How do i make a button do different actions?

Scripting Issues

Hey, I was wondering, how do I make a button do a different function each time I press it. Like, let’s say I’m making a text dialog for an NPC, each time I click the next button, it will change the text.

import direct.directbase.DirectStart
from direct.gui.OnscreenText import OnscreenText
from direct.gui.DirectGui import *

from panda3d.core import TextNode

# Add some text
bk_text = "This is my Demo"
textObject = OnscreenText(text=bk_text, pos=(0.95, -0.95),
                          scale=0.07, fg=(1, 0.5, 0.5, 1), align=TextNode.ACenter, mayChange=1)


# Callback function to set  text
def setText():
    bk_text = "Button Clicked"
    textObject.setText(bk_text)


# Add button
b = DirectButton(text=("OK", "click!", "rolling over", "disabled"), scale=.05, command=setText)

# Run the tutorial
run()

I know how to make a button do one function but not different functions each time you click the button.

Thank you.

Hi, I’ve slightly modified your example to show how you could do this.

import direct.directbase.DirectStart
from direct.gui.OnscreenText import OnscreenText
from direct.gui.DirectGui import *
from panda3d.core import TextNode

bk_text = "This is my Demo"
textObject = OnscreenText(text=bk_text, pos=(0.95, -0.95),
                          scale=0.07, fg=(1, 0.5, 0.5, 1), align=TextNode.ACenter, mayChange=1)

def setText():
    textObject.setText("Button Clicked")
    b["command"] = setText2


def setText2():
    textObject.setText("Button Clicked 2")
    b["command"] = setText

b = DirectButton(text=("OK", "click!", "rolling over", "disabled"), scale=.05, command=setText)

run()

Yes, thank you very much.
