I don't know if i'll actually follow through with this, but i've been trying to come up with an idea for the contest. So far i've got a small engine written, i'm not sure what will really come of it though. Originally i wanted to try making one of those games where you have to dig in the ground to collect items/weapons, kill bad guys, etc., but i sorta tossed that idea. I haven't changed the name of the source file, though, so that's why the project's still called "Digger".
Now what i've got in mind is some sort of graffiti game, i was thinking you'd have to go around collecting paints, dodging police (and maybe rival crews), finding nice walls, etc. It's not all mapped out, but i'm thinking something like that would be feasible.
And a screenshot:

There are still quite a few glitches with the jump detection, but for now it supports tiles with variable (Z) heights (you can see the two tables, one has a height of 8 the other a height of 4, and the trash can has a height of 5).
Anyway, we'll see where it goes.
-
By the title, i thought this was going to be a Dig-dug clone. I think your new idea sounds pretty cool though. I'd like to see how you implement it. Would it be goal based? Open world? Randomly generated? There's a lot of different things you could do with this. :D
-
That's actually what i originally wanted to do, but i couldn't figure out a good way to implement erasing just part of a square. I may end up going back to it later.
I'm thinking you might have to achieve certain goals before passing a level (things like painting large murals, collecting certain items, etc.) or maybe adding in a points system based on the number of "colors", size, etc. Perhaps also the longer you stay in one area painting the more likely someone is to call the cops, and if you leave an area too long what you've started to paint will get cleaned up or you'll lose reputation points for leaving too many tags half-done. I'd also like to add in some action such as fights, chases, etc.
It's not all very clear yet, but i'll be trying to figure it out as a go along. :)

The graffiti game idea sounds fun and the variable tile heights are an awesome feature!
-
That is looking awesome so far, great job! :D

Yup. Now I feel like breakout is not gonna compete well. <_<
-
Well, i think you're much more likely to finish breakout than i am to finish this ;)
Anyway, for now i'm going to try to fix some of the bugs with the collision detection and add a little shadow to help make the jumps look a little better. I'm still a little unsure how to pull everything together, but i'm starting to get a vague idea. One thing at a time, i guess :)
EDIT: Also, i was thinking that this engine might work nicely for a skateboarding game...
-
If you can add slopes then definitely. ;)
-
i love the behind-tile masking =D. how are you managing that? just drawing less of the player sprite if there's a tile in front?
-
Tiles that can be walked behind have a special mask. Walking behind the small table works, too, and you could also have something like a gate or a net where it's not exactly a straight line. Really i just check the tile(s) beneath the player and redraw those tiles if they are tiles that should be masked.
-
That is an amazing engine! The first time I've seen jumping in a 4 way scroller!
Streetwalker: I don't think I want to compete with it either!
-
Thanks, it's pretty simple and doesn't really slow down the engine any. I hadn't seen it in any games with jumping for the 83, either, but you've gotta check out Robot War 2 (http://www.youtube.com/watch?v=TeAXO-DW_Cw) for the 82, by DigiTan!
-
wow, just wow that game O.O

That sounds pretty awesome, hope you can hash it out. :D I think this engine could potentially work for a skateboard game as well.
-
Wow, you've got a lot done already, and that screenshot sure is appealing. I hope you finish it one day, even if not in time for the contest.

Or a(nother) MineCraft clone. You'd have to add camera rotation (not all angles, just 0°, 90°, 180°, 270°) but that could work.
-
I'm going back to the US today so it'll probably be a few days before updates. See you all in a few days :)
-
Have fun in the us! Where are you heading? :D
-
To Virginia.
On the plane ride i had a long layover so i managed to fix most of the bugs in the collision detection and added in a few other little things. I also started working on handling graffiti and figuring out its data format. I also keep writing for some reason "Graphi-TI" ;)
Here's the latest screenshot:

stop blowing my mind :P
-
Just WOW . Especially love the shadow Under the player ;D
-
That's looking very nice! =D
-
Yup, awesome ! :D
-
Thanks everyone :)
Someone suggested maybe moving the camera a little with the player, so i added that in quickly:
(http://www.mirari.fr/Gfho)
-
Not much to say other than "looks great!'. :D
-
Yeah it definitely looks good!
-
that is awesome :D
-
I specially love how the camera doesn't totally follow the player. Ut's a nice detail you added!
-
Hey, i've been super busy lately and haven't had much time to work on it, but i got the graffiti working alright today:
(http://www.mirari.fr/uSmU)
-
Looks nice :D I wonder what it will look like at the end ...
-
wait, you an draw graffitty on grass? O.O
Anyways, it's looking nice! :D
-
I've still got to implement the tile detection to make sure it's only being drawn on appropriate tiles (essentially walls) and i'd like to add a little sprite of a spraypaint can (and perhaps a little spray animation) when painting.
Due to the camera view, i'm not sure if it'll be possible to paint left/right/down. I don't know what you all think about that..? Or if you've got an ideas i'd love to hear...
I'll try to clean this up a little bit and add in cops.
-
Well, i just sent in my entry. It's definitely not complete or really even that fun, but the engine's pretty interesting i think. There're a couple bugs, namely with offscreen sprites. I spent the past week or so trying to write a nice pathfinding routine and in the end just gave up. I probably shoulda just left it long ago and worked on other things (levels, fighting, etc.). Oh well. Good luck to everyone!
-
I'll always be amazed by those awesome camera movement. Amazing work :)
-
/me hopes you'll still finish it even though the contest ended
But seriousley, i only want to play around with those controls alone O.O
-
Thanks guys. I've still got a few other projects to finish up, but i'll get around to it. I also wanted to post another screenshot showing the different height levels you can have. It's still buggy, but here you can see it in action.
I'd also be interested in talking about possible pathfinding routines, i've been wracking my brains the past week or two and haven't come up with anything satisfactory.
-
my brains
O.O
Looking nice anyway. :D
-
For path finding, I have only successfully done it on a tiled maze. Essentially, I had the human player and the non human player 'chasing.' Chasing is done by moving in the optimal direction to be closer to the human player. The trick is when the chaser gets stuck, I would draw on some other buffer marking the position and the chaser would not be able to stay on that tile, so they would move backwards or left/right and each tile visited for the next 8 or 16 turns would be marked as well and they would remain marked for 8 or 16 turns (think of a snake from a snake game being placed on the other buffer growing for 8 or 16 turns, then shrinking).
This allows the chaser a little more intelligence to get unstuck, and when you have multiple chasers, the others can avoid getting stuck, too, while potentially taking other routes. I actually got the idea from a cellular automata experiment where I had a few hundred cells navigating a maze and the majority of them were able to find the exit. That, however, is too taxing on the CPU for use in a game on these calculators.
I wish I still had a working example :/
-
Hmm... thanks for the ideas. I thought of sending out "rays" to check for walls, and if you come across a wall walk towards the first walkable tile, but it's got a few weird quirks that don't quite work too well.
-
That's cool O.O will it do anything else? Different levels and more enemies?
-
I've been thinking of letting you fight the cops, upgrade your tags (make them bigger, for example) add a score system, and perhaps add in level objectives like in Tony Hawk (having a time limit to do certain things, like collecting paint cans, painting certain areas, getting X points, etc.). It's very much a work-in-progress, so we'll see. For other enemies, all i can think of are security guards or maybe a special anti-graffiti squad, rival crews, etc. I'm all ears to any ideas.

It's sound very great !
How you want to implement cops fighting though O.O ?

the "rival crews" thing is a great idea. when graffiti first started to be a big thing, there were fiercely competitive gangs fighting against one another to take all the best spots in cities. more established crews would "toy" with the upstarts (write over the top of them), but, if the young crews tried to "background" their betters, they could end up being killed. adding in different types (i.e. tags, burners, top to bottoms, back to backs) would also be fun.
-
For attacking cops/other enemies you would just pick up items (like bats or knives) as you go, maybe stash them in a backpack or just be able to hold one thing at a time. I initially wanted to add in other graffiti types, in particular larger tags and burners. The sprite routines and tag data is set to handle different sizes. I was planning on using [Y=] to [Graph] to let you pick/set different tags/burners. I'm wondering if there'd be a more interactive/fun way to go about it, right now you have to hold down that button (currently only [Y=] works) to continue painting. I was thinking if you spend too long away from a tag before finishing it it'll get washed away.
I'm also not sure if cops should attack you by default or only if they catch you doing graffiti. Also, attacking a cop might make them call in for backup, which might mean a spot gets hot for a while and you need to either lay low or leave the area for a while. I also like ideas of having attributes, again similar to Tony Hawk, where you can do things like paint faster, carry more paint with you, run faster/jump higher, etc.
Lots of ideas, just gotta start working them in.
EDIT: i'd also like to try to reuse this engine to set up a skateboarding-type game. I can foresee a couple problems (apart from probably being limited to 8 directions), but i think it'd be fun nonetheless.
-
Very interesting idea. I also like the graphics. :D
