How do I set item's "tool_capabilities" from item meta?

[davidthecreator]

When I tried to write

Code: Select all

itemstack:get_meta():set_string("tool_capabilities", "{}")

It does seem to work and completely remove all tool capabilities from the item...
But when I actually write some sort of capability I want to edit, it dosen't work...
For example, if I try to change the full_punch_interval:

Code: Select all

itemstack:get_meta():set_string("tool_capabilities", "{full_punch_interval=1.0}")

It dosen't work... And says: "Missing '}' or object member name" ...

So how do I make it work?

From what I know, the item meta string expects a string in the JSON format. You can generate this by using

Code: Select all

local meta = itemstack:get_meta()
meta:set_string("tool_capabilities", minetest.json_encode({
        full_punch_interval=1.0
}))

I'm not sure, however.

Didn't work... But thanks...

You should use the set_tool_capabilities(tool_capabilities) method

Code: Select all

local caps = stack:get_tool_capabilities()
stack:get_meta():set_tool_capabilities(caps)

Also remember that stacks are a copy, not a reference. You need to update the slot in the inventory

Thanks, it worked.
