----------------------------------- zero-impact Thu Apr 30, 2009 3:13 pm 2d Particle Engine ----------------------------------- I wanted to start off with graphics programming in c++ with SDL so I decided to port one of my old Turing projects found [url=http://compsci.ca/v3/viewtopic.php?t=20093&highlight=particle+engine]here. Basically this was a quick and dirty excersize with terrible coding. I'm still learning c++ so I know I probably did a LOT wrong. If anyone dares to look at the code I would be very happy to hear some feedback, no matter how harsh. There is only a linux executable included but you can compile it with [code]g++ main.cpp -Wall -o particle `sdl-config --cflags --libs` -lSDL -lSDL_image -lSDL_ttf[/code] if you have all the right SDL files. If I have time I will post a windows executable later. Screenshot is below. The controls are left click and spacebar. ----------------------------------- saltpro15 Thu Apr 30, 2009 3:46 pm RE:2d Particle Engine ----------------------------------- nice job! I don't see fps limiting in here anywhere, did you do it? ----------------------------------- zero-impact Thu Apr 30, 2009 3:58 pm RE:2d Particle Engine ----------------------------------- No. I think the fps timing code is fundamentally flawed. ----------------------------------- saltpro15 Thu Apr 30, 2009 7:35 pm RE:2d Particle Engine ----------------------------------- hmm, worked for me. your program works fine on my computer at least, compiled under ubuntu of course ;) now go practice for Provincials :p ----------------------------------- zero-impact Thu Apr 30, 2009 7:41 pm RE:2d Particle Engine ----------------------------------- Well it works, it just isn't accurate I think.. I tried to limit the fps but it just got buggy. I should have used a timestep based off of an actual timer to do the physics. ----------------------------------- saltpro15 Thu Apr 30, 2009 7:46 pm RE:2d Particle Engine ----------------------------------- hmm, odd. It still can't compare to my pong ;) we still doing pac-man next? ----------------------------------- zero-impact Thu Apr 30, 2009 7:53 pm RE:2d Particle Engine ----------------------------------- I think I remember you saying you would never post your pong game on compsci.. Anyways back on topic! ----------------------------------- saltpro15 Thu Apr 30, 2009 8:00 pm RE:2d Particle Engine ----------------------------------- hmm, true :p but I really don't have anything to say on topic, so I think i'll just ramble on in this thread for a while until I decide it's time for a coke. it's time! ----------------------------------- zero-impact Thu Apr 30, 2009 8:01 pm RE:2d Particle Engine ----------------------------------- >.< ----------------------------------- zero-impact Sat May 02, 2009 3:45 pm Re: 2d Particle Engine ----------------------------------- Ok I finally got the time to compile a windows version. So here it is for anyone who is interested. ----------------------------------- ecookman Mon Jun 01, 2009 7:17 am RE:2d Particle Engine ----------------------------------- Blah this is soo fun to play with...too fun DUN Dun Dunnn
