Quick update today, as it's Friday and I'm sure we've all got places to be.
The first level baddies are in now, and the particles which show their path.
You can shot them to earn points, but no explosions yet ( That's the next big thing ). I noticed the frame rate drops slightly when the path is onscreen, so I'm going to have to look at that as well ( It's not too bad right now, but when we have a silly number of bullets running every little saving helps ).
Basically I'm trying to get all the costly in terms of CPU / GPU stuff in as quickly as possible and then optimise that so we keep as close to the magic 60fps as possible. I'm lucky in a way that I've got an iPad3 to test on, it's the slowest device out there ( iPad 1 doesn't count, that's really not worth targeting ).
Hopefully Mondays update should have more in the way of particles, as they always look good.
