There are shouldn't be any magic numbers in code

[bogdasar1985]

Magic number is a numerical constant in the code, the purpose of which is unclear.
Example from Platform.cpp:

platformSpeed = speed * 0.00125;

What does 0.00125 mean?
In most cases, this is corrected by adding #define directive with this number in header file.
In that case it should be like:

// Platform.h
#define MEANING_OF_MAGIC_NUMBER 0.00125

The similar sutuation with AllHitboxInf::animationProcess.
For example, in this function:

// Platform.cpp : line 45
void Platform::drawObject(float &time)
{
    if (AHI->animationProcess != 1)
        movePlatform(time, AHI);
}

We can't understand what does 1 mean, without comments. In this situations, we should use enum, like:

enum
{
    LEVEL_PASSING,
    LEVEL_PASSED_ANIMATION,
    LEVEL_PASSED
};

These are just two examples, there is a lot of this in the code.

Not a define - use some constants, like
constexpr double SPEED_MULTIPLIER = 0.00125;
