Sad replanning

People asked me for Rockbot 2.

I listened. I wanted.

I then asked for help. Just a little, just some ideas, a few drafts.

No one answered. Not a single one.


This is a one person project, no matter what I do. And this person here started on a new job that takes 9h/day and lots of effort, meaning no free time to create graphics.

Unless I win the lottery and have money to pay an artist/designer, a Rockbot 2 won’t exist. What I will do is keep pushing slowly some updates and improvements in the game core, change some features and invest a lot in the editor.

Want Rockbot 2? Then start making graphics, mockups or ideas, even if you just draw with a pencil, and send me to

But Rockbot 1.1 and 1.2 WILL happen.

1.0.1 is out

Rockbot 1.0.0 released!!


After five years in development, several 0.1 versions, a lot of betas and one RC, we finally are ready to launch the first stable version of Rockbot, 1.0.0!




It still have some bugs, issues and improvements in mind for the future, but we worked really hard to fix all important problems and this new release is solid and contains a ton of fixes and small touch that make us very proud. There are several Mega Man engines out there, but you will find Rockbot’s unique features as really great multi-platform ports and an editor that allows you to change almost all aspects of the game a plus for people looking not only to play a game, but also to create their own.


You can get the binaries and source-code in the downloads page, a famicom-like manual can be accessed from here.

  • Several other fixes

Windows Installer Package

Added a Windows installer package to the downloads page.

Almost there


It is with enormous pleasure that we do the kick off for version 1.0 our our dear game/engine, Mega Man(Rockman)-style. In a long journey we faced several obstacles working on each person free time without any gains, but happy with the acknowledge that Rockbot already received, even without a real stable version.

Rememberings aside, what the RC in this version name means? RC is short for Release Candidate, a version already stable and polished enought to even becode the final release; that is not the case of Rockbot, as we already have plans for a second RC. In short, no new features to be implemented, no critical bugs (except for a feew platform-specific) must exists until the final version to be released, after what we start working on 1.1 that will be just an incremental release, nothing radical.

A warning for Android users: due to a limitation in the native SDK, you must uninstall previous version before installing a new one. We are looking for a solution to this issue, so users can upgrade it normally.

  • All stages were revised and improved
  • New port for Nintendo Wii (thanks to Akira Faganello for testing)
  • Platforms now have some nice animation when activated
  • Editor supports “beaten” mode to see how finished stages will look if revisited
  • Editor can swap stages order
  • Better weapon balance and vulnerabilities
  • Fixes for Dynamite when he uses freeze on player
  • Direct correspondence between stage-number and weapon-number
  • Fixes in colorcycle
  • Clean editor code to remove several uneeded pointers
  • New images for Android on-screen controls
  • Reordered stages (skullcastle#1 was the 5th one)
  • Fixes for weapons not showing in the weapons-menu
  • Freeze weapon shoots normal projectiles after activated
  • Improved intro
  • Improved ending
  • Better intangible timing after hit (both player, enemies and bosses)
  • Improve config menu, ask for restart when changing video mode, change keys.

As usual, the game can be obtained from our downloads page.

Hunter’s First Post

Hello, I am Hunter Trammell, an artist helping Iuri with his amazing game, Rockbot: Kyoto Evolution!!


Though while I did have fun playing the game, I think I had more fun re-doing the art, and working on some new art.

But again, this game is AMAZINGLY AWESOME. But be warned; the game is as Tough As Nails! Are You?


The Kyoto police-bots are going to win this fight! Even if they lose all of their lives and Health packs in the process.

This game is well-coded, however there are still glitches and bugs to be squished with the Linux Boots.

[I’m a Windows guy, so… yeah..] If you find any glitches in the PC/Mac/Linux or any other ports, please don’t be upset.

Iuri is hard at work on coding this project, and I’m working on the art and my own projects. [Plus highschool]

Using Editor – Part #1

Now that Rockbot is reaching the 1.0 version (ETA first semester of 2014), it is time for other people to start making games by using the editor. As, for what I know, this was only used by me, the user interface can be confusing. So I will explain the basics of editing players, enemies, bosses, objects, maps with this tool in hope someone find useful. The posts on this series will not follow the tab order, but a logical one, as there is no sense in creating an enemy without a map to put them.



Game Properties:


Name: the name of the game you are creating/editing

Special Item #1: Remember Mega man 2 items #1, #2 and #3? Rush Jet/Coil? Same thing. Pick, between the items you created the one player will be able to call upon selecting on weapons menu. The items can be created at “Objects” tab.

Special Item #2: Same as above.

Semi-Charged Shot: The editor allows you to create projectiles at “Projectiles” tab. You must create one that is the semi-charged and set it here. Why this is here and there isn’t the full charged shot? Because this one is common to all players, while the full can be set differently for each player.

Stage-Faces: Remember the Mega Man 2-10 stage select screen with 8 bosses and later Dr. Wily face? Well, here you can set the icon image for each stage. The stage name is editable at “Stages” tab. For each stage, you set an image.





A stage consists of three maps, that can be linked (remember climbing a ladder on Mega man and the screen scrolls up-down slowly? This was a map transition) between themselves. The stage tab edit have a name, usually the boss name, and, for each player, two diaglos; one in the stage beggining and another when reaching the stage’s boss. You can set, in this tab, the stage name, boss name, boss face (that will appear on the dialog, not to be mistaken with the stage select face), answer player is where you select witch player you are editing the dialog for – the boss dialog is the same for them all, but the player text is not. Also stage dialogs is used on start of the stage, while boss dialogs is the one used when you reach the boss room to face him for the first time. If a stage is already beaten, no dialogs will be shown, as the boss room is now empty.

Note that boss face can be any face you like, the player can speak with someone else, like a companion or communication center, like in Megaman X series.





Here you can edit some aspects of the character the gamer will control while playing your game.

Name: Player name. This will appear on dialogs the player speaks.

Hit Points: Hotal damage points the player can receive. Default is 28, we recommend to keep this way or lower only, as the game does not support other values much well because of the number of lines in the energy bar.

Has Shield: If the player can use a shield button to avoid being hit by projectiles.

Max Shots: How many simultaneous projectiles from regular weapon (special weapons taken from bosses hay their own limit) the player can fire up at same time in the screen (one one of those vanishes, you can fire up more).

Touch Damage Reductor: The player can take less damage from touching enemies. Minimal damage is always 1, but if the touch damage is 4 and you set this to 1, the player takes only 3 points of damage reduced from his total energy points.

Jump Gravity: This is the value substracted from player’s jump speed each frame he is moved when the jump if going from ground to up, or increasing speed when going down in the jump. Higher values make the jump shorter, while higher values make is longer and slower.

Jump Speed: initial jump speed. You can combine this value with gravity to make a really slow or fast jump. Player with both and find values you like.

Move speed: how fast the character moves. Two is a value similar to Mega Man, higher is faster.

Can Slide: If enabled, the player will slide can can pass small holes of only one tile size where normally the player can’t fit; otherwise it will dash and the player height isn’t affected by the movement.

Charged Shot: The projectile this player fires when fully charged.

The graphics used by the player can’t be set from the editor yet, instead it uses the pN.png file from data/images/sprites folder, where N is the number of the player, eg p1.png, p2.png.



Mighty no 9


You all know that Rockbot is inspirated by Mega Man (Rockman) classic game series, and I am a big fan of Kenji Inafune, the designer of the series.

So, well, he left Capcom, that later simply killer all Megaman projects, sadly. So, he is now at his own company, and asked US for help! That is it! We can help out to make a spiritual sucessor of Megaman, a game called Might no 9!

So, you can go to Kickstarter page, and donate money to the project, as I already did of course. For just $20 you can get to fund the game and get it for free when it is launched! And more, they will hear US, the funding team, about HOW we want the game!

Cool, isn’t? We could not be happier with the idea, as Rockbot was also created with the same principle: make the platform action old style games alive!

Please, you also need to donate and help! Let’s do something amazing together.
