Blade Brothers Engine: Creating my first 2D Game Engine

[LeonBlade]

Sorry I haven't done much, I've been sick lately and haven't had the energy to start work again.
I will soon.

Alright now I'm working on my BBEMap class which will load in a .map file which currently is just this:

Code: Select all

0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0

However, later on I'll be doing some sort of map file structure in a language like YAML as K-Bal suggested.

Currently now I'm just trying to get back in the flow of coding that I was in a week ago or so.
I plan on currently just reading in a line and then exploding the line with the blank space character as the delimiter and then getting the correct tile from the tilesheet and adding that sprite to a SDL_Surface called map and then when I render it I'll just render the entire surface to the screen.

I'll keep you updated within the next hour or so.
Right now I'm going to get something else to eat maybe and something to drink.

Sorry for the lack of quality at first, it's still processing

Hey everyone!
Sorry I haven't updated much in a while, been kinda busy

So here is my documentation on my map file format (I figured doing it in binary is 10 times easier).
Click here to download it and check it out!
Let me know what you think, what I should chance etc.

Click here and you can download the test map.
In a few minutes I'll write some C++ to parse the map file (just some command line stuff).

So check back in a little bit, and again let me know what you think!

Oh shit, that's XCode. I had no idea you were a Mac user, dude.

Great video, btw. I subbed, 5 starred, and favorited.

Haha, yep
And thanks, I hope to be making some new videos soon once I work out the map stuff.

Thanks again for those that helped out, I'll be posting very soon once I get actual tiles down

Great! Can't wait to see it in the engine! I just love seeing other people's game dev videos

[GroundUpEngine]

aha same! I wanna see these maps in action

I'm pretty excited for this.
It's not much, but it's something

[eatcomics]

pretty sick

[LeonBlade]

Oh god... I'm running into some problems.
The Events are slow as SHIT and nothing is instant.

Here is what my event look like:

Code: Select all

void BBEGame::EventLoop(void)
{
	SDL_Event event;
	
	// Game loop
	while ( SDL_PollEvent(&event) ) 
	{
		switch (event.type) 
		{
			// When you want to handle user events
			case SDL_USEREVENT:
				HandleUserEvents(&event);
				break;
				
			// When you want to respond to user input
			case SDL_KEYUP:
				HandleKeyDown(&event);
				break;
				
			// When SDL is quit
			case SDL_QUIT:
				done = true;
				break;
				
			case SDL_MOUSEMOTION:
				//HandleMouseMove(&event);
				break;
				
			case SDL_MOUSEBUTTONDOWN:
				HandleMouseDown(&event);
				break;
				
			case SDL_MOUSEBUTTONUP:
				HandleMouseUp(&event);
				break;
				
			default:
				break;
		}
	}
}

Here is my mouse move:

Code: Select all

void BBEGame::HandleMouseMove(SDL_Event *event)
{
	//SDL_GetMouseState(&mouseX, &mouseY);
	
	mouseX = event->motion.x;
	mouseY = event->motion.y;
	
	int rx = (mouseX % 32);
	int ry = (mouseY % 32);
	
	BBEPoint ps;
	ps.x = mouseX - rx;
	ps.y = mouseY - ry;
	
	myCursor.Move(ps, false); 
}

If I put that in the GameLoop it runs relatively smooth, however doing it like this is SLOW and very unresponsive.
Does anyone have a possible explanation as to why this is happening

[GroundUpEngine]

Dun use case statement they slow as hell for Input stuff, use if statements instead ->

Code: Select all

SDL_Event event;

void handle()
{
    if( event.type == SDL_QUIT )
    {
        quit = true;
    }

   //same for mouse stuff
}

..
while( quit == false )
{
	if( SDL_PollEvent( &event ) )
	{
		handle();
	}
}

[LeonBlade]

Code: Select all

// Event-related functions
void BBEGame::EventLoop(void)
{
	SDL_Event event;
	
	// Game loop
	while ( SDL_PollEvent(&event) ) 
	{
		
		if (event.type == SDL_USEREVENT) {
			HandleUserEvents(&event);
		}		
		if (event.type == SDL_KEYUP) {
			HandleKeyDown(&event);
		}
		if (event.type == SDL_QUIT) {
			done = true;
		}
		if (event.type == SDL_MOUSEMOTION) {
			HandleMouseMove(&event);
		}
		if (event.type == SDL_MOUSEBUTTONDOWN) {
			HandleMouseDown(&event);
		}
		if (event.type == SDL_MOUSEBUTTONUP) {
			HandleMouseUp(&event);
		}
	}
}

Is still slow
