2d platform game engine

[paul_nicholls]

Hi guys,
Since end of September when the 4E6 gamdev competition was announced with the elements (ponies, accountants, explosions, crystals) I was planing to write a 2d platform game.

I was completely uninspired till I looked at Traveler's 2d platform game tutorials on his site http://www.gameprogrammer.net/index....c16d458d0014b9, and then later on I found some flash tutorials (tile based games) http://www.tonypa.pri.ee/tbw/start.html.

Thanks to these two sites, I have managed to whip up a proof of concept 2d platform run and jump engine with working ladders and platforms + controllable player, enemy and "bullet" sprite types.

The graphics are just placeholders at the moment to test things.

There is no collision between sprites yet though, but I am very pleased that the platforms and ladders are working nicely



The top middle sprite is the player with some bullets fired in different directions, and the other two sprites are enemies who patrol back and forth - changing direction if they hit a wall or the end of the platform they are on.

The player can jump around, fire bullets, climb up/down and jump onto ladders, and there is also gravity of course :-)

cheers,
Paul.

That's great!

It's nice to see people still have an interest in my tutorials, even though they're quite dated now.
Anyway, I hope you'll do well in the contest.

I found a free png of 2d male character outline 'sprites' online here (gamemaker site - can't remember if registration is necessary)

I have edited a bunch some of them to create a simple humanoid pony character for my game. It contains a character standing, walking, running, jumping, falling, crouching, and getting up (so far)




It is a start, at least :-)

cheers,
Paul

Hi Guys,
I have uploaded a video of the current work in progress here

which now uses my new humanoid pony sprite animations

It won't be ready for the gamedev four elements competition, but I am going to try and finish it anyway :-)
cheers,
Paul

I made it so he slides only when running, adds a bit of interest

Hi Everyone,
I have uploaded the work in progress as a playable demo here http://fpc4gp2x.eonclash.com/downloa...yRebellion.zip

It would be great if people could try it out to see if it is at least playable on their windows machine - I am trying to make it work so far on as many different windows machines as possible.

It uses SDL for the window/input and OpenGL for the output.

Keys are

Keys:

Up           = Jump or climb
down       = crouch
Left/Right = move left/right
left Shift   = Run instead of walk (will slide to a stop if running and you stop left/right keys)
F             = fire

The moving platforms are ignored in collisions at the moment as I am trying to get them working correctly.
You can shoot, but there is nothing to shoot at the moment :-)

All I am interested in is if the character is playable.

Comments are welcome, but don't forget it is a concept test at the moment :-)

Can people post their machine specs if they have troubles?

Thanks for your time :-)

cheers,
Paul.

coming along really nice, character artwork is good and the slide to stop when running is great feature, will this be screen swap based or scrolling platformer ?

Thanks for the nice comments Memphis!

It is going to be a scrolling platformer in the final product, with the view window following the character around - the single screen is just for the test :-)

cheers,
