Resolved by Rich!

Can anyone give me info on how to program an If-Then sequence? Ex. If the robot sees a red ball, it will stop, if it sees a green one, it will go forward. Also a screenshot of the programming would be helpful. Thanks!

I have covered IF statements in a few topics, I'll list them in a sec. But to answer this question is very simple;

First you need to make sure you have the camera control set up for colour detection, this will give ARC the global variable called $CameraObjectColor

Then your script would need the following IF statement

Code:

IF($CameraObjectColor = "Red")
  Stop()
ELSEIF($CameraObjectColor = "Green")
  Forward()
ELSE
  # Neither colour detected
  Print("No colour detected, awaiting colour to proceed")
EndIf

Here are the topics I mentioned which may be of benefit to read through.

An Introduction To Scripting

I've also posted a few other scripts which use IFs, my Ping Roam has a lot of IF statements. As do most of my files on the EZ-Cloud
