I just finished up the sample app for Lesson 7 in my Business Apps Using Corona SDK course. Tomorrow I’ll be recording the tutorial videos for that lesson. Here’s a screenshot of the sample app: End of day Monday I’ll take the “pre-launch” price down and put up the final price ($15 higher), so if creating business apps using Corona SDK...

Someone on the Corona SDK forum asked about using multiple variables to create a string. For example: local a = "The" local b = "cat" In essence they wanted to print a and b together to say The cat (but with a line break between each word). The easy answer is to just use Lua’s concatenate symbol along with the variables and a newline...

Yesterday I made enough progress on my app for the Techority 48-Hour Challenge that I was feeling *very* good about things so I posted a video showing what I’d done. But then late last night I came across a limitation in Corona SDK that has stopped me in my tracks. I knew choosing the different parts of the picture to color was a little funky so I knuckled down...

Okay, the little widget I posted about earlier works like this: You tap a part of the picture to color and then add or subtract Red, Green, and Blue from that part. Every part of the picture starts right in the middle — halfway between black and white. If you want a part to be red, you’d add red and pull out green and blue. If you want a part to be...

This morning at 2AM I posted a progress video to YouTube and headed for bed – but realized what I was planning would NOT work! Filling an object with one color was fine, but mixing multiple colors looked like it would be a nightmare/impossible. So I sat down and worked for another 3 hours to change the “color delivery mechanism” and it will work! It...

So I decided to go with something I spec’d out last October — walking around the toy section of the local Fred Meyer store looking for inspiration (about an hour before the challenge started) I spotted a bunch of coloring books… …and remembered the game idea I’d posted on Game Dev Nation several months ago. So I came home and decided to...

I just got out of the store and I think I’ve come up with the idea I’m going to do for the 48 hour challenge. What’s weird is that it’s an idea I came up with several months ago and blogged about on one of my other sites. But I never did anything with it other than spec it out but that’s okay because if I had worked on it I...
