        #Sets up the controls
        base.accept("escape", self.escMenu)
        base.accept("f1", self.debugBullet)

but when i pause the mouse is still disabled. Any ideas?

The disableMouse and enableMouse commands are just poorly named and do not actually disable and enable the mouse. What they really do is disable and enable the trackball-type mouse control of the camera.
If you mean that you cannot see the cursor, it just means that you have hidden the cursor and not unhidden it when you want to use your menu.

yea i read about that, and no the cursor isnt hidden but its stuck in the middle of the screen, i assumed that since disableMouse(0 causes it to lock to the middle enableMouse would “unlock” it lol. Is there a way to regain my mouse movement?

check if the mouse is moving by using
mpos = base.mouseWatcherNode.getMouse()
at least then you can work out if its display side or input side.

ok i figured it out, my task

def updateCamera(task, self):
        base.camera.lookAt(self.np)

        pointer = base.win.getPointer(0)
        pointerX = pointer.getX()
        pointerY = pointer.getY()

        if base.win.movePointer(0, base.win.getXSize()/2, base.win.getYSize()/2):
            self.Pitch = -((pointerY - base.win.getYSize()/2)*.1)
            self.Heading = -((pointerX - base.win.getXSize()/2)*.1)

            self.np.setP(self.np, self.Pitch)
            self.np.setH(self.np, self.Heading)

        return Task.cont

wasnt being removed on pausegame, so i remove it then try to add it again and get this error “AssertionError: task->_manager == NULL && task->_state == AsyncTask::S_inactive at line 224 of c:\buildslave\dev_sdk_win32\build\panda3d\panda\src\event\asyncTaskManager.cxx” and that code is right here

def resumeGame(self):
       # taskMgr.add(self.playerList["Player1"].ship.taskTimer, 'ShipTaskTimer')
        #self.props.setCursorHidden(True)
       # base.win.requestProperties(self.props)
        try:
            self.menu.destroyAllMenus()
        except AttributeError:
            print("Nothing to destroy!")
        taskMgr.add(self.update, 'update')
        taskMgr.add(self.cameraTask, "cameraTask", extraArgs=[self.camera])
        base.disableMouse()

and i define that task here

class Camera():

    def __init__(self, nodeToFollow):
        self.attachCamera(nodeToFollow)

        self.thisTask = Task(self.updateCamera)
        taskMgr.add(self.thisTask, "cameraUpdate", extraArgs=[self])

im clueless lol also im not sure why those import header things are turning out wierd on the forums

im still not sure why i got that error but i just made a function inside of my camera task to add the task instead of trying to pass the task variable to another class. at any rate i got it, but im still curious as to hwy i got that error
