Question

This is the code (corona SDK btw), it is calling a physicsdata (unimportant).

 r = math.random(1,5)
local scaleFactor = 1.0
local physicsData = (require "retro").physicsData(scaleFactor)
physics.addBody( enemy, physicsData:get(r) )

The r in

 physicsData:get(r) )

has to be inside speech marks to work (I tested).

how can the r variable be string-ilised? ( 😀 )

Answer 1

If you need a string,

tostring(r)

For example,

physics.addBody( enemy, physicsData:get(tostring(r)) )

If you really need quotes in the string (I doubt you do):

physics.addBody( enemy, physicsData:get('"' .. tostring(r) .. '"') )
