shader differences on mac

keszegh

I have a shader which seems to crash my mac export without any error message. it works with no problems on windows. is there any common rule of using shaders on mac one has to keep in mind (like there are some specifics for android)? btw it does not immediately crash, just after a while, it's a bit random (as incidentally is one parameter of the shader).
thanks

i can share the shader as well, but currently i'm not yet sure if all my 'special fx' shaders have this issue or only one of them.

fyi setColorTransform does not give the same results on pc and android

self.mybgbmp:setColorTransform(0.5, 0.5, 0.5, 1)

@MoKaLux , what is the difference?

(although i'm now into mac, and my issue is more serious than 'different', as it crashes on mac)

the colors are more vivid on my pc screen (I have set my android screen to 100% brightness to compare).
Sorry I didn't answer your question, that was just an info

@keszegh you can try to test your shader in KodeLife for example and see if it throws any errors? If not then, perhaps its not shader problem...?

keszegh

so here are the relevant files for my glitch shader. perhaps you can test/spot issue with mac?

i tried to convert the code so that kodelife accepts it but even when it threw no errors, nothing was visible.

edit: i've managed to change the code so that it works in kodelife, i have yet to test it on someone's mac.

keszegh

it seems now that maybe the crashes are not due to the shader, it's hard to decide as there is no error log.

on the other hand i could not test my shader on kodelife as version 120 is accepted on windows but not on mac and that's the version which accepts code that is most similar to what gideros accepts.
