Help with Entity and Net Library

[redcatjack]

Alright, so i'm fairly new to lua and i've been trying to make a basic weed growing addon, but i've ran into a few hitches with the Net Library. Now I may just be retarded and can't see the obvious error(s).
I'm trying to get the message "Growing..." appear of the 3D2D panel when a seed is put into the pot.

If it's not obvious this is the first time i've used the net messages :v:

Your net.Receive cannot be inside of any other function. Place it outside of ENT.Draw and have it maybe set a variable to true. If that variable is true then draw that text and box inside of ENT.Draw.

Also be careful using net messages in a Think hook. If self.IsGrowing is true for more than one time you will be sending net messages way too often. What you should do instead is send a net message when the growing starts to display the text, then send a message when the growing stops to remove the text.

An even better solution would be a NetworkVar.

net.Send() doesn't have a receiver (Missing first argument). Use net.Broadcast() if you want to send a net message to all players.
