| // Counting frames per second | |
| // ========================== | |
| // | |
| // My basic strategy is to divide the time taken over the | |
| // last n frames and return n seconds / time seconds. | |
| // | |
| // I must provide a method to say that a frame is done, so that | |
| // the time can be recorded and a method to get the current FPS, | |
| // and I must store the last n + 1 (because of the fencepost | |
| // problem) times. |
In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.
For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.
