 |
|
Is there curently anyway to make semi-transparent images work in lua?
For example, I would like to make a menu that I can still see the background image through. Also, can anyone tell me how to make a button not work, maybe like pad:left(nil) or something.
Thx for all the help, and great work on Lua!

there's no way to do real transparency yet, unless you write your own blending routine, which would be very slow...

Anyone got any suggestions for the button problem? Im trying to make it so that when my task menu is opened by pressing cross that no other buttons work untill the menu is closed with the cross button. I have tried different things, such as:
| Code: |
if pad:left() then
pad:left() = nil
|
... but these all give me errors. I am getting all bent out of shape cause i cant figure out this little problem. :(

sounds like you're going about things in the wrong way..
just make a loop that only checks for the buttons you want.

Shine posted a demo how to access pspGL from Lua some time ago, maybe you want to take a look... |

that demo was for an experimental build of luaplayer. you can't do that with regular luaplayer, afaik.

That worked, thanks... Don't know why I got stuck on something so simple.

You could try refresh interlacing the images to get a psuedo 50% alpha look... try blinking the image onto the screen every other frame. Not sure how this will look but its an old trick.
Another option would be to blit every other line of the image intended to be mixed onto the screen buffer. This, if done with horizontal lines, would probably not be terribly intense to do... a basic interlace blend.
Been meaning to try both of these. They are far from ideal but could get you psuedo blending/transparency until a real GL hook is implemented. |
