[Resolved] Using function in correspondence with many objects

Solar2D General Questions/Discussion

Hi all,

I was wondering if it would be possible to use one function on multiple objects in order to check x coordinates and then change them.

Thanks,
Chris

Yes. Do you want to check just one object at a time or be able to check a number of items at the same time? [import]uid: 74503 topic_id: 28163 reply_id: 113764[/import]

Hi,

Thanks for the response, and I would like to be able to check multiple objects at the same time.

It’s perfectly possible. The best way to do it would be to add all the objects that you want to check into a table (or common display group) and use a loop to iterate through the table something like this:

[lua]-- Create table and add display objects

local tableOfObjects = {}

tableOfObjects[1] = display.newRect(0, 0, 150, 150)
tableOfObjects[1].x = 75
tableOfObjects[1].y = 200

tableOfObjects[2] = display.newRect(0, 0, 150, 150)
tableOfObjects[2].x = 150
tableOfObjects[2].y = 400

tableOfObjects[3] = display.newRect(0, 0, 150, 150)
tableOfObjects[3].x = 225
tableOfObjects[3].y = 600

– Function to iterate through them all in sequence

local function printAllX()

for i = 1, #tableOfObjects do

– Access the x property of all display objects in the table
– Simple print example here - add your own code to move the x positions

print( tableOfObjects[i].x )

end

end

printAllX()[/lua]

That should get you started. Of course, you could use a similar loop to set up the display objects too, but for simplicity in this example I haven’t.
