4.7) Conditional Statements

Netlogo provides the usual range of commands for conditional statements. They are: if, ifelse, and while.

If statement: (if condition reports true, runs commands)

if condition [ commands ]
  if xcor > 0 [ set color blue ]

Ifelse statement: (reporter must report a boolean (true or false) value, if reporter reports true, runs commands 1, if reporter reports false, runs commands 2)

ifelse reporter [ commands1 ] [ commands2 ]
ifelse pxcor > 0 [ set pcolor blue ] [ set pcolor red ]

While statement: (if reporter reports false, exit the loop, otherwise run commands and repeat)

while [reporter] [ commands ]
while [any? other turtles-here] [ fd 1 ]
