What it does "Function Set return value to -1"

I know that "Set return value to Box.UID" will return UID of the created Box

but I don't know What it does on "Function Set return value to -1" here?

okay if remove Box.UID event than what return -1 or 1 does?

Just what it says - your function will return value -1 or 1.

You can use it in conditions or expressions. For example:

if Functions.CheckEnemies=-1 then go to layout "GameOver"

Where CheckEnemies is your function where you count enemies, bosses, and it can return different values.

Another Question

i am trying to move these events into function.

i tries these two ways to achieve but its not working

if i place 3 and 4 out on everytick then when i touch a single sprite then all the sprites are doing action

i have a short question, do you know How can i save 2 number in single cell of array and then retrieve both numbers separately. This could solve my issue.

another question

I have "sprite" 4x4 grid on layout i have another "sprite2" randomly over the grids. without using array How can i pick 2 neighbor "sprite2"

My first try was to do this without array but i didn't find a way to detect 2 neighbor sprites.

But as you said using multi dimensional array. I am going to try it.

Can you give me any tip for comparing 2 neighbor sprites?
