Re: Star Wars Arcade (SEGA, 1993): fixing model1 emulation
04/04/16 02:53 PM


More progress! Collision detection with Imperial lasers and torpedoes working now. By some chance I actually had that working early on, but didn't pay attention as I didn't know there was a problem with it. When finally realized this invulnerability I had already lost track of my changes and it took me quite some time to trace back and find out what made it work. Contrary to what I said earlier vlength function does need coordinate subtraction, and this also fixes flyby debris problem:

Code:

static void vlength(void)
{
float a = fifoin_pop_f() - tgp_vr_base[0];
float b = fifoin_pop_f() - tgp_vr_base[1];
float c = fifoin_pop_f() - tgp_vr_base[2];

a = (a*a+b*b+c*c);
b = sqrt(a);
c = b - tgp_vr_base[3];

fifoout_push_f(c);
next_fn();
}


Regarding collision detection with the environment, when f60 function is set to output: 2,2,1 instead of 0,0,0 then on the second stage collision kind of works against the left wall and the floor, but with the right wall and the ceiling only from the outside?! With those same settings on the first stage collision is detected around center of the Star Destroyers, and at some seemingly random points (asteroids maybe?). Interestingly when function f24_swa is set to output 1 instead of 0 collision gets disabled. It's completely unclear to me what is going on, but at least I am narrowing down where to look at.
