| Now I'm having an issue with it. =P
With the code using ch_printf, it's fine. But using sprintf, I get these warnings:
update.c:3806: warning: format '%d' expects type 'int', but argument 3 has type 'long int'
update.c:3806: warning: format '%d' expects type 'int', but argument 5 has type 'long int'
update.c:3806: warning: format '%d' expects type 'int', but argument 7 has type 'long int'
update.c:3806: warning: format '%d' expects type 'int', but argument 9 has type 'long int'
Doesn't make much sense, except ch_printf is being used and not sprintf. How would I fix those warnings? |

| | I think all you need to do is to use %l instead of %d, to avoid the warning. |

| | Oops, I left out the d. Yes, of course, it's %ld, because the l is a length modifier ('long') on the conversion specifier (d, the integer). |

| | Silly me. It's been too long since I did code with long int. Thanks. |

| | Worked fine for me in FUSS. Are you getting compile errors or something? If so, start a new topic. Keeps things organized. |

| A point of efficiency, even if it's a slight one. Smaug has the current_time variable declared globally and it is updated every game_loop, which is roughly 0.25sec. So this bit here:
current = time(0);
diff = current - boot_time
Could be done as:
diff = current_time - boot_time;
One less variable to declare and use, and one less function call to make each time the command is issued. It's little things like this to keep in mind for overall resource efficiency :) | | Top |

| It's true that that would be more efficient, technically speaking, but the gain would be negligible. time(0) is a very cheap operation and this function is not called very frequently. In a sense it's not even a blip on the radar in terms of efficiency, even if it is faster. If you think about it in assembly terms, it's clearer why it's not very important. One function call every once in a while is really nothing. If this function were called very often (as in several thousand times per second or even more), this optimization would be more important.
I would argue that it's important to use the global variable to ensure that you're operating on the same time units. If the time were to be changed and counted in, say, nanoseconds, then using time(0) would break things whereas using the global would be somewhat easier to fix. (Your end result would be off, instead of subtracting nanoseconds from milliseconds or something weird like that.) |
