Returns 1 if the specified node, group, or bundle exists. Usage opexist(op_name) Examples echo `opexist("../box1")` echo `opexist("/obj/@mygroup")` echo `opexist("@mybundle")`
But I can't seem to get it to work properly. Whenever I add a @ symbol into my op_name path, it turns green and always returns 0.
I've tried to specify the full path and I tried using backticks and several other methods, but it doesn't seem to detect if my groups exist or not.
Does anyone know how to use this expression, or if another expression exists that does the same thing.
