Irrlicht Engine

When using IImage object, is using unlock after lock necessary if I'm doing drop anyways?
A trivial question but still interesting. I suspect it's not necessary.

Basically doesn't matter at all as unlock() was never used (it does exactly nothing). In trunk we even deprecated it and replaced lock/unlock by a getData() function.

wait, unlock doesn't do anything? Huh... so the call to unlock in my screenshot logic is irrelevant then?

It matters for textures only.

Yeah, IImage::unlock() does nothing while ITexture::unlock() is important.

I will sound dumb but what is that trunk thing I keep hearing? I googled it and found a git repo that has no description other than how to install and stuff. What exactly does it do and how is it different?

We are still using svn. svn repository is here: https://sourceforge.net/p/irrlicht/code/HEAD/tree/
That side should also have the command to check-out trunk which is our most active development branch and will become Irrlicht 1.9
You need a svn client (like TortoiseSVN on Windows).

As for installing:
You have to compile it yourself with the project file and then you got a new dll.
You have to set the corresponding include and library paths in your project to include that.
