Irrlicht License?

I want to develop a game in Linux - ok, "develop a game" is a tto strong wording. I want to have fun with developing a game on Linux. But i don't want to use anys eparate engine, as i don't need many of things comonly foun in engines.

Now for the main question: IrrLicht has zlib license. Does that mean, that i am free to use just pieces of code from IrrLicht in my own project, as far as it will be marked as such and prject will be free? What if project iwll became GPLd?

The Irrlicht license is based off of the zlib license.

Don't kwno why my first answer disappear...

But here is second try. I read the license; i just don't know whether "alter and redistribute" means also "chunks of code" and whether i could then use such chunks in GPLD code.

Also, i am not making engine. Just small softwre project, where one of principles is to avoid as many dependencies as possible.

The Irrlicht license is less restrictive than the GPL, you may use it in GPL releases.
But you have to take care of the original copyright, which is possessed by the author of Irrlicht.

If you take "chunks of code" it's the same as altering and using, so the license would apply.
