Looking for a method for flipping bidi (Hebrew) text so it would be displayed correctly in AndEngine

阅读更多关于 Looking for a method for flipping bidi (Hebrew) text so it would be displayed correctly in AndEngine

问题 I've been lurking around the web for days trying to look for a code implementation (Preferably Java) for flipping Bidi text so it would be displayed correctly inside platforms that do not support Bidi text text out of the box. (Such as AndEngine). The optimal solution would be a method that I would provide it with Hebrew text, and it would return its content flipped. I could do this by myself but it's getting complicated once it gets to mixed strings of both English and Hebrew text, as well

openGL drawing distorted sprites (images) in psuedo-3d perspective

阅读更多关于 openGL drawing distorted sprites (images) in psuedo-3d perspective

问题 Alright so this is going to be a doozy to explain. I'm making a very basic "pseudo-3d" racing game for Android using AndEngine (and in turn, openGL - I think). I don't believe using AndEngine really has anything to do with this problem though, because I'm directly accessing openGL functions to accomplish my drawing. Anyways, I copy-pasta'd some code that allowed the normally 2d AndEngine to have a 3d perspective (tutorial for such can be found here. This works pretty well, and I also don't

How to pop up 'new update available' dialogue, when user starts my app(android)

阅读更多关于 How to pop up 'new update available' dialogue, when user starts my app(android)

I made a game using AndEngine and I have made different updates three times and uploaded in google play store. I see that Google does provide a update notifications, but most of the people don't read the 'available updates' notification Google provides. So When the users start my app, I want it to pop up a dialogue such as "A new version is available. Do you want to update?" and upon clicking the 'yes' button, it will link to the google market of my app. Is there any way I could implement such device?
