a "kill wall" for evocity_v2d

i know there is some scripts out there for a “cave” block and so it blocks the whole area of the tunnel and those two suburb houses but i was wondering if there was some one who might be able to help me out with a script to make a kill wall that would be ((invisible (optional) but make it so it if some one goes past the lake it would either kill them or teleport them to the main town aka nexus.

if some one either has one or can perhaps help me with a basic script of some sort in order to accomplish this task it will be very much appreciated. i ask only because im not very good at lua at all.

as i said any help at all would be very much appreciated

also im willing to pay 5-10$ for a decent one on paypal
