I'm new to this forum and I didn't find anything else than this (link removed) in order to help me in my quest.
You move the GREEN DOT by touching the BLACK SURFACE.
It means, the dot follows the finger.
When touching the black surface, the touch position is return in order to set an angle for the bullet movement of the green dot.
There is button on the left that the player will touch sometimes. there is no need to let the finger on the buttons but it can happens (if the player doesn't pull his finger up).
And that's the problem :
If a touch is done and hold before a touch on the black surface, the returned position is the wrong one (outside of the black surface).
I was testing with the touch manual to deal with it.
But I'm totaly lost with the TouchCount / ID / Index expression.
I need to always return a position within the black surface.
I hope someone can answer me !
Sorry if I made any mistake, I'm a french guy who really wants to learn Construct 2!
