CTimer issues [Solved]

[Atraides]

Hi all

Been trying to implement a timer into my game, but i want to be able to stop and start it at will rather than using the device time. So i have tried to use the CTimer class.

Heres my code for it

Code: Select all

 
CTimer timer;
CTimer.setTimer(0);
CTimer.start();
...
...

However when i do it this way i get 11 unresolved externals saying that im redefining functions that already exist in CTimer.

So i tried making it a pointer

Code: Select all

 
CTimer* timer; // = new CTimer();
CTimer->setTimer(0)
CTimer->start();
...
...

This works until we try to use the timer as of course it isnt initalised.
EDIT: BTW when i use new it gives me the same unresolved externals.

So im a little perplexed .. is there a bug with CTimer or am i doing something wrong.

Any help is greatly appriciated.

You need to create an instance of the class CTimer. You can do that in either of these two ways...

Code: Select all

CTimer timer;
CTimer* pointerToTimer = new CTimer;

It sounds like you've created your own class named CTimer, right? Well, you will get unresolved symbols if you fail to link the compiled source for the CTimer class. You probably have a file named CTimer.h and one named CTimer.cpp. You need to compile CTimer.cpp and then the resulting object file needs to be linked with your exe. If you're using Visual Studio, you just add the .h and .cpp files to the project.

Nah, i am just using the CTimer.h that is in the Irrlicht source dir.

Do i need to make my own version of it (.cpp) or can i just use that and instansiate it?

Also i tried your idea and i still get all the unresolved externals.

The Irrlicht timer isn't exported from the Irrlicht.dll, so you can't use it directly. Not only that, but the Irrlicht timer uses shared implementation, so even if you could create several individual timers, any function you called on one timer would affect the others.

You are best off to write your own timer implementation. It isn't difficult to do, and if necessary you could copy much of the code you'd need from os.cpp.

ok cool thanks for your input.

I was leaning towards that anyway as i have read that other people have had problems trying to instansiate the CTimer class.

You can find my solution to that here (Multiple timers): http://www.michaelzeilfelder.de/irrlicht.htm
The website might be a little slow currently.

Thanks for that link..
its the implementation that i found while searching the forums and works quite nicely.
