ImageSearch not reliable (Diablo 3)

[Baki]

Hello,

What i want to do:
-search for an Image in the upper left part of the screen
-if image is found press 3
-if image is not found press RButton

Here's the code:

Code: Select all

*space:: 
While GetKeyState("space","P")
{
ImageSearch, outX, outY, 0, 0, 500, 100, C:\rathma\10mages.bmp
if ErrorLevel = 1
{
Send {RButton down}
Send {RButton up}
}

else
{
Send 3
}

}
return

What i want to do:
-Search for an Image in the upper left part of the screen
-If image is found press 3
-If image is not found press RButton

If the image is not present all works as expected - it sends "RButton". If the image is present ahk sends a mix of "RButton" and "3" - in other words: it does not detect the image reliable. I tried adding *n (2-200) but nothing changed. Also tried the .png format.

Ingame Screen: i want to look for the Buff in the upper left corner with the "10"

This is the image i use to search for:


any ideas why it does not always recognize the image?

try this.

thanks again for your answer, Capn Odin. Ahk does not recognize the modified image at all.

Anybody got another idea what i could try to make this work correctly?

i have experimented a bit:

-if i search a screenshot (not ingame) it works flawlessly
-no matter what image i am searching for while i am ingame, it always gives mixed results. found, found, found, not found, not found, not found etc.

Edit: did some more testing: works while i am in the "lobby". as soon as i enter a game it will always give mixed results

My immediate thought is that there may be shadows passing over and behind the image. This is what makes games pretty to the eye.
You can try work around that by including a variation on the color. Someone built a function that gets the average color for an area and you might be able to use that but the screen looks a bit dark for that to be of much use.
Another potion might be to rather look for a set of unique pixel colors at specific locations.

I had an interesting one where multiple images were needed and they were checked after each other, turns out the images all looked the same but the actual colors were different. A color looks blue because the color next to it is green when it is actually something else.

use cheat engine to find the value/flag that changes and read it with ahk

thanks for your advice, grant.

pixelgetcolor gives exactly the same mixed results

A cheat engine is not an option for me. ahk is as close to cheating as it gets for me

did you make it work?
