FPS camera issues

[ctr]

Hi, I'm trying to make an FPS style camera in panda, and everything seems to be going well except that whenever I click any mouse button, the camera moves to another spot and gets stuck, even though I'm using no mouse button events. I am assuming this is becuse I am on OSX and base.win.movePointer() requires MRelative to be on, because if I turn it off, the mouse button doesn't do anything. I'm not sure why this is, and if anyone using OSX can tell me if it's happening with them or fix it, that would be great. Here is my code, it uses the camera and a basic environment:

Code: Select all

from direct.showbase.ShowBase import ShowBase
import direct.directbase.DirectStart
from pandac.PandaModules import *
from direct.gui.OnscreenText import OnscreenText
from direct.gui.OnscreenImage import OnscreenImage
from direct.actor.Actor import Actor
from direct.interval.IntervalGlobal import Sequence
from direct.filter.CommonFilters import CommonFilters
from panda3d.core import *
from math import *
import sys


class Game(object, ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        base.accept( "escape" , sys.exit)

        props = WindowProperties()
        props.setCursorHidden(True)
        base.disableMouse()
        props.setMouseMode(WindowProperties.MRelative)
        base.win.requestProperties(props)

#        self.crosshair = OnscreenImage(image = 'gfx/crosshair.png', scale = (.03125,1,.03125))
#        self.crosshair.setTransparency(TransparencyAttrib.MAlpha)

        player = Player()

        OnscreenText(text="The Game", style=1, fg=(1,1,1,1),pos=(1.3,-0.95), align=TextNode.ARight, scale = .07)
       
        self.environ = self.loader.loadModel("models/environment")
        self.environ.reparentTo(self.render)
        self.environ.setScale(0.25, 0.25, 0.25)
        self.environ.setPos(-8, 42, 0)

        self.pandaActor = Actor("models/panda-model",{"walk": "models/panda-walk4"})
        self.pandaActor.setScale(0.005,0.005,0.005)
        self.pandaActor.reparentTo(self.render)
        self.pandaActor.loop("walk")

        pandaPos1 = self.pandaActor.posInterval(13, Point3(0, -10, 0), startPos = Point3(0, 10, 0))
        pandaPos2 = self.pandaActor.posInterval(13, Point3(0, 10, 0))
        pandaHpr1 = self.pandaActor.hprInterval(3, Point3(180, 0, 0), startHpr = Point3(0, 0, 0))
        pandaHpr2 = self.pandaActor.hprInterval(3, Point3(0, 0, 0), startHpr = Point3(180, 0, 0))

        self.pandaPace = Sequence(pandaPos1,pandaHpr1,pandaPos2,pandaHpr2,name="pandaPace")
        self.pandaPace.loop()

class Player(object):
    speed = 110

Thanks in advance.

Anyone?

It's only been about 3 hours since you first posted. I am not sure about the number of people that use OSX that could help you either. Just give it some time and check back tomorrow.

Actually its been a day and three hours, but I guess there aren't too many people using OSX.

I just pasted in your code and had no difficulty with the mouse button--clicking the mouse button repeatedly had no effect. Tell me more about the precise problem you are seeing. The camera moves to another position and gets stuck? As if, perhaps, the mouse data changed to something strange and stopped coming, maybe because MRelative mode got switched off or something? Try printing the numbers you are getting back from the mouse position every frame.

Incidentally, you should not import DirectStart if you are inheriting from ShowBase.

Thanks David. These are y relative mouse movement values with button clicks marked, although it is obvious something is wrong:

Code: Select all

300 ## not moving
300
300
300
300
300
300
301 ## moving mouse
301
305
308
310
310
309

308

306
304

302

Nevermind about it getting stuck, I can still move the mouse afterwards.

Hello,
I hate to revive an old topic, but I too have ran into the issue with OSX and the clicking problem.

Both my trackpad (MacBook Pro Late 2009 Glass no button track bad) and Magic Mouse (multi touch mouse) cause the program to stop working (getting stuck)

the getP() seems to stop working but the heading continues to work just fine.

If you keep the mouse still and just click the Pitch seems to jump randomly in a circle (as in it rotates to some random values)

If anyone has a fix for this I would greatly appreciate this! Thanks!

[liltimtim]

A small discovery, I'm running OSX Lion so keep that in mind. When NOT in fullscreen mode, I can use MAbsolute and the problem is solved with the inverted/random clicking issue however, if I use fullscreen mode the mouse stops working entirely as in my program does not receive input from the mouse at all!

For what it's worth, RMB doesn't seem to work as expected either on OSX in the p3d environment. Might want to add this to the list...

What do you mean 'add it to the list'?
