#5158086 Metal API .... whait what

Posted by Ed Welch on 04 June 2014 - 07:29 AM

 

 

Metal's C++ based shader language is an interesting idea. Generics/templates might be fun.

I don't think the shader langauge is c++ based. I never seen a double square bracket in c++. Looks more like object c to me

 

Like these? http://en.wikipedia.org/wiki/C++11#Attributes

 

Ok, I stand corrected :P

#5137164 DirectX 12 Announced

If DirectX 12 has no Windows 7 support, I doubt any games will use it. Who would release a game for an OS that has only 10%  market share?




#5129179 AMD's Mantle API

Posted by Ed Welch on 05 February 2014 - 05:58 PM

According to this blog entry Microsoft are working on "bringing lightweight runtime and tooling capabilities of the Xbox One Direct3D implementation to Windows":

I assume that would be fixing the draw call overhead, similiar to what Mantle does.




#5058541 Is there anything faster than A* pathing?

Posted by Ed Welch on 02 May 2013 - 01:17 AM

If you try to do path finding on a target that's not reachable the A* algorithm iterates through every possible square in the scene, which is very slow. To solve that I use floodfill to check that the target is reachable. The floodfill checks that both start and target squares are both in the same area.




#5052375 Murl Engine VS Unity Engine

Posted by Ed Welch on 12 April 2013 - 02:09 AM

Murl Engine looks very new. They haven't fully listed the features of the engine (does it support shadows, sprites, widgets, etc.).




#4845138 Bug testing Lemmings iPhone Game

Posted by Ed Welch on 05 August 2011 - 12:42 PM

Maybe you simply didn't test enough to find the bugs. I had a nasty intermittent bug in the first version of my game. It took me 8 hours of continous testing before I found it. Also, check the crash logs in iTunes connect.
