Alpha blending bug on Android?

Welcome to our brand new Clickteam Community Hub! We hope you will enjoy using the new features, which we will be further expanding in the coming months.

A few features including Passport are unavailable initially whilst we monitor stability of the new platform, we hope to bring these online very soon. Small issues will crop up following the import from our old system, including some message formatting, translation accuracy and other things.

Thank you for your patience whilst we've worked on this and we look forward to more exciting community developments soon!

  • Hello,

    Is there an number objects limit with alpha blending option?
    In my game, my UI appear progressively with the alpha-blending. All UI objects are in the layer number 4 (15 objects ). On windows, all work fine. But on Android, some objects (lasted create) don't work with alpha-blending.
    If I remove bugged objects in layer 3 or under it's working. But don't work in layer 4 or upper.

    I have already tried a lot of things. I recreated the buggy objects and modified the code. I don't know where the problem is...

    (sry for my english)

  • Thx for your help. I wasted several days on this problem.

    Please login to see this attachment.

    On windows, the ui appears well when the ball is in the middle of the screen.
    But on android, the 3 nuclear symbols at the top left have no alpha.

    When I simplified and cleaned up the mfa to send it, I noticed that there was an undeletable ghost object called "white_fade".
    May be the origin of the problem?

    IIRC ghost object is fixed in 292, although sometimes you still got one, but if you save and reopen your project fusion will automatically remove this corrupt object——or it's refered somewhere, try using find all to figure it out.

    I did some tests and Blend Coef was supposed to work...


    Yes I really don't understand... :/

    What do you mean by using "find all"? Is it a tool?
    I have seen a few topics on ghost objects. I'll try to find a solution tomorrow.

    Thanks for your answers!
    I hope someone has a solution...

    Find all is a 2.5+ feature, which allows you to search through each corner of your project.
    As I said before, fusion will automatically remove ghost objects when loading mfa, so if you still got these objects after saving&reloading, they maybe not a ghost object but a normal object you refered somewhere but you forgot, that's why I recommand you to use find all to figure it out.

    The icons under a users name show what versions and DLC for fusion a user has. MOuse over them to see what they are. The little orange one is for 2.5+ DLC. OP does not have that.

  • It seems the problem is caused by the "ui_barre_vie" counter object. If you move the "vie_ogive" objects behind this object, then this works (use the Order / Backward One command in the Frame editor to change the position of the object in the creation list). I'll ask Fernando to check why bar counter objects cause this issue.

    PS: I can't remove the white_fade object neither. As defisym said Fusion now automatically removes them when this happens, but apparently there is still a case where this happens... First time I see one for 2 years, must be rare.

    Oh, that's why all my new created objects didn't work. They were created above "ui_barre_vie". It works with your solution now. Thank you! :)

    I also noticed that if I use a more recent version of OpenGL in my android export, there are no more bugs. (OpenGL ES 3.0 instead of 1.1)
    But I guess it's better to use your solution and keep version 1.1 for more phone compatibility??
