Just a minor thing: if I add one of the new color properties to an object and give it an alpha value less than 255, if I adjust the value again with the color select dialog, the alpha is ignored and set to 255.
This is using Tiled 0.17.0 & OSX 10,11.6. Unfortunately I don’t have a Windows box handy to test this.
Thanks for noticing! I can reproduce the issue also on Linux and Windows, and it seems to have been there since a long time (tested with map background color in Tiled 0.15.0). I’ll look into fixing this for Tiled 0.17.1.
If you look into this, I’ve noticed another issue with Tiled 0.16.1 when exporting to JSON: ObjectGroup color is exported as “#RRGGBB” (there is no alpha component), even if I can set the alpha channel from the color picker. I don’t know if this is desired behaviour.
