===AGS do-while loop=== | |||
One of the "missing" loop structures in AGS is the "do-while" structure which in '''other''' languages looks like this: | |||
int i = 5; | |||
do { | |||
blah(); | |||
i++; | |||
} while (i < 4); | |||
The point being to ensure that the loop is run at least one time, regardless of the condition. This can however be simulated in AGS using the Game.DoOnceOnly function: | |||
int i = 5; | |||
DateTime *now = DateTime.Now; | |||
while ((i < 4) || (Game.DoOnceOnly(String.Format("%d", now.RawTime)))) { | |||
blah(); | |||
i++; | |||
} | |||
In both cases (AGS and the pseudo-C-style programming) ''i'' would have a resulting value of 6 and the loop would run exactly one time. This bit of trickery is possible thanks to Game.DoOnceOnly accepting unique ID strings. If you needed to perform more than one do-while within a single second you would have to do something else, perhaps just appending a variable to the end of that, but you should get the idea now. | |||
