Mouse support

[mnml]

Would it be possible to add an API function for polling mouse coords and buttons? Or maybe a memory location one could use to peek() the mouse data?

It's possible and I want to divide input methods, you can use gamepad input only or mouse/touch input only but not both.
I should think how to do it better.
Thanks

Well, for what it's worth, here's how PICO-8 does it. TIC has no stat() function, so the same method wouldn't really work... But maybe it'll give a few ideas?

Here are my thoughts

I'm going to add cart metadata editor where you can define title, author, cover...
And also you will be able to define input method for the game: gamepad or mouse.

So, gamepad state takes 16 bit (8bit+8bit for two players) in memory.
We have 240*136=32640 pixels, it will take 15 bit to address mouse pointer/finger position and 1 bit for button/touch state (pressed/unpressed) to fit the same memory.

+-----------+-----------+
| gamepad 1 | gamepad 2 |
+-----------+-----------+
|   8 bit   |   8 bit   |
+-----------+----+------+
| mouse position |  btn |
+----------------+------+
|     15 bit     | 1bit |
+----------------+------+

Yeah, that seems fair. I was thinking right-click would be nice, but I don't see how it would fit in 16 bits, and it would make dealing with touchscreens difficult... So I'm happy with the 1-button compromise :)

[nesbox]

ok, will implement this "Cartridge metadata editor #37" before

So no mouse+keyboard? I am rather fought between your clean approach and the confort of a very common way of control.

[nesbox]

I thinks yes, I want to all the TIC games be playable on mobile devices where you can't use both gamepad+mouse.

[HomineLudens]

That make sense. I think I can live with it :)

Added mouse support

Can't decide add mouse api function or let people calculate mouse XY by themselves like in example?

-- title:  mouse
-- author: nesbox
-- script: lua
-- input:  mouse

function mouse()
	local b=btn()return(b&0x7fff)%240,(b&0x7fff)//240,b>>15
end

function TIC()

	cls(12)

	local x,y,down=mouse()
	
	spr(1+down,x-16,y-16,-1,4)
	print("x="..x.." y="..y.." btn="..down)
end

[mnml]

API function, I think... That way, it would be consistent with gamepad input, which has btn() and btnp().

I'm a lazy man... mouse is welcome
