Is there a plugin for obtaining the frequencies of audio output? I want to make a equalizer visualizer effect.

Did you stretch the solid blocks for one floor instead of having many solid blocks? If so, you are doing correctly.

Tiled backgrounds are better with smaller sizes. Let's say 64 x 64 to 512 x 512. But be sure to check performance on mobile devices. Some older smartphones will slow down badly with larger tiles.

Try to slice your sprites to be smaller. Not only it uses less memory. It also allows greater modularity.

For collision polygons, use a sprite specifically for "solids" in your case. Expand them to fill the area as neccessary. You can turn them invisible in your game.

I want to have some values regarding the frequencies of the audio output. Is there some sort of plugin that allows me to get the frequency of the audio output?

Correct me if I'm wrong. If all the characters of the font have the same space, like Courier font, then this shouldn't be any trouble, but for fonts with characters with different spacing, adjusting the spaces around could be a pain.

I want to talk about the current trend: Tizen competition

While we have been stressed all the time that mobile devices have limited capabilities, we can't really say whether we will have a performance hit until we tried the actual device. While the post on Tizen competition claimed that it got 93% scirra mark, I'm still looking for the following answers to ensure smoothness of my app on Tizen:

1. Are there any say on maximum number of instances and sprite size, etc before fps dropped? I got several 128 x 128 sprites, and these will hit performance greatly for older smartphone, but the number of these sprites should not exceed 50. I also got myself some more tiles object for filling in the background.

2. Is it possible to say that, from number 1, I can run 60 fps with 50 sprites with the size of 128 x 128 with at least 1280 x 720 resolution on Tizen OS? Exclude event sheet for now.

I've read all the tutorial and manual about sprite fonts. It's a neat feature, but one question: do we have a tool to convert regular font directly into sprite font format that C2 understands? I see that it's just a texture with all the letters and such, but to work faster, I would prefer a tool.

Imagine you are in a disco nightclub. You have loud disco music, the crowd and all.

Now, imagine you walking out to back of the nightclub. You could still hear the music and all, but all the sounds are contained in the building, so how you hear it will be different from inside.

So the question is this, if I want to give the player this impression that a disco nightclub is behind him, what are some of the filters I must use on the playing audio?

Just curious here, are the number variables we are using double, float, or something else?

How many digits of number can we go for, until we start to have a little round off error, precision error, etc?

I see that these days, computer screen pretty much have 16:9 ratio, you know, those 1900 x 1080 resolution and what not. Mobile devices also have widescreen for landscape perspective. But there are various aspect ratio for many devices. iPhone 4 is 640�960 and the iPhone 5 is 640�1136. All these are different aspect ratio. Ashley has already posted a tutorial regarding this matter at scirra.com/tutorials/73/supporting-multiple-screen-sizes

I am curious What aspect ratio do you usually use for your game? And I also would like to know what is the most famous aspect ratio right now, for mobile devices (tablet included) ?

Aha, do you know the performance of that?

Let's say I got 100 birds on screen. The player must draw a line to cover x number of birds and close the line to form a loop. The loop does not have to be a circle but no part of the line shall intersect itself. It could be shaped anything, BUT the line must be closed.

Now, my actual problem is this: with this closed loop that can be shaped anything, how can I count how many birds are actually inside the loop? The birds' positions scatter randomly and they move around.
