I'm building a video game type thing. It has three touch sensors, for left, right, and fire. The LCD controls where the enemy is. I'm having some problems with my code, so here it is(I'm using kernel 0.2.4): #include "conio.h" #include "dmotor.h" (...) (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

(...) I think you mean if (enemy == 1). Also, the identifier "fight" resolves to the address of the fight function. Doing "fight;" is equivalent to doing "1;". It's legal, but it doesn't accomplish anything. You want to do "fight();" and (...) (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

Thanks for the response! Now I'm almost ready to test it. I just need to know if, when you have a call void function, and you then use the int main() to close the program with return 0;, will the void keep running? Thanks Nick Howell (...) (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

(...) No, it will not. Functions don't work like that, in general. If you want to call a function and have it run independently of the calling function, you must use execi() to start it. (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

I worked on that. I'm having trouble with "execi()" and some stuff related to it. Here's the offending area, but not the entire program: int main(int argc, char **argv) { pid1=execi(&startup, 0, NULL, 1, DEFAULT_STACK_SIZE); MYexit = -1; cputs("x"); (...)

It probably should. But why does it say that "pid1" is undeclared? Shouldn't that be taken care of in tm.h or unistd.h? (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

I just got new batteries for my RCX, so I just did an actual test. I didn't get very far. I don't believe that it is registering the touch sensors. Here's how I had it: if(TOUCH_2 == 1) { do this and that and that; } What's wrong with it? I should (...) (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

I'll try that. I thought it was something or other like this. I'll post when I'm at least partially successful. (24 years ago, 15-Mar-01, to lugnet.robotics.rcx.legos)
