I'm struggling with how to check if a displayGroup exists inside another displayGroup.
In my work-in-progress I have envelopes moving along a conveyor belt. I'd like it so that the user can then touch and drag a new conveyor belt for the envelope to move on (similar to the line drawing examples just that in this case I'm using a an image inside a masked display group).
I've worked out how to insert displayGroups into a table (note: the following doesn't include masking):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | local mainGroup = {} for i=1, 3 do mainGroup[i] = display.newGroup() mainGroup[i].name = ("group"..i) display.newImage(mainGroup[i], "conveyor.png") end for i=1, #mainGroup do local tester = mainGroup[i] if (tester.name == "group1") then print "Exists" else print "Nope" end end |
