I’m going to use these three as an example. Basically if you place your character screen center and then check what their coordinates are, you will see spot 1.280 160 0
I have a post on spot directing:

And an in depth video explaining the three values on my channel.
spot 1.280 160 0
spot % X Y
The first number (%) is height (1.280 which is default)
The second number (160) is left, right direction of character. Lower numbers on the left, higher numbers on the right. Think of it like a graph.
The third number (0) is up, down of the character. Higher numbers up, lower numbers down.
So 1.280 50 0 = screen left (50)
1.280 160 0 = screen center (160)
1.280 270 0 = screen right (270)
You can also view the Episode Guides chart that contains the spot directing values of the zones (it has the X-axis-horixontal and the Y axis-vertical).
