Removing object using ID

[lazerguy 10]

So, in editor oi know i need to use the code "(getpos this nearestobject 314) setdamage 1" to remove an object but i dont know where to input it. Is it just in a trigger placed above the object in the on ACT. text box?

Save your mission as User mission, goto missionfolder, create new text file, save as init.sqf, put in the above code, test mission in editor.
