ifrnd <value> { do something } else { do something else }
An if condition stating the probability of it 'doin somethin!' in this case.
A <value> greater or equal to 255 corresponds to a 100% probability that the first block is taken. With a <value> of -1, the "else" block is taken every time. (A <value> of 0 means taking the "if" block once out of 256 on average).
The math can be counter-intuitive, putting it simple:
- ifrnd 0 will return true 1/256 of cases;
- ifrnd 127 will return true 128/256 of cases;
- ifrnd 255 will return true 256/256 of cases;
This command must only be used in synchronised code or you will cause desyncs. for display code use displayrand instead.
