I'm not sure what could be wrong with the strlen checks, as eff should
have been 2. But if you want to store the actual int value of each digit in
dur, eff, and targ, for example: 'shield self 321' would be dur=3, eff=2,
targ=1. If that is the case, strlen is not what you want to use. There
are a few ways you can get the value of each digit. These will only work
assuming you can only use 0-9 for each power up, ie: you can do 2101,
dur=1, eff=10, targ=1.
The first one will use some charctrer arithmetic:
dur = *arg2 - '0';
eff = *(arg2+1) - '0';
targ = *(arg2+2) - '0';
In this example, the pointer notation will get each digit of arg2 and the
subtraction of '0' will basically convert the character to an integer.
Or you can use atoi and some equasions:
number = atoi(arg2);
dur = number/100;
eff = (number/10)%10;
targ = number%10;
That should do it for ya. I like the first example the best, but they both
do the same thing, so use whichervr you prefer. Hope that helps.
