Draw Text and detect click on it

Screen.drawText - i know, but how to detect click on it ?

You can add this library in to your game and use button function https://microstudio.dev/i/gilles/imgui/

Without a library, you need some way to measure the size of your text. You can use something like:

myText="Hello there"
myWidth=screen.textWidth( myText, 20 )
myHeight=20 // as far as I know, there is no screen.textHeight function
myTextX=0
myTextY=0

draw your text normally in your draw function: screen.drawText(myText,0,0,20,"#fff")

and in your update function:

if mouse.pressed then
  if mouse.x > myTextX-myWidth/2 and mouse.x<myTextX + myWidth/2 and mouse.y>myTextY-myheight/2 and mouse.y<myTextY + myHeight/2 then
    // mouse hit!
  end
end

This calculation assumes that your drawAnchor is set to 0,0, which is the default

Keep in mind that this is totally untested!
