Like most here I’m new, excited and going into a whole new world with a very little knowledge and hope that you pro’s out there can throw me a little wisdom to help me past my first stumbling block.
My Goal:
To create a very simple quiz for kids.
Currently I have 4 questions i.e. How many apples? How many oranges?
I have 9 numbers they can drag each number around the screen
I’m trying to make it so when they drag the correct answer to the correct question it triggers an image to show the kids they have got it right.
I’m not sure if on-collision is the right way to go and I’ve not had any luck getting that working yet! I don’t need physics physics on the game just touch & drag into the right spot on the screen.
Later i’ll try to make this add to a score and when all questions are correct move to the next set of questions BUT one baby step at a time for now
Thanks guys, hope you can help

Well I am about to write a simple hitTest function for detecting when images are overlapping; I need it for my game and I’ll post that function on the forum.
Although I need to be checking the actual boundaries of the images, for the situation you described it should be fine to simply detect in a circle around each spot. [import]uid: 12108 topic_id: 5230 reply_id: 17417[/import]
I’ve taken a look at the link, had a quick play but not having much luck at the moment, to be honest i’m not 100% sure how to get that working?
Seeing a working sample of something would help me understand better, if anyone knows of anything on code exchange or in one of the sample files can you let me know please.
Thanks again jhocking! [import]uid: 13654 topic_id: 5230 reply_id: 17461[/import]
local number = display.newImage("number.png")
local answer = display.newImage("answer.png")
local star = nil
number.addEventListener("touch", number)
function number:touch(event)
if event.phase == "moved"
number.x = event.x
number.y = event.y
elseif event.phase == "ended"
if distanceBetween(number, answer) \< 30 then
star = display.newImage("star.png")
end
end
end
I’m at work so I can’t test if this actually works; think of this as pseudo-code giving you the general concept. [import]uid: 12108 topic_id: 5230 reply_id: 17578[/import]
function hitTestObjects(obj1, obj2)
local left = obj1.contentBounds.xMin \<= obj2.contentBounds.xMin and obj1.contentBounds.xMax \>= obj2.contentBounds.xMin
local right = obj1.contentBounds.xMin \>= obj2.contentBounds.xMin and obj1.contentBounds.xMin \<= obj2.contentBounds.xMax
local up = obj1.contentBounds.yMin \<= obj2.contentBounds.yMin and obj1.contentBounds.yMax \>= obj2.contentBounds.yMin
local down = obj1.contentBounds.yMin \>= obj2.contentBounds.yMin and obj1.contentBounds.yMin \<= obj2.contentBounds.yMax
return (left or right) and (up or down)
end
You call this function with two images. It returns true if the images are overlapping, and false if they aren’t. You can use this instead of the distanceBetween check in the code above; either way should work.
Your a star, thanks so much for your help with that, I now have it working with 4 questions, it can detect correct & incorrect answers and show congratulations box if all four are answers are correct.
Couldn’t have done it without your help!!! [import]uid: 13654 topic_id: 5230 reply_id: 17779[/import]
