Element properties

    Are element properties using bit masking for the flags?

    They do, and the Lua versions TPT supports don't have bitwise operators, but unless you're modifying existing flagsets, you can just use the addition operator '+' to combine flags, as long as you never use the same flag twice.

    doesn't tpt have the lua 'bit' library which has bitwise operators?
  • LBPHacker     9th Feb 2021 Developer 0 Permalink
    It does, but it's overkill for what I described, which is the most common use case.

    Well I managed to find a way to check if a flag is set or not. The bit libarary is in fact what I needed.


    bit.band(tpt.el.stne.properties,elements.TYPE_PART) == elements.TYPE_PART

    Be more specific next time then :P Also, try to avoid using tpt.* stuff, use elem.property(elem.DEFAULT_PT_STNE, "Properties") instead of tpt.el.stne.properties.

    Is it still bad to use tpt.* in console? I know it shouldn't be done in production code. Also I never noticed that elem can be used instead of elements.

    It doesn't really matter, but everyone has (should have) more experience with the new APIs and can provide help better if you just use those. The tpt.* API is only (supposed to be) provided for compatibility (except we still add stuff to it like setdrawcap, which we really shouldn't).
