i have invedit but my computer keeps saying its a Malware program, but its really helpful. So i recommend downloading it :)
Yes it is.
Anything you want.
I don't think you can I'm not sure but I'm pretty sure they would have a download link to an updated INVedit
Search "Terraria invedit" on youtube.
Almost certainly no.
Invedit. An Inventory editor.
Yes. you can use INVEdit.
open up Invedit, select "open from" and chose the world you want to invedit, and search for items you want and drag them into your inventory (the boxes). then click save to world # (whatever you want)
You can always use an inventory editor. I use INVedit
InvEdit can sometimes work on a Mac using Mono (See links below). Once installed you would enter: mono invedit.exe into the Mac's Terminal application found in the Utilities folder within the Applications folder.
