Re: Outrun with frame counter

Many thx.
i don't know if you can 100% relies on that, i had to time shift the old version, since it does not run so many frames it would be finish later.
I did this so you can compare frames when they are on the same time...

Re: Outrun with frame counter

Well done! ST game logic bug: 1. The car accelerates slowly past 193km/h in low gear. Being in low gear should prevent the car accelerating past 193km/h. 2. In the arcade version acceleration is slower below 193km/h in high gear. I also think the blitter would be best used for the road drawing if p...

Re: Outrun with frame counter

another improvement could be obtained from reducing string's bitplanes count. e.g from four to two. in this instance would that be a no go. i want the OSD to be as close to the Arcade as possible. here is the progress so fare. Some of the printing routines need some optimizations, but it starts to ...

Re: Outrun with frame counter

thanks
it also the conclusion that i came to, but i had to asked one that know this stuff, and i know that you have been working with the blitter for a long time.
i also think its better to save the blitter for the Object and the road :D

thanks again :D

Re: Outrun with frame counter

right now i am not using the blitter for 8x8 char, do you think it would be an advantage to use the blitter for 8x8 chars? it depends on how source data are organized, how many bitplanes should be touched and whether source should be masked with destination. In case of the sky, if I'm not wrong it ...

one place i think i found some that can give some speed, is the string routine. I turn it off, and the frame raise about 2 fps. of cause the new one will also take some time, but not 2 frames :D i will look at it more closely at it, tonight and tomorrow , and also on the print object routine, and s...

Re: Outrun with frame counter

Thanks for the mention Peter! With Outrun on the ST the road is nice and wide and the sprites scale OK. It's just a bit choppy. I think the ST game engine was written by Ian Morrison (Ice Software) and it was later improved for other road games i.e. Turbo Outrun, Chase HQ 2 and Hydra. There might b...
