assigning the mouse functionality to Keyboard events
Hi all,
I am beginner to game development and 3D environment. Recently I have gone through some tutorials(world demos) in viz and found the "duck court" demo interesting. I want to make a change to the existing code. Instead of using a mouse to target the ducks, I want the keyboard arrow keys to take care of that.. The code for the mouse looks like this: #Add a crosshair that is linked to the mouse viz.link(viz.Mouse , viz.addTexQuad(viz.SCREEN,texture=viz.add('crossha ir.png')) ) How should I assign the same to keyboard arrow keys. So that the crosshair moves all around the screen. Thanks in advance. You all have a great day ahead. Thank & Regards, Swami |

You could update the crosshair position when a key event occurs:
Code:
import viz viz.go() court = viz.add('court.ive') target = viz.addTexQuad(viz.SCREEN,texture=viz.add('crosshair.png')) target.setPosition(0.5,0.5) vizact.whilekeydown( viz.KEY_UP, target.setPosition, [0, vizact.elapsed(0.2),0], viz.REL_PARENT ) vizact.whilekeydown( viz.KEY_DOWN, target.setPosition, [0, vizact.elapsed(-0.2), 0], viz.REL_PARENT ) vizact.whilekeydown( viz.KEY_RIGHT, target.setPosition, [vizact.elapsed(0.2), 0, 0], viz.REL_PARENT ) vizact.whilekeydown( viz.KEY_LEFT, target.setPosition, [vizact.elapsed(-0.2), 0, 0], viz.REL_PARENT ) |
