gpu_opcodes: Opcode 244 (DSETLIGHT)

self.Lights[Param1]["col"] = self:Read3f(Param2+4) //Color

should be

self.Lights[Param1]["col"] = self:Read3f(Param2+3) //Color

since you're only reading 3f values as position

This line:

vector2f rect_size,ss:#ebp,ss:#ebp;

produces this:

----> ZyeliosASM compiler - Version 2.0 (SVN REV 0) <----
-> ZyeliosASM: Compiling...
-> ZyeliosASM: Pass 1
-> Error at line 21: Internal error #ASHSXCH (or maybe not, did you insert some weird character into wrong place?)
-> ZyeliosASM: Pass 2
-> ZyeliosASM: Compile aborted: fatal error has occured

Assigning parameters one by one works.

Should it be so?

Yes, because vector2f is assembler macro, not an opcode. You can only have constants as its parameters.
What you want is
mov #rect_size.x,ss:#ebp
mov #rect_size.y,ss:#ebp

I was experimenting with the following code to draw a quick line (for a gauge later on):

dclr;

dcolor c1;
dline linex,liney;


dexit;

vector2f center,256,256;  // center as reference
vector2f linex,50,50;  //line point one
vector2f liney,256,256;  //line point 2
color c1,255,255,255;  //White

And it compiles fine, but then the console SPAMS this error:

entities\gmod_wire_gpu\gpu_vm.lua:577: attempt to perform arithmetic on global 'vd' (a nil value)

Until I undo the screen. I tried out my existing program (which is essentially a complex radar screen) and it was fine (no lines, thin rects for lines). I am using the most latest SVN build as of 10/9/2008

Should not, 4th coordinate is reserved for attenuation, or maybe something else. Light's W component is reserved for brightness.

I can't get the GPU to work.... Everytime i upload a program to the GPU, nothing happens. Even the console is empty. The Screen itself shows GPU Error = 2. I've tried it yesterday too, the console showed the following:

-> Error at line 3: Internal error #SAHZ8, report to black phoenix. Data:
-> ZyeliosASM: Compile aborted: fatal error has occured

Anyone can help me?

Does the GPU's membus work? I hooked it up to 64-store and tried to write a value to it and read it back (assuming it begins at 65536), and got an Internal Processor Error.

I think you mentioned something about this in another thread, but for the life of me I can't find it.

First off, the gpu can't write to the outside world as yet(?).
Secondly, the cpu/gpu doesn't write to a n-store, it writes to a flash ram. Goto the advanced part of the wire menu to find the ram.

I'm fairly certain the 64-store is RAM, it's just small. Certainly works alright with the regular CPU. I think most (if not all) of the stuff under Chips-Memory is hi-speed compatible.

Hello, I keep getting a error on the GPU screen whenever I upload a program to it. I used the bounce.txt program and cube.txt program everytime and it always gives me that error on the GPU screen

GPU Error = 2 ...

Error = Unexpected end of program.

All I do is upload the basic bounce.txt to the GPU, no extra wiring.

I searched the forums and saw no solutions posted. Anyone know what could be wrong?
