I and Senkasui already made that for Gaia long time ago,we basically used ganis & keydown.
NPC Code:
if(created){
timeout=0.05;
}
if(timeout){
if(keydown2(17,true)){
if(keydown2(keycode(1),true)){
setani dead,; //Put the new emoticon gani here
}
}
timeout=0.05;
}
If you press ctrl+1,it will active the gani dead,just replace that gani by the emoticon gani.
