code compiles without error but doesnt do anything

[master123467]

this code down there compiles without error but it doesnt do anything when i press the W key , when i press the W i want it to change the player_node's animation from STAND to RUN

in the "//begin key press" all the way down "//end key press" is the key press code

Code: Select all

#include <irrlicht.h>
#include <iostream>
#include <audiere.h>
#include <stdio.h>
#include <windows.h>
#include "newton.h"

You are in _way_ over your head. You should really try to learn C/C++ with something more simple than a rendering engine. If you absolutely insist on failing miserably then...

1. You need to instantiate your event receiver.
2. You need to tell the Irrlicht device send events to your receiver.

Also, it might be a good idea to move the MyEventReceiver declaration outside of the main function. It is legal C++, but local classes are a rarely used feature of the language.

look dont tell me to learn c++ yes i will learn it but dont say im way in over my head if u dont no what your talking about

[zeno60]

He does know what he is talking about master. And you really need to take our advice and just learn C++. Just visit some websites even (http://www.cprogramming.com/tutorial.html) or get a C++ for dummies book, anything that will teach you the basics.

Would you want to go out and build a house just because you have a hammer and a few nails? Just because you can, dosen't mean you should.

Exactly. Figure out how to use the hammer without smashing your thumb first.

when i said he doesnt no what hes talking about i meant he doesnt no what all i no i no c

Maybe you know C but this is C++ and it seems you don't know any about class handling...

You can define as many classes as you want to, but if you don't create any instances of them they are preatty useless !!!

Your problem is elementary and covert with example #02, #05, #06 and many others of the examples !!!
The examples are verry well documented and you should work through them first !!!
