Game hangs and needs a process kill after entering a name in character creation.
Code: Select all
SHADER] Loading from /data/gfx/shaders/main_fbo.lua

That seems to be the pertinent part of the log.
I did some poking around and it seems like this is due to a quirk in ATI's drivers. I'll see if I can figure out a fix but this is hardly my strength... Maybe I'll draw a hacker to fix it for me
*EDIT*
Looks like this was an issue for people back in beta6... found a workaround.

What workaround ?

Code: Select all
// float noisy = texture3D(noiseVol,vec3(coord,fTime0_X)).r;
// float noisy2 = texture3D(noiseVol,vec3(coord/5.0,fTime0_X)).r;
// float noisy3 = texture3D(noiseVol,vec3(coord/7.0,fTime0_X)).r;
// float noise = (noisy+noisy2+noisy3)/3.0;
// Center Pixel
vec4 sample = vec4(0.0,0.0,0.0,0.0);
float factor = ((float(blursize)*2.0)+1.0);
factor = factor*factor;
/* if (noisy < 0.25)
{
for(int i = -blursize; i <= 0; i++)
{
for(int j = -blursize; j <= 0; j++)
{
sample += texture2D(tex, vec2(gl_TexCoord[0].xy+vec2(float(i)*offset.x, float(j)*offset.y)));
}
}
}
else if (noisy < 0.50)
{
for(int i = 0; i <= blursize; i++)
{
for(int j = 0; j <= blursize; j++)
{
sample += texture2D(tex, vec2(gl_TexCoord[0].xy+vec2(float(i)*offset.x, float(j)*offset.y)));
}
}
}
else if (noisy < 0.75)
{
for(int i = 0; i <= blursize; i++)
{
for(int j = -blursize; j <= 0; j++)
{
sample += texture2D(tex, vec2(gl_TexCoord[0].xy+vec2(float(i)*offset.x, float(j)*offset.y)));

}
}

Commented out the noise functions.
Not sure if this is related but the attack function seems to be broken too. I'll post the log error tomorrow when I'm not drunk.

I'll wait for the attac log, I have fixed one this may be it, dunno.
As for the shader, can you try to comment it line by line to see what it does not like please ?

Code: Select all

Only seems to happen against the necromancer in the paths of the dead. Haven't tested other casters though. I'll be working on figuring what exactly about the shaders is pissing off my system.
*EDIT*
OK it seems to be
Code: Select all
float noisy = texture3D(noisevol,vec3(coord,fTime0_X)).r;
I get the error if this is uncommented but it runs when this is commented out.
*2nd EDIT*
Looks like 'attack' glitches when a projectile is about to hit.
*3rd EDIT*
I seem to have found the problem. in engine/projectile.lua, line 149
Code: Select all
local x, y, act, stop = self.src:projectDoMove(self.project.def.typ, self.project.def.x, self.project.def.y, self.x, self.y, self.project.def.start_x, self.project.def.start_y, self)
remove ", self" at the end.
