Detailed Description

The ScreenLog is used for displaying console messages on the game screen.

The ScreenLog is a visual alternative to the writing messages in the console. This prints out messages directly onto the game screen. Function call to print a message similar to printf(char* format, ...) taking Messages appear on the top left corner. You must include ScreenLog.h header file

Here is an example of how the ScreenLog could be used.

#include "ScreenLog.h"
 
// NOTE: Tank has Vect variable called _position
 
Tank::Tank()
{
    _position = Vect(0.0f, 0.0f, 0.0f);
 
    GameObject::submitUpdateRegistration();
}
 
void Tank::update()
{
    this->move();
 
    // This is where ScreenLog::Add() is called to print a message
    // NOTE: ScreenLog::Add() can be called anywhere, not just here
    ScreenLog::Add("Tank position: (%3.1f, %3.1f, %3.1f)", _position[x], _position[y], _position[z]);
}
 
void Tank::move()
{
    \\ moves tank and updates _position
}
