How would I get my turing program to stop flashing? I have used View.Set ("offscreenonly") as well as View.Update and View.UpdateArea, but still it keeps flashing, what can I do? |

You're using View.UpdateArea more than once. You should only use it more than once in the same loop if there's a good reason for it. In this case, there is not. |

Did you not understand my post from the other thread you made? I opened your code, and on the second line you still have
Which should be
Note that there isn't a space in the correct version. As for the sun and moon, your code:
Is of the form:
-Delay 100 milliseconds -Draw a black oval over the sun on the off-screen buffer, effectively removing it -Move the sun coordinate down 10 pixels -Draw the off-screen buffer to the screen If you rearranged those, it would make more sense. This pattern is found throughout your code, and a simple re-ordering fixes pretty much all of your flickering problems (at least anything I saw). Just remember: nothing gets drawn to the screen until View.Update() or View.UpdateArea() are called. |
