I can't seem to put together a variable

[Ranguna259]

So I was trying to do this little love program that saves coordinates to a variable but for some reason it isn't saveing them right.

Basically whenever you press the left mouse button the coordinates of the mouse's current position are saved to pointx pointy[a]

And once there are more than 3 coordinates for both X and Y there is an if code (well, it's a for inside an if) in the love.update(dt) that puts all the coordinates together in one variable called startxy and each coordinate is separated by a comma ",". It does that so that they can be used to draw a line like love.graphics.line(startxy)

This for code is not coded right but I can't seem to see what's wrong with it.

So can somebody please find what's wrong in this code also ignore all the cluster in there, I haven't properly cleaned it yet.

Thanks for reading and please help me on this

You cannot store multiple return values in a single variable unless that variable is a table.

So this:

Code: Select all

a = b, c

effectively just does the same as this:

Code: Select all

a = b

as the second value has nowhere to go.

If you want to add values to a table, you need to put in a few table.insert calls.

Something like this:

Code: Select all

table.insert( startx, pointx[1] )
table.insert( startx, pointy[1] )

should probably help you fix your problems.
