Drawing A Bar Graph

Scripting Issues
1

Ok point me in the right direction again … I need to draw a semi-transparent bar graph on my main window. What construct would I use to draw the simple little box? I use LineSegs for line graphs and that works fine …

Thanks,
Paul

Try CardMaker.

Oh man awesome, THANKS!

Bar Graph Creation …


	cm = CardMaker('DecorationCard')
	self.mThrustCard = render2d.attachNewNode(cm.generate())
	self.mThrustCard.setScale(0.03, 0.2, 0.8)
	self.mThrustCard.setPos(-0.97,0,-0.95)
	self.mThrustCard.setLightOff()
	self.mThrustCard.setColor(1.000, 0.788, 0.000, 0.5)
	self.mThrustCard.setTransparency(1)

	self.mVelocityCard = render2d.attachNewNode(cm.generate())
	self.mVelocityCard.setScale(0.03, 0.2, 0.8)
	self.mVelocityCard.setPos(-0.90,0,-0.95)
	self.mVelocityCard.setLightOff()
	self.mVelocityCard.setColor(0.522, 0.910, 0.800, 0.5)
	self.mVelocityCard.setTransparency(1)

Bar Graph Update …


	ts = self.__MissileExt.getScaledThrust()
	self.mThrustCard.setScale(0.05, 0.2, ts)

	vs = self.__MissileExt.getScaledVelocity()
	self.mVelocityCard.setScale(0.05, 0.2, vs)
