[Callbacks in LEO]

Hi,

 

Could someone please give me an example of how to create a callback using LEO? I currently have the following (non-functional) code:

 

ball.cpp

 

ball.SetCallback((byte*)paddle->EntityCollisionCallback, ENTITYCALLBACK_COLLISION);

 

paddle.h

 

void EntityCollisionCallback(TEntity source, TEntity destination, byte* position, byte* normal, byte* force, float speed);

 

Thanks!

[Programming overview]

As far as I can see C# and C++/Framewerk/LEO are correct.

 

On a different note: what program did you use to create those diagrams with? I have been looking a for a tools that does UML, preferably free or less than 50 euro's and not Visio.

 

Thanks!

This may perhaps not be the case since you're using a custom exporter but I had to find out the hard way that physics do not affect auto-generated PHY files. You might want to try generating them yourself using phygen.

You can add the target platform without hacking the project file. You'll just need to flip some switches which are disabled by default in all Express editions. Go to:

 

- Tools

- Options

- Projects and Solutions

- Check "Show advanced build configurations"

 

Now right-click on your solution and go to the "Configuration manager". Under "Target platform" chose "<New>" and add the x86 platform.

 

Then you should be good to go.

Thanks for the message Josh. My server blocked your message though Appearantly I had it configured to disallow exe's even when the file was in fact clean.

 

Anyway, Davaris sent me a link so I do have it now. There was no license file in the zip so I can't say whether we're allowed to distribute it.

[Font Studio]

Hi,

 

I tried to download Font Studio today but the website mentioned on the wiki (http://www.nitrogen.za.org/projectinfo.asp?id=12) is down.

 

If someone has the installer available, it would be great if it could be uploaded to the board.

 

Thanks!

[C# Headers Main Thread]

You need to set your target platform to x86 and all will be OK. The DLL does not need to be recompiled.

 

Cheers!

[Programming overview]

Ah I didn't consider people customizing Framewerk.

 

An attempt to clear up the confusion:

 

Framework - In C# and C++ this is plain old Framewerk compiled into the DLL. No need to include files other than "engine.cpp", or, in the case of C#, "Leadwerks.DLL". BlitzMax does not have this. Not customizable.

 

Framewerk - Plain old Framewerk, separated from "engine.dll". In order to use Framewerk you will need to include the appropriate files in your project ("Framewerk.cpp", "Layer.cpp", "Renderer.cpp", and some other file I possibly forgot). Customizable.

 

Also, again, I do not dare make any assumptions about LUA.

 

Hope that cleared it up a bit

[Programming overview]

Framewerk is no longer a separate component, it has been integrated with the DLL. If you would include "engine.cpp" in a project you would automatically be able to use Framework. Only BlitzMax has a separate module for Framewerk I believe. Not sure though since I don't use BlitzMax. I also can't judge about the LUA part.

 

Additionally, C# does not use "engine.h" but "Leadwerks.dll" which is a .NET assembly by Ubu (Lazlo on the previous forum).

 

Also note the namechange, it's "Framework" now instead of "Framewerk", except for BlitzMax because appearantly, modules can't be named "Framework".

 

Otherwise looking fine

 

Cheers!

[fw.Main.camera and Pivots]

Thats why I worked for me so well then, had skyboxes turned off because of the ATI driver bug and no transparency in my scene

 

Good to find out now.

 

Cheers!

[Direct Maya Exporter?]

I export to OBJ from Maya, then to GMF using obj2gmf and have no problems whatsoever.

 

Disclaimer: this was about six months ago and I have switched to Silo now.

[fw.Main.camera and Pivots]

Sounds like a perfectly fine approach. I see no reason why you couldn't parent the Framework camera to a pivot. I have previously done so myself when I created an RTS camera.

[where is the chat go to?]

What do you mean by "on every topic".

 

Why would you want a chat box on every thread (doubtful if it is even possible)? What use is a forum then if the solutions to problems are not retained

[Chat program, get it now]

Without having downloaded the application (I'm at work, can't be downloading chat applications ), can anyone tell me if this will run on Linux, possibly using Mono? I would be happy to start a server but my VPS is running CentOS 5.4.

 

Cheers!

[Terrain Erosion!]

I love how you politely answer his question and then ban his wonderful person. That made me chuckle

 

At least it is of some use to us now

[AddBodyForce not working]

You are right. I'll stop asking silly questions now

 

Thanks!

[AddBodyForce not working]

I implemented a CollisionCallback in order to detect a ball hitting the paddle. I need to figure out what direction it was moving in before it hit the paddle. I suppose I can do so using the normal the callback function provides. What mathgic would I need to pull off in order to do so?

 

I also suppose I need to get the math books out again, lol

[AddBodyForce not working]

I had it auto-create one, it's working now. Thanks a bunch

 

Good to know you can't use those though.

 

/me slaps himself in the face.

[AddBodyForce not working]

Hello,

 

I have continued experimenting with my input handling but now have trouble getting physics to work. My ball (Pong) is initialized like so:

 

Ball::Ball()
{
ball = LoadModel("abstract::ball.gmf");
EntityType(ball, 1);
SetBodyMass(ball, 1.0f);
}

 

After the ball is initialized, Collisions(1, 1, 1) is called.

 

This is the Update method of the ball class:

 

void Ball::Update()
{
AddBodyForce(ball, Vec3(1.0f, 0.0f, 0.0f));
}

 

Setting a breakpoint confirmed it is getting called, yet the ball won't move a bit. If I call DebugPhysics(1) it does show a proper collision hull yet the hull remains red. Anyone know what I am missing here?

[Weapons model pack]

I agree with Lumooja, I would most love to see pack #5.

 

Thanks a bunch Josh

[Controlling the player]

Thanks for in the input all! I will continue to pursue this system and see if I can improve and expand on it.

 

Cheers!

[Workflow streamline requests]

Josh has said he prefers the system he is using so I doubt this will be changed. He say some other game dev company do it the way it is currently and liked it.

 

Or better yet, give us the choice.

 

I agree with Niosop, especially a file watcher that automatically converts any OBJ's would be awesome. We will still have to create the material ourselves though I suppose.

[Model Request]

That's a pretty big request. You are probably better off telling everyone a bit about your project, showcasing some work you have already completed and trying to get an artist on board.

[Controlling the player]

Quick class diagram attached:

 

Main loop calls Update, which calls the paddle's Update, which class the Controllers Update, which controls the paddle based on code in either the Player or AI class.

[Controlling the player]

You are being confused with the fact the names are the same

 

Replace all instances of "Controller" with "PaddleController" or something. I do not intent to code a replacement for Leadwerks's TController.

 

I do intent to extend the functionality of with specific AI algorithms, correct

 

Cheers!
