Leadwerks Engine 0.2.8 - friendlier, easier, more

Run FPSControls.bat:
http://www.leadwerks.com/files/engine0.2.8.zip

This release is more similar to what I envision as the final product. This isn't so much a pimpage demo, but more an example to show artists and programmers how everything works.

Script Editor
A pretty complete script editor with syntax highlighting lets you edit your code and launch the engine. The editor will keep control of the launched process, so you can terminate execution at any time. Error feedback has not yet been implemented.

Physics
Physical objects are now very easy to create in the editor. Place a model in 3DWorldStudio and add a property "phybox=1" or "phycyl=1". You can adjust the mass (default mass is 10) by adding a "mass" property. Use "mass=0" for a non-movable object. The engine will automatically calculate the model offset and center of gravity, even if the model pivot isn't in the center. Add a property "shadow=1" to make any object cast a dynamic shadow.

Script
I've added a lot of commands, including some basic player commands. The demo included shows how to implement controls with both WASD and the arrow keys, as an alternative/secondary key. Open engine.bcs in notepad to see the syntax for all available commands.

Assets
All models have been textured and sized correctly, and will be created with their default texture applied. If you get a chance to look at these in 3D World Studio, you'll appreciate how well-made they all are.

Sorry, I forgot to include a required file. I fixed it and posted a new download, same link.

Oooh.

Wow. Incredible.
Are you working on HL3?
Your engine is one of the best piece of software I've seen!

I'm not going to use this, as I have no interest in creating an fps, but can i say: Well Done ! It sure has come a long way since those early B3d days.

Great work Josh. Script editor is very nice, but having tabs to switch between different scripts would be cool.

Nor me (totally sick of FPS), but this engine could easily be used for games other than shooters. Granted, you'd be restricted to either a first or third person view, but that's true of all 3D games!

..well..Once completed, let me know and I'll buy it..thats for sure..man syntax is almost B3D! I love it..I'm really looking seriously on to this..

It's astouding to see how much this has come along, and the amount of work that must have gone into it. It's been a long time, but the quality is simply amazing!

It certainly seems very easy to use, and more importantly, to understand what's what.

no openal here and your link to openal.zip is down

Thanks for the compliments.

I need to contact Creative and figure out how to tell whether OpenAL is installed or not.

You could use the engine for whatever type of game you want. In the script, you can see that the camera is just manually positioned to match the player.

It's three billion years in the making, but congrats Halo. Runs and looks great.

Very nice release.

But I'm a wrong or is it incapable of exclusive fullscreen?
Because on startup I get the well known overlay flicker (I've ObjectDock) which only happens if 3d apps start windowed fullscreen mode instead of exclusive.

As well, for some reason it seems like the performance dropped seriously since .24 (I get like 40-100 FPS on 1680x1050 on my 7600, 2x2Ghz CoreDuo, so not a that stunning result ... I get the 40 - 50 FPS with Counter Strike Source and everything but HDR active on that resultion and thats more than a room with a few objects ...)

You can change the display mode by editing startup.script. Change the last parameter in the Graphics() command from 2 to 0 to start it in fullscreen.

Dreamora, my guess is your rig is fillrate-limited. I started using a shader on the engine-created materials (where no material file is present) so that all surfaces will work with dynamic lights. You're running at a very high resolution, so it would make sense that would slow down the card a little if a fragment shader is being used.

I would like to know when you are planing to make release this system??

Thats exactly what I did, changing 2 to 0.

Hmm, 7600 shouldn't be that fillrate limited that it breaks down that far, its 128Bit buswidth, 256MB VRAM, so if simple, non parallax nonbump materials is killing the performance that badly, I would say that there is more in the pipe breaking the performance, not just a fillrate issue.
I only get like 200 FPS with the default 800x600 as well, which is quite disappointing for a room with 2 barrels, a few bricks and no demanding shader effects active at all.

Its a very nice engine none the less, .24 and previous (haven' tested .26 and .27) showed some quite interesting aspects and if the fps break in shows some usefull reason or solution, it will definitely be a great thing.

I think it's hard to make conclusions about framerates when it is above 100.

Still not working on my laptop. All drivers are fully up to date.

Describe behavior please.

It's the same as many people have reported, shuts down immediately after trying to link the shader. No error popup or anything.

works fine on my dell latitude d800 laptop here.

Interesting,

It wont work on my desktop - I have ATI Sapphire Radeon 800XL.

IPete2.

Hmmm...the x600, is that a first-generation shader card?

I can't believe how badly shaders were first implemented. The amount of code you need just to emulate the fixed function pipeline exceeds the instruction limits of the first shader cards.

I have a crappy Radeon 9550 I can put back in and test with.

No, it's fully shader model 2.0 compliant.

Will the Leadwerks engine support Mac OS X?

No.

Won't run on my ATI X800Pro either. Gets to the loading shader part and just quits.

Nothing pops up when I click the exe, however I do see the log (Radeon X300/X550):

The problem last time was older drivers but that's probably not the issue this time?

I'll have to pick up one of these cards and see for myself.

Thanks for testing!

this starts sickening me...
none of your demos worked for me.
only one of your early ones using stencil shadows...

Mine too halts at

It's open source. You should be able to include re-distributables and not worry about it.

However, if you need to figure it out for some other reason (supporting multiple APIs), since it's COM based, you can search the registry for it's guid. If it's registered, it should be there, and consistent across machines.
