The debugger is one of the most important tool but so many (Unity) beginner skip it and then they don't know how to fix even simple errors. I will send people here to watch the video so they can finally learn to debug :D

I also have Unity setup so the background color gets dark if i'm running it. It helps me to not make changes when running. Saves me time from having to do things over again that I want to be permanent.

Thank you very much for your videos. They have helped me a lot and i´m getting one of my childhood dreams. Thanks.

Unfortunately i´m a beginner to visual studio and Unity. Do you know a youtuber who have tutorials for beginners? Thanks.

About this video, i have the second error and my code is:


void HandleMoveSelection()
{
if
{
if (currentMove < - 1)
++currentMove;
}
else if
{
if (currentMove > 0)
--currentMove;
}
else if
{
if(currentMove < - 1)
currentMove += 2;
}
else if
{
if (currentMove > 1)
currentMove -= 2;
}

dialogBox.UpdateMoveSelection(currentMove,
}

The particular thing is that my characters have 8 moves or less not 4 or less, like this:

Move 1 Move 2 Move 3 Move 4
Move 5 Move 5 Move 7 Move 8

What do i have to do to fix it?

Thanks very much for all.

Finding the errors is not difficult, the difficult part is knowing what to put in their place...
