Finding a String Size

Hello,

You know there is a

string.len

which returns how many characters in the string.

I want something similar to that. That will return the size of the string in x position.

Like,

1
2
3

str = "Hey."

print(string.leng(str))

This will show me 4. But the thing is, the dot takes less space than other characters. Just example, let's say "." takes 1 pixel, "H" 4, "e" 3 and "y" 3. But I'll never have an idea what exactly space do they take.

How to get these?

Impossible

You have to write own wrapper for that.

Yes, it is possible. You just have to write your own wrapper.

Just call this function on your string and you're golden.

Now calling that function is a little bit more tricky within lua, but not impossible.

Masea: Text size will depend on font used. Unless it's a standalone mod it will be unrealiable.

use your own image font instead of the game fonts, then write your own wrapper
