Arrays and Tables - johnno56 - 11-24-2024
I am familiar with arrays and gradually getting my head around tables... My question may be lame but I need to know... How does one determine whether to use an array or a table?

HI Johnno,
I have never felt the need to distinguish between the two, but perhaps the explanation of Tables in the document for migrating from N6 will help:

All the best - Kevin.

Cool. Thank you for the PDF. Hopefully it will make things a lot clearer...

It doesn't really matter what you use
I think tables (arrays are just a special case) make things look clearer. Let's say you want to have an array with 100 enemies, where each enemy has an image, a position (x, y) and speed (x, y):Code:
anImage = loadimage("dummy.png")
' using numeric indexes.
enemies = fill([0, 0, 0, 0, 0], 100)
' set image, position and speed of enemy 53.
enemies[53][0] = anImage
enemies[53][1] = 91
enemies[53][2] = 132
enemies[53][3] = 1
enemies[53][4] = -1
' using string keys.
enemies = fill([img: 0, x: 0, y: 0, dx: 0, dy: 0], 100)
enemies[53].img = anImage
enemies[53].x = 91
enemies[53].y = 132
enemies[53].dx = 1
enemies[53].dy = -1RE: Arrays and Tables - johnno56 - 11-27-2024
Thanks Marcus. Much appreciated.
