NXC: compile error using DrawLine

hi,
I get a compile error with this code:
Code: Select all
int i, peak;
DrawLine ((i+1)/2, 0, (i+1)/2, peak);
I can't get a help example to Drawline but I assume its
DrawLine(x1,y1, x2,y2).
So what's wrong?
# Error: ';' expected
File "c:\temp\temp.nxc" ; line 47
# 15 ((
#----------------------------------------------------------
# Error: Invalid assignment
File "c:\temp\temp.nxc" ; line 47
# 15 ((i+1
#----------------------------------------------------------
# Error: ';' expected
File "c:\temp\temp.nxc" ; line 47
# 15 ((i+1
#----------------------------------------------------------

Is there a function called DrawLine? I don't think so.
In the programmer's guide, there's only a constant named DrawLine

Maybe you mean LineOut?

I'm just guessing here but I think the problem is that DrawLine is not an NXC API function. It is a constant equal to 15.

LineOut might be the function you are looking for.

Or you could use the SysDrawLine system call function.

sure, thx!
DrawLine, DrawRect, DrawCircle...: I think that was my former Pascal code
