Trying to code two player chess, but can't find the
commands for a Second Joystick anywhere in the documentation.
My first Joystic setup looks like this and works perfectly:

+ Code Snippet

SetJoystickScreenPosition ( 100, GetVirtualHeight() - 100, 90 )
if(GetVirtualJoystickExists(1))
    SetVirtualJoystickVisible(1,1)
    SetButtonScreenPosition(1,GetVirtualWidth() - 50, 100, 80)
    SetVirtualButtonSize(1,100,50)
    SetVirtualButtonText(1,"Fire")
endif


yAxisMovement# = GetJoystickY()
	 xAxisMovement# = GetJoystickX() 
    if( abs(yAxisMovement#) > 0.1)
    		spriteX# = GetSpriteX(board_WhiteHandOpen)
      	spriteY# = GetSpriteY(board_WhiteHandOpen)
        	SetSpritePosition(board_WhiteHandOpen,spriteX#,spriteY# + 20* yAxisMovement#)
       	endif
       
   
        if( abs(xAxisMovement#) > 0.1)
        spriteX# = GetSpriteX(board_WhiteHandOpen)
        spriteY# = GetSpriteY(board_WhiteHandOpen)
        SetSpritePosition(board_WhiteHandOpen,spriteX#+ 20* xAxisMovement#, spriteY#)
    endif
    
    if(GetButtonPressed(1))
        print("BOOM")
    endif

1) How do I let the computer know it is looking for 2 joysticks?
2) What are the commands for recognising a second Joystick?
3) Are there own commands for each seperate joystick or do I just call for (1) or (2)...?

Our first game will soon be up on Steam, if you want to check it out, it's called Cubes of Death and realease will be 18th of October 2021.

Best Regards

That's Great news some one submitting game on steam. It will very helpful for community in near future

. Anyways You looking for Virtual Joystick ? or Physical Joystick ?

If Physical Joysticks then use [ integer=GetRawJoystickExists ( id ) ] id is an integer value (1 to 4) giving the ID to be tested. ( means max 4 joysticks you can connect )
The function will return 1 if the specified ID has been assigned to a physical joystick,otherwise zero is returned.

So, you can create a second virtual joystick yourself by calling AddVirtualJoystick(index, x, y, size). Index must be in the range from 1-4. Later you can access this information by calling GetVirtualJoystickY(index) for example.

+ Code Snippet

global multiplayer as integer = 1
global joy_p1 as integer = 1
global joy_p2 as integer = 2

SetupJoy()

do
if multiplayer = 1
InputMp()
else
InputSp()
endif

Sync()
loop

function InputMp()
if GetVirtualJoystickY(p1_joy) 
...do something
if GetVirtualJoystickY(p2_joy) 
...do something
endfunction

function InputSp()
if GetVirtualJoystickY(p1_joy) 
...do something
endfunction

function SetupJoy()
if multiplayer = 1
AddVirtualJoystick(joy_p1,10,10,20)
AddVirtualJoystick(joy_p2,100,10,20)
else
AddVirtualJoystick(joy_p1,10,10,20)
endif
endfunction

Something along those lines.

prinsallan,

you're mixing the AppGameKit "Guaranteed" Joystick (which will look for a physical joystick and create a Virtual Joystick if none found and/or allow WASD (simulated) "joystick" controls if a physical keyboard is detected) with Virtual Joysticks . Note:

Quote: "Definition
float GetJoystickX() "

...isn't asking for a Joystick ID where it assumes the joystick. in short, there is no 2nd AppGameKit Joystick.

so, as hosch says, Virtual Joysticks and Virtual buttons are what you appear to be looking for (which uses Virtual Joystick IDs for reference/provide for multiple joystick controls). and, if you want to provide for physical joysticks, as well, you'll need to check for those manually, then create the virtual sticks/buttons as necessary.

aka, note the Input separate headers:

Joystick, Button

vs

Virtual Joystick, Virtual Button

then, the Input Raw Joysticks which are more-robust commands for physical joysticks (only).
