I think I'm misunderstanding how to get colors from an Image within a Shader. I'm trying to get the trivial case working -- a shader that returns a color from the image. I expect the results of using the shader on a rectangle to be the same as drawing the canvas directly -- blue and green swirly neb...

Final Score: 193 This is awesome! Totally agree with what others have said about how nice the weapons are. Also agree it's a little hard to see which direction the ship is pointing. I really like the colors chosen. That and the hand-drawn look of some of hearts and X's reminds me a bit of GoNNER. Th...

I'll second what zorg has said.

to create an image: to delete The actual memory will be freed up sooner or later (up to Lua's garbage collection implementation)

You're on the right track by starting small with the scope of your game. The reason why I can't enhance your code is because I don't know what you want it to do better. Do you want it to be less buggy? Then pick 1 bug at a time and fix it. If you don't know how, you can google the bug or maybe post ...

Thanks for writing. Seems like a pretty good tutorial. On the whole, I prefer tutorials like this: http://tylerneylon.com/a/learn-lua/ But then again, I've had previous programming experience. I still would think a complete beginner might benefit more from following along from a video on youtube. Bu...

First of all, I love Downwell and am super inspired by it, too. I'm happy to see somebody else saw its potential as well! I'll echo what others have said: Frogfaller looks awesome! Looks like you've got the hard part (actually making the game) well under way. All the stuff about optimization is true...

This reminds me a lot of Nuclear Throne. Which is a huge compliment from me, as I live Binding of Isaac and other rogue-likes. So great job! The art at least seems to do its job -- the character, enemies, and pick-up-ables seem to contrast well with the background. I like the higher-res style you've...

Use a collision library to handle collision detection for you. I recommend bump (kikito) or vrld's hump library. You can find them in the wiki.

This way, you don't have to maintain or worry about most of the collision code, and can focus on how you want to resolve them.

This all being said... whenever I see hotspots/buttons/ui interaction implemented this way in a game or program it tears me up. I feel like, as a user, I shouldn't have to aim directly onto the button I want to click, I should just have to be close. Think about it like this: Imagine if in order to h...

I figured it out. I wasn't removing the mob from game.mobs table in mob:destroy. "self = nil" does not prevent game from calling mob:destroy every frame. So the 2nd time it gets called, there's no item to remove from bump world.
