I found myself in a tricky situation yesterday. I had used my spiky ball tech to dodge a boss but had lost almost all my health, literally only a sliver of it left. I was relatively safe where I was perched but badly needed to apply a salve or medkit. I knew if I turned off the sphere to apply a healing item I would immediately die and have to start the fight from the beginning again. Since there's no way to use items while in the sphere form I had to resort to /admin. It was either that or throw my mouse at the monitor. So, is it possible to mod in the use of items while using the sphere tech? I've had a look at the .tech files - I can adjust things like speed and make the spiky ball able to jump but I can't see anything in there to allow the use of items such as salves etc. Perhaps this is locked off in the code rather than configurable...?
You have to edit the Lua script for the sphere tech you are using. There is an option that sets the usage of tools to false. Just change that to true.
