Some models have t.mdl instead of T.mdl, this can be a problem on OS with case-sensitive filesystem (like Linux) rehlds/ReHLDS@6715402.

This is not the way how it should be checked, you need to check if model really needs it rehlds/ReHLDS@9080b9b#diff-462e3f794ed90c12c86f5d8d5b725c4aR5405.

@WPMGPRoSToTeMa Which I assume can't be done with a stock?

@OciXCrom it can be done through the reading of model file.

id = precache_generic(model);

static const extension[] = "T.mdl";

@justgo97 It doesn't need to be defined more than once. It acts like a global variable with a local scope.

static is bad here because its lifetime (or "extent") is the entire run of the program while these stock will be only used in one forward.

static is fully OK for local array/string constants. There is no other option:

  1. new isn't appropriate here because it does copying on each function call.
  2. Global constant is bad because we use this constant only in this function, so there is no reason for it to be global.

yeah but this string constant is pretty small in size and in its use having it static means it will stay in memory all the time while its only needed at the 1-2 seconds of map start for plugin_precache forward ?

@justgo97 no, new = data + stack, static = data.

@WPMGPRoSToTeMa I mean in overall which is better for memory ?

public plugin_init()
{
    func1()

    func2()
}

public func1()
{
    new const Block1[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
    new const Block2[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
    new const Block3[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
    new const Block4[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
    new const Block5[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
    new const Block6[] = "I_M_GOING_TO_STAY_IN_MEMORY_JUST_FOR_THIS_FUNC"
}

public func2()
{
    static const Block1[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
    static const Block2[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
    static const Block3[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
    static const Block4[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
    static const Block5[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
    static const Block6[] = "I_M_GOING_TO_STAY_IN_MEMORY_FOR_EVER"
}

@justgo97 if consider only permanent memory, then they are both the same.

@WPMGPRoSToTeMa so for non-permanent memory new is better, which is an advantage for new over static ?

It doesn't matter, you shouldn't spend time deciding that while coding.

charsmax isn't named good for this case, it would be better to have something like const_strlen.

return precache_model(model);
