I ma trying to learh App Inventor and have created PaintPot ( I am using the book App Inventor 2 by David Wolber et al) . Instead of a thin line, I get a fan- like result, as if I am using a 5" paint brush. I have pasted an upload link below, hope it works.
Thank you for this response. In actual fact what I am trying to achieve is the opposite – what should be a straight line is showing as a fan. I at the very early stages of learning App Inventor, and have only keyed in the PaintPot example. This works, but draws the ‘fan’ instead of a line.
Thanks for this. It did not quite work - the additional code gave a option for 'line widt/2' and I don't have this '/2' option. The result is a full screen of colour.
What is bizarre is that I have downloaded this example from the website https://appinventor.mit.edu/explore/sites/all/files/ai2tutorials/paintPot1/PaintPot.apk
and it works perfectly. Looking at the blocks, they look exactly as the ones I have set up. Could this be the version I am using or the physical layout of the blocks - is there an order of execution, as I would have to ensure, as when I am coding in php?
