Replace Color Bug only when compiling for Android (fine in Windows)

[DiegoArthur]

Hello all.

I was creating some temporary buttons for my android game and wanted them to have different colors, so I used "replace color" option.

This is the screenshot on Android (notice both blue circles, they aren't the same actives):

So I created the event to change the color of one blue circle. This screenshot is the game running on Windows after code implementation:

Then I compiled to Android and this is what I got (that Steam logo comes from a counter that I created):

This is the code. If I delete the second line, no Steam logo. If I leave it there, Steam logo shows up.

Replace Color is not coded in Android due the low performance behave in android devices

You could probably use RGB coefficient instead for a recolour of a single/mono colour object. RGB coeff works in Android.

Thanks for the tip. Will check it out.

No worries

Although if replace colour did work on Android, it would certainly save us Android developers a lot of headaches!

Even better would be the ability to paste active picture objects into the background or be able to somehow blit active pictures to a surface, but I know that's been asked a million times already.

a slow performance of this in android will sure will get more headaches to all.

Fernando,

How slow was the replace colour function when it was being tested? Was it still very slow no matter how many times it was being called per frame? I wonder if it could possibly still be useable if it was only called during the "idle" phases of an application..

this action is synchronous, you ask for it and is done, it can not be done in idle time , this take time of CPU and this affect severely the loop time I have not an answer for you in secs, but just consider that loading a bitmap in HD format in some device take 200msecs, in android the concept is not like PC, you must preload sprites and used, is in my todo list, trying to make it work with blend coefficient

That's something that we really miss. On Windows Phone it was working pretty well with XNA exporter. THis alloyed to create a single sprite and customize it with replace color to create different versions. Really perfect for customization.
Actually i'm using RGB coef on a shade of white for my main character, to be able to fully customize my character, i need to use 9 sprites...

With Replace color, i could get rid of all the white sprites...
