Game Maker Xin 1.1 extension documentation

by blobeee

I made this reference sheet since I couldn't find any info about this ancient Game Maker extension anywhere on the internet. Tested in Game Maker 8.0 Pro on Steam Deck via Proton Experimental 2024-10-23.

Quick start

Diagram of an Xbox 360 controller with example code snippets for accessing each controller input.

Port numbers are Zero indexed! i.e. Player 1 is id 0, Player 4 is id 3.

Table of functions

Xin provides 8 functions for accessing and managing XInput devices, such as an Xbox controller or virtually (haha) any controller via Steam Input.

FunctionParametersOutputexample

xin_check(index,button)

int index = port number
int button = button id
See xin_check() button values

 Returns bool (0 = not pressed, 1 = pressed) draw_text(x,y,xin_check(1,xb_a)) //display whether player 2 is pressing the A button

xin_check_pressed(index,button)

int index = port number
int button = button id
See xin_check() button values

 Returns bool (0 = not pressed, 1 = pressed), but only stays true until next room step. draw_text(x,y,xin_check(1,xb_b)) //display whether player 2 just pressed the B button

xin_check_released(index,button)

int index = port number
int button = button id
See xin_check() button values

 Returns bool (0 = still pressed, 1 = released), but only stays true until next room step. draw_text(x,y,xin_check_released(1,xb_y)) //display whether just let go of the Y button

xin_get_input(index)

int index = port number

 Returns int value showing button id xin_get_input(0) //check which button Player 1 is currently pressing.

xin_get_input_bitmask(index)

int index = port number

 Returns int bitmask respresenting button combination xin_get_input_bitmask(0) //check which buttons Player 1 is currently pressing.

xin_get_state(index,button axis)

int index = port number
int button axis = axis id
See xin_get_state() analogue axes

 Returns bool (0 = not pressed, 1 = pressed) draw_text(x,y,xin_get_state(1,xb_rightTrigger) //display how far Player 2 is pulling their Right Trigger

xin_set_rumble(index,left,right)

int index = port number
float left: left motor
float right: right motor
Max precision is 2dp / 3sf, so smallest rumble value is 0.01

Sets rumble strength of motors on each side of controller at port index

 xin_set_rumble(3,0.01,1) //set Player 4's rumble to minimum strength on left and maximum strength on right

xin_update(index)

int index = port number

Port numbers are Zero indexed! i.e. Player 1 is id 0, Player 4 is id 3.

 bool (0 = disconnected, 1 = connected)

Returns Boolean connection status of the gamepad connected to the specified port.

 switch(xin_update(0)) //player 1's controller
{case 0: plug = "unplugged";break;
case 1: plug = "connected"}
draw_text(x,y,plug)
