can someone give me the key/security systems for a house i made

what kind do you want?

one like trueheat has on his house

hmm
 

if (playerenters) {
if (!flagset) {setlevel outsidelevelname.graal;
}else {message Welcome;}
}

use scripts such as:

if (strequals(#a,account) {set flagset}

to set the flag for the ppl you want

sorry, if it don't work, im not that good

thanks i will see if it works
