My question is very simple : how call touch function from class in main ? Like
function draw()
br:draw()
end
but this dont work in touch func
There is snippet of my code :
Main class
function touched(t)
br:touched()
end
Bricks class
function Bricks:touched(touch)
-- Codea does not automatically call this method
if touch.state == BEGAN then
if self.vec:dist(vec2(CurrentTouch.x,CurrentTouch.y)) <= 20 then
table.insert(cells,vec2(300,100))
correcttap = correcttap + 1
if correcttap > 3 then
correcttap = 0
end
end
end
end
Well after reading your code I saw a few mistakes you’ve made…
The draw thing in the beginning is fine though.
When you tried to call the Bricks touch function from Main, you simply forgot to give the touch to the Bricks class touch function (codea also does not automatically do that)
I assume, you definded self.vec as a position on the screen in the init function of your Bricks class, so that’s fine. But later on in the same line you wrote vec2(CurrentTouch.x, CurrentTouch.y), which should be avoided when using the touched() function, because the argument (touch) parsed in the touched(…) function from your main class already contains every needed information about your specific touches on the screen.
You did not make this mistake one line above (when you wrote touch.state). Better do so over there too (meaning vec2(touch.x, touch.y), because CurrentTouch on,y contains information about your last touch on the display, which may differ from the one processed by the touched function at this position.
Also maybe check out touch.tapCount, it may help you further on
Thank you a lot for your response! About touch.x and touch.y : i know that) that line
was copied from draw function, there touch.x and touch.y dont work
if touch.state == BEGAN then
if self.vec:dist(vec2(CurrentTouch.x,CurrentTouch.y)) <= 20 then
table.insert(cells,vec2(300,100))
correcttap = correcttap + 1
if correcttap > 3 then
correcttap = 0
end
end
end
