comment Are references to other games considered an infringement of copyright?
@anorton: The whole "lawyer magic" thing is a US centric view. I've been trained in copyright law, specifically with the intent of guarding the company against copyright infringement issues. Since local law allows me to give legal advice without passing the bar exam, I didn't bother going that route and I'm not legally a lawyer. But I'm certainly far more capable of giving such advice than any random lawyer who didn't specialize in copyright law.

Not going to downvote you for it, but "consult a lawyer" for every simple thing you do? Have you any idea what lawyers cost? And seriously, this isn't a legal minefield. Copyright doesn't cover everything, as you correctly note. So why worry?

comment Should independent game developers target older hardware?
However, note that the target demographic which buys high-end videocards like the GTX280 is wealthy enough to have bought a new card since. The people who today still use a 2009 era videocard probably bought a budget model back then.

comment How do I control which calculations are done on the CPU and which are done on the GPU?
IIRC, the shaders are compiled on the CPU before being sent to the GPU. And that's done by the GPU driver without the OS.

comment Legality on BSP maps and creating them using Open Source Editor Tools
"Legality" is a misleading word here. There aren't any explicit laws on this; the terms are enforced by private contracts.

comment How do teams prevent overwriting work in source files?
@O.R.Mapper: Getting parent-child relations right is fairly easy. Both versions to renconcile may be assumed to be correct, after all. My main concern would be max-occurs; if two childs are added when one is allowed you have an invalid document.

@MaurycyZarzycki: Changing the same letter is similar to changing the same pixel: that needs manual resolving. .JPEG probably was a bad example, I now realize, because artists don't work on lossy formats. But the merge issue also exists with .PNG. At the very least, you'd appreciate if merge tools would be able to merge XML without breaking it.

On the plus side, locking is about the only way you can edit a .JPEG or other non-plain-text file. This isn't a theoretical limitation, it's just that the merge tools usually suck.

In fact, 3 of the 4 tags are an answer, but one is the answer.

comment How can I make A* finish faster when the destination is impassable?
Re Google, at my previous job we analyzed the performance of Google Maps and found that it couldn't have been A*. We believe they use ArcFlags or other similar algorithms that rely on map preprocessing.

Wrong. A* is very much aware of topology, via the choice of admissable heuristic.

@Zehelvion: details, really, the point is that you establish an upper bound which allows you to prune A* searches, allowing a quicker result in particular for cases when no path exists (but also for long paths near the max length)

@Desty: That's NP in path length, not node count, which is why I explicitly wrote O(nodes) instead of just O(n).

If there are different agents with different rules, but not too many, this can still be generalized fairly efficiently by using a vector of IDs, one per agent class.

comment How can I make A* finish faster when the destination is impassable?
Note that you can determine (reasonably efficient, O(nodes)) for a given graph the maximum distance between two nodes. This is the longest path problem, and it provides you with a correct upper bound for the number of nodes to check.

comment How to describe the performance requirements for a PC game?
This problem is why demo's are very relevant for PC's. "If you doubt whether your PC is fast enough, just try the first level for free." Do put demanding GFX in that level, both to sell your game and to prevent performance problems later on.

comment How can glass breaking effect from Smash Hit be achieved?
Looks fake. The edges are curved unrealistically. Straight edges followed by sharp bends followed by sharp edges again? Not going to happen. Unprepared glass doesn't break in L shapes.
