadow takes player owner, integer uid, real facing, string shadowfile returns unit
         local image i = CreateImage(shadowfile, 1, 1, 0, 0, 0, 0, 1, 1, 0, 3) // creates a dummy image
         if GetHandleId(i) == -1 then // if the new shadow is invalid, abort, it can screw up the game
             debug call BJDebugMsg("CreateUnitWithShadow: Invalid path for new shadow!") // it could also be caused by an imageType of 0, but thats a less common cause
             return null // since the image is invalid, we dont need to destroy it
         endif
         call DestroyImage(i) // destroy the dummy.
         set u = CreateUnit(owner, uid, CREATE_X, CREATE_Y, facing) // create the unit. this also creates a new image which functions as the shadow of the unit. The shadow will use the ID of the dummy image.
         call DestroyImage(i) // destroy the shadow of the unit
         call CreateImage(shadowfile, 1, 1, 0, 0, 0, 0, 1, 1, 0, 3) // this creates the new shadow for the unit, note that i dont need to overwrite "i" as the id this image will get is predictable
         call SetImageRenderAlways(i, false) // Hides the shadow
         call SetImageColor(i, 0, 0, 0, 0)   // Makes the shadow invisible
         // no need to null "i", as images dont use ref-counting
         return u
     endfunction

I don't really want to replace the unit as it can sometimes mess with my other triggers.

Maybe you could use this kind of method to store the shadows of all units and then hide a specific unit's shadow by loading the right image from the list.

 

[Zwiebelchen]

What Wietlol said should work: remember that the shadow in this method is only "removed" by making it invisible with SetImageRenderAlways.

All you need to do is collect all images on unit creation and store the images as a variable array (use a unit indexer), then you can hide them on demand.

This is a bit complex for me atm. Unless you can give me an example of what the trigger might look like, I might just stick to creating another dummy unit copy which has no shadow.

I also would like to know what the shadow model is if anyone knows.

There is no shadow model. Shadows are images. This is why the above mentioned method works.

Images in JASS
This has a small snippet at the bottom that talks about the shadows of units and how to assign them without bothering with the units themselves.

Ok, going to try this out when I have time. Looks like I have to use Jass for all the things I want to get done. Anyone know a good place to learn the basics. Converting GUI into custom text doesn't really tell me much of what is going on.

tutorial section of JASS is filled with how to use it.
