Bug with opacity when using drawtext in FlexSim 2017

Hi,

It seems that the opacity is set to zero (making objects fully transparent) in FlexSim 2017 when using drawtext and not giving the opacity parameter. According to the documentation the opacity parameter is optional and before FlexSim 17 it behaved in such a way that the opacity was 1 if not given.

See the attached image. Drawtext also changes the opacity of the following draw3dtext and drawflattext commands. And drawflattext does not seem to be working as it should.

Thank you!

Kind regards,

Axel

We will fix the opacity issue for the next bug fix release.

You are using drawflattext() incorrectly. Put the following code in your Custom Draw trigger to see how this command works:

if(!param(2))
	setdrawnamefunction(80, 15, c, param(1), 1);
else 
{
	fglTranslate(-40, -15, 0);
	drawflattext("Hello World");
}

Hi @phil.bobo

Thank you for fixing the opacity and for correcting my incorrect use of drawflattext. I see that I had not read the documentation properly .

Thank you!

Axel
