Proudly presenting Volcanox:

About

Volcanox is platformer that takes place on a distant planet, coded entirely in my own programming language. Our hero is stranded alone with a volcano in his path, and he must find a way out! There’s only one level and enemy, but it’s a fairly long level and the enemies are annoyingly hard. So plenty of replay value. There is an end for those brave enough to get there. It also times you, so you can share results with your friends.

I put up a small homepage for the game as well, so it’s not lost in this blog.

Install directions

Windows:

Extract and run the executable: volcanox.zip

Other Platforms:

Issues

After speaking to some Windows players (after the deadline) I’ve found out that some of them have a problem with moving, where one direction is faster than the other. I also have heard of an issue where the sound effects break after playing initially. I was unable to reproduce any of these problems on my development machine (linux) so my apologies to those who encounter these problems during their playthrough.

In a previous post, we mentioned that we spent the first 24 hours doing nothing constructive other than putting together our intro screen. There were a few reasons for this:

1. We didn’t have our workflow set up. We hadn’t decided on what frameworks and libraries to use, so for the first 8-10 hours we were trying to use a custom framework that only one person really understood. After deciding that it was rubbish, we switched to yet another -even stranger- framework that I don’t think anyone at all understands. It wasn’t until after 24 hours that we decided to rip all of the complex stuff out and replace it with something with loads of documentation that everyone could grasp in minutes.
2. Our team structure was unclear. Our team was originally far too big. I think that we were originally going to be 7 or 8 people. It’s really, really hard to manage a group like that. Especially when you’re spread out across timezones. It wasn’t until about half of the group had defected that we could really start focusing and getting things done. If your group is larger than 3 or 4 people, I would advice splitting it into two groups instead.
3. Coordination problems. This ties into the above mentioned point, but it can be equally as much of a challenge even in a smaller group. Because we were spread out all over the globe, some people were never around when the “core” of the team were awake. While we were unconventionally organized with proper game design documents (okay, so maybe not proper design docs. But they were better than post-it notes.), it was still hard for everyone to know what had been done and what was going to happen next.

It wasn’t until we had solved all the above problems that we were able to get started, but once we did that, I’m amazed at how efficiently we worked and how everyone stepped up and took care of what needed to be done. The team did great and I would certainly not mind working with them again (albeit in a smaller group). I’m very much looking forward to participating in another Jam, but I hope that in the future there will be a competitive version of it. Making games together is damn fun, but it does feel a little anticlimactic to have worked so hard and then just have your game sit there.

As for the game itself, I’m pretty happy with it. In the best of worlds, I would have liked to have implemented a highscore and prerferably a way to upload that highscore to a central server, but what the hell. It’s a game about beating bulls down to a pulp.

Before signing off, I would just like to thank all the LD:ers for an amazing time. I would also like to thank all the members of the LÖVE-PARTY for their hard work. And finally, to my incredibly supportive girlfriend who kept comparing my cowboy hat to a vagina and my bull to a turd: I will have my revenge…

It's not a vagina nor a turd...

If you want to try the game out, go grab it from the game page!

Click the pretty screenshot to see a gameplay video!

As was explained in a previous post, the objective is to destroy all cattle by catching a bull with your lasso, swinging it around your head and smashing all the other bovine scum to pieces – preferably as quickly as possible!

We were off to a horrible start, and after the first 24 hours, none of us really thought we’d get anything done in time. But here we are, some 45 hours later, and we now have a pretty cool little game! A proper post mortem will be posted tomorrow, but for now, we’d just like to get some sleep. Have fun playing the game and please do leave a comment.

Go play the game!

The LÖVE-PARTY, out!

The premise of the game is rather simple. You play the role of the manliest cowboy to have ever walked in hot pink boots. With your vagina-resembling hat, your mission is to lasso a roaming bull, swing it around and use it as a flail to destroy all the other bulls running around. Why? Well… Ehrm… To make ground beef, I suppose? The only bullshit is the one we’re catching.

Our graphics aren’t all that snazzy (our bulls are rather turd-like, and they have no legs) and there’s not really a game yet. But what you can do is lasso a bull and dance with it!

A deadly -yet graceful- weapon

Next up is probably making stuff collide. Can’t make a hamburger if you can’t smash bulls into each other! With roughly 33 hours to go, it seems like the LÖVE-PARTY might actually be able to create something as awe-inspiring as LÖVE itself.

Who are we, you ask? Today, still wanted by the government, we survive as coders of fortune, if you have a problem, and no one else can help you, and if you can find us – you can hire THE LÖVE-PARTY!

The lesson on this would be, use time in the middle of the nightmares to do these brainless activities, because what can go wrong while build a menu ? =)

2. draw in the paper build and color in the computer
That helped alot, I save my day manipulate the lines with inkscape, but … in order to slice images I have a nightmare with inkscape, go with Gimp works as a breeze

3. dont split images, let the engine split for you
ahhhh I spend some hours cutting images lol !!, could use something like http://love2d.org/docs/love_graphics_draws_1.html to draw a subsprite of the image …

4. make physics work for you
Oh Well after the physics hit me in the head, I learned some details and was able to make it work in a decent way, special note for the boats that hang around over the sea, for that I created a sequence of x,y that is the path to the boats, and I try to follow the path, I believe if I make the water line as an object and change its group to only colide with the boat would be the best to move the boat around.

5. clean the tables in one place only.
Not sure why, buit when I was removing items from my objects list in teh collision handler the LOVE was just crashing … workaroiund that I found : flag to items to be removed and remove in the update() method and one by one from each table, this is call at the end of the update() for each cleanable table :

[code]--- clean the tables
function cleanTable(table2Clean)

for n=1,table.getn(table2Clean),1 do
if table2Clean[n].dirty ~= nill then
table2Clean[n].poly:destroy()
table2Clean[n].body:destroy()
table.remove( table2Clean, n )
break
end
end
end
[/code]

and at the collision handler, I dont remove the pig from the list, just flag it
and I believe that this would be a nice way to animate the pig booom =)
by using a multistate, like alive/almost dead/dying/im outa here
would change the image section, or play an animation … and at the end remove from the list
that would be great …

[code]
function killThePig( id )

love.audio.play( audioCollision, 1 )
pigsKilled = pigsKilled +1

for n=1,table.getn(pigs),1 do
if pigs[n].poly:getData() == id then
pigs[n].dirty = true
break
end
end
end
[/code]

6. reusable files should be in a folder
I’m using for labels the .lua classes that I made called LOVEly-eyes, but I had this problem with the Text object that wasnt transparent … Oh well I went in the code changed the super class, Rectangle to handle this and the Text is transparent by default, cool, but but but … after that I just copied all the files from the LOVEly-eyes folder to my game folder … too bad because I copied a main.lua file together … If I wasnt using subversion would be a nightmare … now LOVELy-eyes are in a separated folder =)

7. use a version control system
I used subversion, saved me when I made an stupid folder copy … revert and just lost some minutes of work… bu remember keep on committing =)

8. put together a zip with everything
Better that just the .love file, create a package with the execs, the best would be create an installer.

9. level up level up !!!
people like rewards, so more than the score I should add level concept, just with faster attack of the pigs, or a different scenario with different speed .. hummmm that would be cool a .lua file for each level

10. collision has 2 sides … A and B
It took me some time to realize that A and B collision data, first they are the DATA from the polygon nothing else, just disconnected data, not a reference, not and pointer … hehehhe string data what makes very nice and unplugged from the code, and you have to test both sides, if wherever A colide on B and the oposite, this was my colision code

[code]function collision(a, b, c)

if string.starts(a, "pig") and string.starts(b, "battery") then
killThePig( a )
removeTheBattery( b )
elseif string.starts(b, "pig") and string.starts(a, "battery") then
killThePig( b )
removeTheBattery( a )
elseif a == DIODONTIDAE and string.starts(b, "food") then
eatFood( b )
elseif b == DIODONTIDAE and string.starts(a, "food") then
eatFood( a )
end

end

function string.starts(String,Start)
return string.sub(String,1,string.len(Start))==Start
end
[/code]

note that I used start() because I add the object id after the type, so I can grabb it from the list, something like “crap_2″, “crap_3″

11. scroll the view is possible Luke… use the force !
Ha ! not the force, at the end I solved the screen scrolling with a simple solution, calculated a shif from the main character and update this shift in the update() method and every single draw has this shift. So the camera is following the character, thats stays in the screen all the time, and to avoid the char to drop outside the world I add invisible walls on left and right side and check if the cameraX is in the possible range,

this in the start of the code

[code]
startCameraX = love.graphics.getWidth( ) / 2
startCameraY = 200

cameraX = -startCameraX
cameraXLimit = {}
cameraXLimit.start  = 0
cameraXLimit.finish = -2905
[/code]

+ cameraX on each draw
[code]
love.graphics.draw(diodontidae.image,
diodontidae.theChar:getX() + cameraX,
diodontidae.theChar:getY())

------ draw the batteries
for n=1,table.getn(batteries),1 do
love.graphics.draw(
imageBattery,
batteries[n].body:getX() + cameraX,
batteries[n].body:getY(),
batteries[n].body:getAngle() )
end
[/code]
this on the update()

[code]    cameraX = startCameraX - diodontidae.theChar:getX()

-- keep the camera in the boundaries
if cameraX > cameraXLimit.start then
cameraX = cameraXLimit.start
elseif cameraX < cameraXLimit.finish then
cameraX = cameraXLimit.finish
end
[/code]
