How to correctly use love.mousepressed ?

[ErtYwek]

Hey! I have problem with function love.mousepressed(x,y,mousebutton,istouch). I'm trying to make a simple button library and as you can see below I've made something already. But unfortunately, I stuck on trying to let buttons change the color after mouse click until the mouse button is not released. Before clicking button already change color (like a mouseover).

This is how i implement my buttons:

Code: Select all

ial_butt("-","rect","5","Help",topbar_txt_size,186,0,n,n,
      n,n,n,n,n,n,n,n)--TBM tree5

Full* code of library:

Code: Select all

ialdatatable={  }--[[ ["ial_butt_gC1"]=0, ["somedata"]=0 ]]
ialtabulator={  }
--ial_butt_run=0

do

* below there is a function providing colors but it works as I want and I'm sure it doesn't cause any problems.
Tell me if you need .lua files to help me.
/EDIT Thank you, but I explored Uare scripts and I understand completely nothing from them, they are too professional for me. Even more creepy is that there is no love.mousepressed nor mousereleased in his library so how it can work?

It might help you to take a look at Uare. One of the buttons on the button sample there has exactly the behavior you want, and the whole thing is short enough that you can likely wrap your mind around it quickly and see what you're doing differently.
