Messing with the image stack

[muzzel]

package Test
import Image
import Unit

image array images

init
	let max = 100
	for n = 1 to max
		images[n] = createImage("ReplaceableTextures\\CommandButtons\\BTNPeasant.blp", vec2(0., 0.), 1., 1.)
	for n = 1 to max
		DestroyImage(images[n])
	createUnit(Player(0), 'hfoo', vec2(0., 0.), angle(0.))
	for n = 1 to max
		DestroyImage(images[n])

I managed to mess up the selection circles. They pop up at wrong units, dont disappear on deselection or sometimes a unit has two circles (as can be seen in the picture).
However i didnt manage to manipulate the hp bars, arent those images? Or are they just updated too frequently (since they have to adapt to the units health...)?

Awesome, lol

Cool.

Well, some things may be inherently part of the wc3 engine/hardcoded. Selection circles and shadows are very convenient as images since they are just centered at the unit's position and don't require a 3rd dimension. Hp bars are a bit more dynamic (e.g. when you scroll down they still face you, whereas images lie flat on the terrain). I think that hp bars are just billboarded models.

One neat thing that may help:

function I2Image takes integer id returns image
    call SaveFogStateHandle(hash, 0, 0, ConvertFogState(id))
    return LoadImageHandle(hash, 0, 0)
endfunction

You can iterate through a loop starting at 0x100000 and increment by 1. iirc you can just check if I2Image(<id>) != null, and then that means there is an image in that slot (that handle ID).

Yep that sort of stuff happens when you destroy shadows of units.
But you can hide them (and/or make it transparent i don't remember) and then it's fine.

I know about shadows, but my intention was to manipulate hp bars...

Meh was worth a try.

I also think that hp bars are models, and yes that was worth a try but i don't think you can catch other "hidden" image than shadows.

You can aslo try with lightnings/effects.

Awesome find.
I will actually find this useful. ^^
