Yikes .. wasn't aware of that bug

Hi Ats, But the main problem is glGetUniformLocation that returns 0 :| It's weird that it returns 0, it should be -1 when something is wrong. All right, the square isn't showing up on Android because of the "f" in "0.0f". Oops, my mistake .. since it's GLSL i should have written ...

Hi Ats, The example i posted uses "Compatible" mode, which doesn't support shaders on Android. And in case you'd switch the example to ES2/GL3, the shaders need to be re-written ( a bit ). So, here's a ES2/GL3 version instead ( untested .. i don't have any Android devices lying around at t...

Hi Ats, Did you use ES2/GL3 for both the PC and Android version? Anyway, here's an example using glGetUniformLocation that should move a sprite around like a clock. <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor applicati...

Hi Ats, What I don’t understand is how glUniform1f sets a random value inside the shader. The glUniform function(s) set the value of a specific uniform variable of the shader that is currently active. It's the "location" argument that determines which uniform variable you're writing to. In...

Hi Ats, Can I pass a random number from the currently rendered model to its shader? That's what uniform variables are for :wink: Unfortunately, there's a issue with ShaderVariable. Since UseMaterial is ignored when the selected material is already active, any changes to ShaderVariable will be skippe...

Hi Ats, So I tried your last test several times, and for quite a while. It’s not crashing at all. Then I tried enabling and disabling GL_BLEND again, just to be sure. It randomly crashes at some point, every time. Yea .. it's not GL_BLEND specifically. Something related to ZExternalLibrary is causin...

Hmm, Sorry, your colored background isn't crashing on Android 64. So weird .. :? What if you swap the glEnable/glDisable(GL_BLEND) calls with two Materials that do the equivalent? <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="Androi...

Hi Ats, Have you tried other ( basic ) OpenGL calls to see if it still crashes on 64-bit Android? For example something like: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor application" ClearScreenMode="1" ...

Hi Ats, So I'll keep my array as is, since "Persistent arrays only supported for numeric data types". Perhaps your "Alphabet" example is just an example .. but in case it's a map for a font or name-entry dialog or something, you might as well store the ASCII codes instead. Howeve...

Hi Ats, That syntax can only be used to declare and initialize local arrays .. like this: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2"> <OnLoaded> <ZExpression> <Expression> <...

You missed a couple of them

- Array.Values
- Music.MusicFile
- SpriteSheet.SpriteData

Hi Ats,

Very cool! This took me back to TV shows where they had "trucage" or made-for-TV video games that you really wanted to play .. except this time you actually can

Hi Ats, Yep, it's only " / assets/" in preview mode :wink: Well .. that depends on what the desired behavior should be. In DOS & Windows a leading "directory seperator character" means that the path is "relative from the root of the current drive". https://learn.mic...

Hi guys, I agree, we should make it so that if you specify "assets/" then this should work on Windows too and be assumed to be a subfolder to the exe-file. Windows can normally deal with paths that have a mixture of forward slashes and backslashes. Would be convenient if ZGE automagically ...
