help! shapes output and array issues!

[japgoth]

Hi everyone, just need a bit of help here as ive been staring at this code for 4 days and not making much headway.
Also its apperantly a classic *drumrolls* area of shapes! with x,y location :D

Basicly in a nutshell its going to be an array of 20 (at the moment set at 2) of class shapes with subclass exented ( circle, square, retcangle and polygon)
with X,Y location. Also stuck on polygons :(

At the moment i think that i have made a uttermistake and now damaged the code. As now circle seems to provide one output while the square option puts out three output results!

//remember to change the area back to 20!
// also need to put the shapes into an array.

Right the arrays and else-if have been fixed braces issue {...} now having issue with location giving numbers out as 26c623af for example, and I don't know how to start the polygon

You are passing the object centre as part of the dialog string.
You need to pass centre.x + ", " + centre.y
