Dectect Press Lightgun Trigger

[Primordial Ooze]

Hi,

 

I am trying to get the screen to flash when the trigger on the lightgun is pressed. I tried the following:

lda INPT5                           	    ; a 0 in bit D4 means the fire button was pressed

bmi SkipCheckFire                     ; if the fire button wasn't pressed then jump to SkipCheckFire

lda #$01

sta FlashState						    ; set gun barrel anaimation to true

lda WHITE

sta COLUBK							   ; set the background color to white

SkipCheckFire

 

However it only works when the fire button is pressed on a joystick controller. Does anyone know how to check if the fire trigger was pressed on a lightgun?

 

Sincerely,
