XOBJ Control

The XOBJ control listener is the standard way to accept control events for the entire linkset, using control. Most often added to a project #ROOT script.

Example setup:

Global scope:

float pressStart;
float lastclick;

default:

    control(key id, integer level, integer edge){
        if(level&edge){ // Pressed
            pressStart = llGetTime();
            raiseEvent(evt$BUTTON_PRESS, (string)(level&edge));
            if(llGetTime()-lastclick < .5){
                raiseEvent(evt$BUTTON_DOUBLE_PRESS, (string)(level&edge&lcb));
                lcb = 0;
            }else{
                lastclick = llGetTime();
                lcb = (level&edge);
            }
            
            integer i;
            for(i=0; i<32; i++){
                integer pow = llCeil(llPow(2,i));
                if(level&edge&pow)multiTimer(["H_"+(string)pow, 0, 1, TRUE]);
            }
        }
        
        if(~level&edge){
            raiseEvent(evt$BUTTON_RELEASE, llList2Json(JSON_ARRAY, [(~level&edge),(llGetTime()-pressStart)]));
            integer i;
            for(i=0; i<32; i++){
                integer pow = llCeil(llPow(2,i));
                if(~level&edge&pow)multiTimer(["H_"+(string)pow]);
            }
        } 
    }

This example will raise the following events:

Event	Arguments	Description
evt$BUTTON_PRESS	int buttons	Raised when you press a key.
evt$BUTTON_DOUBLE_PRESS	int buttons	Raised when you double-tap a key.
evt$BUTTON_RELEASE	int buttons, float duration	Raised when you release a key.

Don't forget to add llRequestPermissions(llGetOwner(), PERMISSION_TAKE_CONTROLS); and take controls in the run_time_permissions_event llTakeControls(CONTROL_UP|CONTROL_DOWN|CONTROL_ML_LBUTTON, TRUE, FALSE);
