Hi, all,

I am looking for suggestions on how to approach using a joystick like a mouse.
(joystick moves a pointer around the screen to select things)

I've tried a method where the 'harder' you push the joystick in a direction, the faster the cursor moves.
I've also found some strange behavior on the diagonals (less response in both directions)

So what have you tried? And better yet , what *works* ?

Thanks,
Bob

The last joystick I had used the MIDI interface!
Maybe I should buy one and have a play.

You could do something like...

+ Code Snippet

SetRawMousePosition( GetPointerX() + GetJoystickX(), GetPointerY() + GetJoystickY() )

This WILL NOT work on touch enabled devices, as you can't move the pointer location. (Without touching the screen)

You can however, create your own mouse pointer variables, and use the above to set it's positions via the joystick/pad, and refer to those, rather than AGK's pointer/mouse commands.

hmmm... that is actually quite interesting,
although "position the actual mouse pointer" was not what I had in mind.

i'm just looking for a proper implementation of using a gamepad/joystick on a PC to move a "cursor"...

interesting though, I will mess with that

The real problem is making the cursor move fast enough when the player wants it to go clear across the screen , vs. allowing fine control.

Using (and modifying) something mobiius suggestion, I've done this:

+ Code Snippet


x#=getrawjoystickx(1)
y#=getrawjoysticky(1)
print(x#)
print(y#)

magx=25
magy=25
 if abs(x#)<0.51 then magx=16
 if abs(y#)<0.51 then magy=16

 x=getpointerx()+(x#*magx)
 y=getpointery()+(y#*magy)
setrawmouseposition(x,y)

basically, if you are not pushing very hard on the stick, it uses a smaller multiplier to movement ("magnitude").

It works fairly well, but could probably be refined over time... and it's annoyingly hard to close...

If you take the joystick value (0 - 1.0) and convert it to a value between 90 and 180 (90 + (90 * joyStickVal)) you can then use SIN to make the joystick value respond better.
i.e make the range in the bottom end of the movement more accurate, and at the top end it will start to react slower to movement as the speed increases.

Stardew Valley (great new indigame) does straight joystick angle to movement speed. The more you tilt the faster the cursor moves. It's works great for that game, but you don't need to use it often when playing with a controller so I don't know if it's optimal for your game.

BatVink,
that seems interesting, but also a little confusing to me.
I will play around with it.

regarding "stardew valley", I watched the release of that one. I swear they must have been paying to review the game, it had >1000 steam reviews in its first HOUR.

thanks everyone.

Here is some code to explain it. It prints the joystick input 0 - 1 and Joystick Output, also 0 - 1
BUT the output has been converted so that initial movements are finer than faster movements the other extreme

+ Code Snippet

SetScreenResolution(1024,768)
SetWindowSize(1024,768,0)
SetVirtualResolution(1024,768)


SetPrintSize(16)
c1 = MakeColor(255,128,128)

global accel as float[20,3]

	for i = 0 to 20
		
		// get a value from 0 to 1 (emulating joystick)
		accel[i,1] = (i * 5) / 100.0
		
		//Convert to a value from 90 to 180
		accel[i,2] = (90 + (accel[i,1] * 90))
		
		//Now convert to a value between 0 and 1
		accel[i,3] = 1 - sin(accel[i,2])

	next i
		
do
	for i = 0 to 20		
		print("Joystick = " + str(accel[i,1],3) + chr(9) + " Angle = " + str(accel[i,2],3) + chr(9) + " Acceleration = " + str(accel[i,3],3))
		if i > 0
			startX# = (i-1) * (GetVirtualWidth() / 20)
			startY# = (getVirtualHeight() - 50) - (accel[i-1,3] * 500)
			endX# = (i) * (GetVirtualWidth() / 20)
			endY# = (getVirtualHeight() - 50) - (accel[i,3] * 500)
			DrawLine(startX#, startY#, endX#, endY#, c1, c1) 
		endif
	next i

	sync()
loop

Talked to a friend who had already played during early access. So that game was popular even before it released. And when it did, every one put in a review. It's a really good game too. Played it a ton when I bought it, was sick and home from work too so had plenty of time.

@BatVink:
great idea, with the SIN() . I tried it, but whether I pushed right or left, it all went the same way. (number was always positive).
so here is how I implemented it. it is much sloppier than yours, but it is my first experiment with it, and it works.

+ Code Snippet

 rdx#=getrawjoystickx(1)
   rdy#=getrawjoysticky(1)
   dx#=90.0+(rdx#*90.0)
   dy#=90.0+(rdy#*90.0)
   if rdx#<0.0
    rdx#=-1.0
   else
    rdx#=1.0
   endif
   if rdy#<0.0
    rdy#=-1.0
   else
    rdy#=1.0
   endif
print(dx#)
   dx#=1.0-sin(dx#)
   dy#=1.0-sin(dy#)
print(dx#)
    testx=testx+dx#*15*rdx#
    testy=testy+dy#*15*rdy#

   setspriteposition(1999,testx,testy)
