convert vector* to float

[ahso]

Hi
I get:
cannot convert MProbeInfo_t*’ to ‘GLfloat’
How could I do such?
Many thanks
Michael

You need to explain some more, as it doesn't make much sense to
convert a pointer to a floating point number.

I want to use it with glVertex3f and I get values like altitude from
that vector:

glVertex3f(lx+1059, ly+749, ProbeResultat)->locZ);

it's declared as:
std::vector<Probe_t*> ProbeResultat;

Many thanks

So, the expression 'ProbeResultat' yields 'a pointer to Probe_t'.
The third argument of 'glVertex3f' (I'm guessing here, OpenGL is not
defined by C++ language), is the 'GLfloat' that you have a problem with,
right? Count the parentheses.

Hi ahso

You have an extra ) right before ->
try this instead:
glVertex3f( lx+1059, ly+749, ProbeResultat->locZ );

what type is Probe_t::locZ ?
