A quick question and a may-or-may not be quick question:
Panda won’t recognise the mouse wheel. I try this, and nothing happens. Am I missing something dead obvious?
if base.mouseWatcherNode.isButtonDown(MouseButton.wheelUp()):
print "Yes!"
elif base.mouseWatcherNode.isButtonDown(MouseButton.wheelDown()):
print "No!"
Is there a simple command to turn an object a set number of degrees towards another object, something like:
obj1.turnTo(obj2, 30)
…and if not, can anybody give a few pointers towards a simple and non-hackish way to code it? I’ve been banging my head on that one for a bit with no luck.
(1) A mouse wheel is never up or down. (Actually, I think the up-event is raised at the same moment as the down-event.) You need to catch the event if you want to know when the wheel is rolled.
Why would you want to avoid events? Anyway, the rolling of the mouse wheel is an event, it’s not a state–it happens instantly, it’s not held down. So asking the question “is the mouse button rolling now” doesn’t make sense.
Unless you’re talking about clicking the mouse wheel like it’s a button. That’s just MouseButton.two().
Events seem a bit shit, is why. You write five times as much to code to do a simple thing to begin with, and then you have to worry about state changes and it’s just nightmare city.
…is what I was going to say, until I remembered from context that you’re one of the guys responsible for developing Panda(?). Panda’s great, really! Just a few quirks I’m getting my head around.
For the record i think panda3d event system is great. I was always a polling kind of guy but the panda3d event system is simple and without surprises i am sold.
