CopperCube 6.0 released and free now

I just released CopperCube 6.0. One of the major changes is this:

CopperCube is now free.

You can develop games, sell them, publish them on Steam, any App Store, any website, for free now.

In order to support the future development of CopperCube, there are also two additional editions available with a few more features which can be bought: Professional and Studio edition.

The changes in the release are:

You can see a detailed change log here: change log

If you own CopperCube 5 already, you can update to CopperCube 6 here
If you bought CopperCube 5 Pro in the last 2 months, just send me a mail and I'll give you a free upgrade.

Overload Review

I recently bought Overload, a zero-gravity shooter, which you play inside mines in a very small one-man spaceship. If you know the game "Descent" from 1995, then you know Overload: It's basically a remake without the rights to the original game. Descent looked like this:

Overload copies nearly all game mechanics and has modern graphics:

Even the default keyboard and mouse settings are the same.

I played Descent very much back then in the 90ies and loved the game, and even created levels for it. And I really like Overload. I even bought the sound track on steam, because it works nice as background music while programming.

The only shortcomings of Overload is the multiplayer mode: No coop-mode and if you want to play online against random users from the internet, there doesn't seem to be any players online. I tried about 15 times on different days and was only succesful twice.

But apart from that: It's great and much fun.It's worth the 25€ it costs on steam right now.


I just took a screenshot of the exact moment where I realized that I am old now. A few minutes ago:

Nothing more to say. :)

Working on WebGL 2 support

I just implemented WebGL 2, in order to make the images rendered by the WebGL target look exactly like rendered by the native platforms using Direct3D and OpenGL. This worked before (and will be improved in the upcoming update), but with the new post effects feature, it wasn't possible anymore since WebGL 1 doesn't support non-power-of-two render targets. The update to WebGL 2 was worth it:

Looks pretty identical to me, doesn't it?


There is this small simple multiplayer browser game which I am playing from time to time during a break or when waiting for a build to finish: Airmash. It looks like this:

I noticed that a surprising amount of the players on there are developers, too. I can also recommend this game for resetting your brain again when facing a problem, works surprisingly well.

I'm not sure what the business model of this is, though.

CopperCube 6 Steam Page live

I just created a Steam page for CopperCube 6 Game engine:

Yes, the next CopperCube update will be a major one, namely version 6. There will be some things in there which I think most users will really like, but as usual, I'm not talking much about this before release. But there will be a nice surprise at least.

If you have a Steam account, it would be cool if you could help and add tags to the CopperCube Steam page, tagging it as "Game Development" and similar. I think this also levels up your Steam account, as far as I understand.

Also, did you see the video I made? (I composed the music for it myself, btw.) It's a bit blurry unfortunately, but I will try to improve it until the release, which will still take a bit of time.

The same rule as always applies about getting Coppercube 5 now: If you buy it now from my website, I give you a free update to CopperCube 6 as well once it is released.

Now excuse me, I have to continue working on CopperCube 6. :)

Post effects

I am currently working on adding post effects into Coppercube for the next update. It is not finished yet, but some features already partially work, like Bloom:

Needs still a bit of refinement, though.

Multiple selection coming

I'm not sure why I haven't added this feature already long before, but somehow I guess it wasn't high priority enough. But the next CopperCube update will have it:

It was quite a bit work to add this, but it is very useful. You will be able to move, scale, rotate all selected nodes at the same time, as well as editing their properties and similar.

Possibility to try out the Brexit

I just uploaded update 1.2 of Government Simulator. It icludes lots of balancing and simulation improvements, and also a Brexit scenario:

So you can try out if you could save UK after the Brexit.But I think also the Russia scenario is a bit more interesting now, after the balancing changes. You can get the game here on steam.

Working on necessary updates

Adding a tiny change such as a new light model causes a lot of headaches, for example a lot of things in the editor need to be updated in order to work properly with that. Right now, everything seems to work again, it looks like this right now:

But other things like for example the wireframe mode don't work yet. But I'm working on it.
