I am very new to Panda3D, and I have an assignment project that needs to be submitted soon.
However I do not have any idea on how to make my character jump up and back down again. I have only made him walk around so far. And I am kinda stuck on how and where to start to script him jump.

Here is my script so far

class World(DirectObject):

def __init__(self) :
        
        self.jimXPos = 3
        self.jimYPos = 0
        self.FrameNumber = 0
        self.jimZRot = -0.3
        self.jimZPos = -0.3
        
        self.accept('w-repeat', self.goForward)
        self.accept('s-repeat', self.goBackward)
        self.accept('a-repeat', self.rotateLeft)
        self.accept('d-repeat', self.rotateRight)
               
 
    def goForward(self):
        angleradians = self.jimZRot *(math.pi/180.0)
        deltaX = -1 *math.sin(angleradians)
        deltaY = 1 *math.cos(angleradians)
        self.jimXPos+= deltaX
        self.jimYPos+= deltaY
        jimActor.setPos(self.jimXPos, self.jimYPos,0)
        jimActor.setHpr(self.jimZRot,0,0)
        self.FrameNumber+=1
        jimActor.pose('walk',self.FrameNumber)
        
    def goBackward(self):
        angleradians = self.jimZRot *(math.pi/180.0)
        deltaX = -1 *math.sin(angleradians)
        deltaY = 1 *math.cos(angleradians)
        self.jimXPos-= deltaX
        self.jimYPos-= deltaY
        jimActor.setPos(self.jimXPos, self.jimYPos,0)
        jimActor.setHpr(self.jimZRot,0,0)
        self.FrameNumber-=1
        jimActor.pose('walk',self.FrameNumber)
        

        
    def rotateLeft(self):
        jimActor.setHpr(self.jimZRot,0,0)
        self.jimZRot+=4
        self.FrameNumber+=0.2
        jimActor.pose('walk',self.FrameNumber)
        
    def rotateRight(self):
        jimActor.setHpr(self.jimZRot,0,0)
        self.jimZRot-=4
        self.FrameNumber-=0.2
        jimActor.pose('walk',self.FrameNumber)

jimActor = Actor.Actor(MYDIR + “/jim.egg”)
jimActor.setPos(3,0,-0.3)
jimActor.setHpr(0,0,0)
jimActor.reparentTo(render)
jimActor.loop(“walk”)
w = World()

main loop

Can anyone help me out? Tell me or show me how can I make my character jump ? Thanks
