Whats the easiest way to make a button that when you click it, it will put a box or something on the screen? Sorry if this is a total newbie question or in the wrong forum but I’m learning slowly day by day. Any help would be appreciated.
Thanks,

Hi, fellow newbie) Thats totally basic code for such thing
[lua]local button = display.newRect(100,100,50,50)
local function create_something(event)
if event.phase == “ended” then
local something = display.newCircle(200,200,30)
end
end
button:addEventListener(“touch”, create_something)[/lua] [import]uid: 16142 topic_id: 12341 reply_id: 44948[/import]
Hey fakemode, this type of question should be posted in New Users Start Here - but here is OK too. (Both are appropriate but you’re more likely to get a quick answer in New Users.)
darkconsoles code is spot on - although if you wanted to make it a tad simpler by using tap you could change it slightly to this;
[lua]local button = display.newRect(100,100,50,50)
local function create_something(event)
local something = display.newCircle(200,200,30)
end
button:addEventListener(“tap”, create_something)[/lua]

I love you guys! Is it possible to move the circle freely so when I click the button I can position the circle anywhere I want? If so how would I go about doing that? Also Peach I checked out your site, you rock! Might have to purchase one of your game templates in the future : )
Thanks again,

[lua]local button = display.newRect(100,100,50,50)
local function create_something(event)
if event.phase == “ended” then
local something = display.newCircle(200,200,30)
local function move_something(event)
something.x = event.x
something.y = event.y
end
something:addEventListener(“touch”, move_something)
end
end
button:addEventListener(“touch”, create_something)[/lua]
this works just fine
good luck)
and thats just random funny stuff,try it)
[lua]local physics = require(“physics”)
physics:start()
local button = display.newRect(100,100,50,50)
local bounds = display.newRect(0,0,420,20)
bounds.x = display.contentWidth/2; bounds.y = display.contentHeight
physics.addBody(bounds, “static”, {friction=1,density=1,bounce=1})
local function create_something(event)
if event.phase == “ended” then
local something = display.newCircle(200,200,30)
physics.addBody(something, “dynamic”)
something:applyLinearImpulse(.10)
local function move_something(event)
something.x = event.x
something.y = event.y
end
something:addEventListener(“touch”, move_something)
end
end
button:addEventListener(“touch”, create_something)[/lua] [import]uid: 16142 topic_id: 12341 reply_id: 45077[/import]
looking forward to it, good luck [import]uid: 16142 topic_id: 12341 reply_id: 45105[/import]
You my friend are a saint! Took me a while to get the result I was going for but I finally got it. Is it possible to limit how many circles you can make? Like if make 3 circles the button wont make any more. I Can’t wait to share what I’m creating with you guys.
Thank you so much,
Andrew [import]uid: 72845 topic_id: 12341 reply_id: 45104[/import]
Hey, good stuff!
Yes to your circle question.
Create a variable, say;
[lua]circleCount = 0[/lua]
Then on your button add an if statement, like;
[lua]if cicleCount < 3 then[/lua]
Then when you spawn a circle, add;
[lua]circleCount = circleCount +1[/lua]
Make sense?

Thanks Peach, I tried your code but I’m still getting the same result.
springCount = 0 --YOUR CODE
local button = display.newImage( "springicon.png" )
button.x = display.stageWidth / 1.1
button.y = display.stageHeight / 5.8
button.active = false
local function buttonTouched(e) if e.phase == "began" then
e.target.alpha = .5
end if e.phase == "ended" then
e.target.alpha = 1 print("Replay button was touched.")
end
end
if springCount \< 3 then --YOUR CODE
end
button:addEventListener( "touch", buttonTouched )
local function create\_spring(event)
if event.phase == "ended" then
local spring = display.newImageRect( "Spring.png",50,50)
springCount = springCount +1 --YOUR CODE
spring.x = 600
spring.y = 430
local function move\_spring(event)
spring.x = event.x
spring.y = event.y
end
spring:addEventListener("touch", move\_spring)
physics.addBody( spring, "static", { density=1, friction=0, bounce=1 } )
end
end
button:addEventListener("touch", create\_spring) I’m assuming how I tried implement it is wrong. Sorry I’m such a newb : /

Hehe, it’s OK - we’re all newbies at some stage.
Delete this from line 17;
[lua]if springCount < 3 then --YOUR CODE [/lua]
And change line 32 to this;
[lua] if event.phase == “ended” and sprintCount < 3 then [/lua]
That should fix it
We need to check the springCount immediately before spawning, so you want it there, not way up.

Is this what you mean?
springCount = 0
local button = display.newImage( "springicon.png" )
button.x = display.stageWidth / 1.1
button.y = display.stageHeight / 5.8
button.active = false
local function buttonTouched(e) if e.phase == "began" then
e.target.alpha = .5
end if e.phase == "ended" then
e.target.alpha = 1 print("Replay button was touched.")
end
end
button:addEventListener( "touch", buttonTouched )
local function create\_spring(event)
if event.phase == "ended" and sprintCount \< 3 then
local spring = display.newImageRect( "Spring.png",50,50)
springCount = springCount +1
spring.x = 600
spring.y = 430
local function move\_spring(event)
spring.x = event.x
spring.y = event.y
end
spring:addEventListener("touch", move\_spring)
physics.addBody( spring, "static", { density=1, friction=0, bounce=1 } )
end
end
button:addEventListener("touch", create\_spring) I tried this and when I click the button nothing happens : ( [import]uid: 72845 topic_id: 12341 reply_id: 45481[/import]
Hello
I suggest to you, try to make code cleaner, thats good for you, its easier to navigate that way when code became bigger and complexer
thats the code i wrote and even put some comments in it for learning purposes) good luck, corona is amazing
[lua]_W = display.contentWidth
_H = display.contentHeight
–Our variable that contains number of springs
local springCount = 0
–Our button,that needs to be touched
local button = display.newRect(0,0,50,50)
button.x = _W/2; button.y = _H/2
–Function to move spring, use later in another function
local function move_spring(event)
event.target.x = event.x
event.target.y = event.y
end
–Function to create string at needed x and y; add 1 to springCount per created string
–and add event listener to created string
function create_string()
if springCount < 3 then
local spring = display.newRect(0,0,100,50)
spring.x = 100
spring.y = 100
springCount = springCount + 1
spring:addEventListener(“touch”, move_spring)
elseif springCount == 3 then
print(“stop”) – there you can do anything you want, i just used print for debugging purposes
end
end
–With this function we touch the button and it changes its alpha and use create_string()
local function touch_button(event)
if event.phase == “began” then
print(“began”)
button.alpha = 0.5
elseif event.phase == “ended” then
print(“ended”)
button.alpha = 1
create_string()
end
end
– At last we adding event listener to button and watch magic happens:)

That was very thoughtful of your, darkconsoles - very clean.
fakemode, is that working for you? [import]uid: 52491 topic_id: 12341 reply_id: 45588[/import]
Thank you very much Darkconsoles and Peach, this is exactly what I was trying to achieve thank you thank you thank you : ) [import]uid: 72845 topic_id: 12341 reply_id: 45618[/import]
