Lua Reading text from a writeable/readable item in lua

[iclutcha]

Where is the text that is written in a letter (2597), for example, stored?

Depends on version.

Maybe:
getItemText(item.uid)
or
getItemAttribute(item.uid, "text")

 

[iclutcha]

No luck, tried both and a couple that were included in the LUA_FUNCTIONS file. (I'm using TFS v0.2.14 for 9.60/9.61)

if getItemText(item.uid) and getItemText(item.uid) ~= "" then
	print(getItemText(item.uid))
end

Error?

I just looked at source and there seems to be no function like this.

So add this function:
[cpp]int32_t LuaScriptInterface::luaGetItemText(lua_State* L)
{
//getItemText(uid)
uint32_t uid = popNumber(L);

ScriptEnvironment* env = getScriptEnv();

const Item* item = env->getItemByUID(uid);
if(item)
lua_pushstring(L, item->getText().c_str());
else
{
reportErrorFunc(getErrorDesc(LUA_ERROR_ITEM_NOT_FOUND));
lua_pushboolean(L, false);
}
return 1;
}[/cpp]

Also, dont forget to register the function in luascript.cpp and declare it in luascript.h.

As far as i know, functions like 'getItemText', 'getItemName', 'getItemDescription', etc.. are added in libs.
Personally, i prefer to use 'getItemAttribute(uid, "attr")'

I did not find any matching function in global.lua nor in sources, also there is no getItemAttribute either.
Correct me if I am wrong.
