Err...no, not even on the previous page. Which library are you talking about? I have his Matrix1Utils thing, and I can't see it really helping much with path finding.

As you are rewriting, maybe you wouldn't mind increasing the camera speed? It's a bit slow. Also, and you probably already did this, but if you are using sync on and sync rate 60 (or whatever), I recommend you change to this:



That's what I put at the top of almost all of my projects. The only drawback with the vsync method is the if someone has their monitor set to 75Hz it will run at 75 FPS.

If you are not using sync at all, I will keel over and die. The absolutely cannot write a game without using sync. If you aren't using it, and after I come back to life, I will explain what it's for.

Fetching link....

Okay... I will make the camera a little faster, but I won't change the sync rate. I use Vsync because that is as fast as my game needs to run, theres no point in making it run faster. I've also decoupled my display loop, so it only runs at about 30fps anyways.

I've been using darkbasic for about two years now, I know why I have to use sync

Thanks for your concern, and thanks for getting this a hot topic

Good news! Pathfinding is starting to work. The unit finds the destination just fine, but it stutters and disappears and teleports backwards etc on the way there, the joys!

Yeah following the calculated path is an other tricky stuff sometimes...

Yeah, Pathfinding in RTS games with ramps, bridges, hills etc. is certainly one of the toughest things, and most frustrating things to do in programming... Don't give up, I'm sure you'll get it nailed

On topic with pathfinding : I just have to marvel at the beautiful pathfinding in StarCraft 2... It's really amazing what they were able to accomplish, and many of the pathfinding bugs from SC1 where eliminated. Anyway, please keep up the good work, this game has awesome potential!

*confused*

I don't understand...

Here is what my sync code example does:



The reason I do this is because DBPro's sync rate command doesn't keep a steady framerate. I just set no limit on it and use the near-perfect vsyncing. It will usually make it run at 60fps and a pretty steady 60fps.

The only drawback is that vsync syncs exactly with the monitor's refresh rate, so if the user has his/her refresh rate at 75 Hertz, it will run at 75 fps.

EDIT: I'm always putting quotes in code and vice-versa

I'm not an expert in this, but if you search for something along the lines of 'decoupling the display loop' you will find a tutorial on what it is. I set vysnc on, which caps my sync rate at my monitor refresh rate.

Then I have a timer within my main loop, which causes it to only sync every 33 milliseconds, meaning it is essentially capped at 30fps, and it should remain constant at that framerate, and there will be thousands of game loop( collision, movement, calculations etc ) per second.

Oh, I understand now. It's just only syncing every second frame, right?

I might use that for increased speed where game logic is what slows it down.

Take a look at this, it will explain better than I will ever be able to lol.

I read it and, yes, I was right.

It basically only updates the screen every 33 milliseconds but runs the gameloop (all stuff like handling input, moving objects, cheking for collision, etc, etc, etc.) as fast as possible.

Hmm....here's an idea.....this would be great for things where you need lots of code to run through lots of times a second yet keep a good framerate, for example, if you had a floor made of thousands of cubes but only wanted to display the ones the camera could see and hide the rest then this would be great!

EDIT: If you are in the UK, just note that we have a Newcastle in Australia too (it's better then your yucky cold and wet one! ).
