Summary

UPDATED to ver2!!
- collision fixed!
- it's 100% lite friendly now!

This example shows my method on how to make three-dimensional movement in 2D games, just like in classic beat em ups or brawler games (i.e. Golden Axe, Final Fight, Captain Commando, etc). What three-dimensional movements means is that object not only move around in two planes; x and y (like platformer games, top down shooters, etc) but it move around in 3 plane; x,y,and z. So, in this basic example, I made the player not only can move in 4 directions, but also can jumps, and fall from higher areas. The example is heavily commented, but your question and suggestion is very well come! And don't forget to see the game information/help.

i have a question man, how can i animate other actions within this movement, using the draw command, kind of like walking forward, jumping, attacking, i have a game using this code but every other animation i had programed is dissabled.

If you want to use your own sprites and animation within obj_player, then here is the code, see obj_player 's draw event, and click on the second piece of code, you should see this:

draw_sprite(spr_player,0,x,y+z)//draw the player

Change that code in to:

draw_sprite(sprite_index,image_index,x,y+z)//draw the player

That will enable the object to have different sprites and animations.

Moving against walls is a bit glitchy. I need my character to just face left/right (I'm making a beat em up RPG type thing with a Rogue Galaxy/Kingdom Hearts combat system) and whenever I hold a key against a wall (say up), I can't move along the wall (left or right), and my character slides along it really idiotic-looking.

Hello! First, congratulations on the great example!

Im experiencing the same problem the user above. And also something else: the jumper function doesnt seem to work with me. I exchanged the player sprite and it doesnt work anymore.

It work, but yes, I admit it's still imperfect, but I'll try to modify that. If you want, you can change the code inside obj_player and then collision with obj_wall that's where I put the "Moving against walls" code.

Objects in this example relies on collision masks and bounding boxes, so don't forget to manually set those in the sprite menu. I hope it helps

Looking good! I think you should keep working on this example it could be really good. Much better than i expected it to be.

However the moving along the walls need polishing up abit.

[Pixelated_Pope]

This is a great example. Pressing against a wall is a little slippery/jittery for my taste, but that can easily be tweaked.

EDIT

After playing with it a bit, there are a few things that worry me about actually using a system like this, and maybe you can make some suggestions on how this can be modify for a "real" game.

First off, if your character's are not squares, it can immediately break the illusion. Or, at the very least, if I want my character's collision mask to be around his feet, but his shoulders are massive (Think Hagar), as soon as I push up against the wall, I will clip through and show the tile structure.

Additionally, it was common in Golden Axe and some of the old D&D brawlers to have diagonal "cliffs" that you could jump up or jump down.

I guess what I'm saying is that the example is nice, but I would really like to see an actual, non-cube character and some diagonal walls.

If you want to try and tackle this and need some sprite sheets for a beat 'em up (walk, run, jump, etc) PM me and I can provide some.

So If I want to make a beat 'em up,I must get the code from your tutorial,or what?

No, it's just an example, there's so many ways to make beat 'em ups. And not every beat 'em up use 3-plane movement like this. It's all up to you.

Iol!
looks like this tut is for registered, but that is the only code that requires it I just made it into a comment.
But the movements seem like they are perfect for glass blocks!
still seems to be imperfect.
EDIT:
I see that the depth is constantly changed every time you press up and down, I think this causes the block to slide.
also the shadow is a little crazy, because:
if you're at an edge the shadow should show at the floor!
it would be helpful if that was created

It's UPDATED !! Now there's no idiotic sloppy glitchy collision anymore, and it's 100% lite compatible! Thanks all for your comments.

It's still need improvements though

[creators124]

now any way to make shadow appear on floor when your at the edge?
it would be even more better!
if you don't know how to do it for lite, could you tell me a code(s) to do it for pro?
