blank spaces in the pictures

Jacko

Hello,
Is there any posobility to ignore blank spaces in the pictures, I mean

SinisterSoft

Use an art program to make the blank transparent then save as a png, or if you know the rgb value of the blank area you can set the transparency when you load the texture.

Jacko

i donk know if this "hack" would work on buttons (i think it wouldnt) but in your gameplay if you want to ignore the blank areas you could cut your image in three pieces and load them one next to the other in order to create three bounding boxes.

So gideros no matter what, see that blank spaces?

In general the answer is no, but soon the next version of Gideros using OpenGL ES 2.0 could be able to do that ( @john26, any plans on implementing this?). Until then, see this other thread for partial solutions (representing your non-transparent area with a polygon):

Use Gimp and convert blank to alpha.

Did not work.

I use transparent rectangles to do that sort of thing, positioned over the graphic and check for those being touched. In your podium example I would have three rectangles, one for each position, with the rectangles matching as closely as I can the bits that I want to be touched. I usually make the rectangles semi transparent while working on this sort of thing so that I can check their positions.

It's really a variation of what @dreiko65 suggested above where you don't have to chop up your graphics.

In addition to the link that @keszegh gave, here is another solution for round buttons to ignore transparent parts.
