ZenGL

Aha! Yes I guess I should have expected the image to be critical.

Yeah, fillrate is very critical

The particles demo has a warning not to use it in the source, but it seems to have run just fine for me!

Particles subsystem is not ready for simple use... all parameters are set by code, and there is no emitter manager in ZenGL for now.

Currently playing around with point in poly (which seems to work), but I am very confused with mouse_x()/y() and mouse_dx()/dy().

Here's a scenario:

if(col2d_PointInTriangle(mouse_X(),mouse_Y(),p1,p2,p3)) then
begin
   // Visual response
end;

text_Draw( fntMain, 0, 64, 'FPS: ' + u_IntToStr( zgl_Get( SYS_FPS ) ) +' | '+u_inttostr(mouse_x())+','+u_inttostr(mouse_y()));

The mouse coords initialize to where the mouse was when the game was launched, but never update after.

if(col2d_PointInTriangle(mouse_DX(),mouse_DY(),p1,p2,p3)) then
begin
   // Visual response
end;

text_Draw( fntMain, 0, 64, 'FPS: ' + u_IntToStr( zgl_Get( SYS_FPS ) ) +' | '+u_inttostr(mouse_dx())+','+u_inttostr(mouse_dy()));

Coords output are changing as I move the mouse, but still no collision response.

if(col2d_PointInTriangle(mouse_X(),mouse_Y(),p1,p2,p3)) then
begin
   // Visual response
end;

No collision response

if(col2d_PointInTriangle(mouse_X(),mouse_Y(),p1,p2,p3)) then
begin
   // Visual response
end;

text_Draw( fntMain, 0, 64, 'FPS: ' + u_IntToStr( zgl_Get( SYS_FPS ) ) +' | '+u_inttostr(mouse_dx())+','+u_inttostr(mouse_dy()));

For some reason this works the way I want it to.

Anyway, I can't really find docs anywhere so I'm a bit confused about their behaviors, but at least I got it working the way I wanted after some very random guessing.

The mouse coords initialize to where the mouse was when the game was launched, but never update after.

Did you watch this demo - "02 - Input"? There are few lines of code in function Timer(at end of it) that very important:

  // EN: Necessarily clear all the states.
  key_ClearState();
  mouse_ClearState();
  joy_ClearState();

[dazappa]

I guess I had misunderstood its function based on the source. I thought it only cleared button states, at any rate it works nicely with mouse_clearState.

[Andru]

I thought it only cleared button states

Under Windows it also clearing yet another state, because WinAPI GetCursorPos is slow function, and ZenGL call it only one time per iteration.

New font generator have just released Here the source code of it. Just create directory "tools" in ZenGL directory and unpack archive there. After you can compile it with Lazarus 0.9.29. Little bit later I will provide GNU/Linux and Windows binary archives, because now I want to sleep

Fantastic Project. What about shader?

Thanks

this framework looks elegant , thanks for sharing
but i was hoping that the bin directory is full of exe

[code_glitch]

Thank you so much for the font creator. I'm just curious: but could I use some of your audio and font code in Prometheus? (along with the editor?).

Just a thought, since I can see this speeding up development and making it easier to use. Perhaps even a chance for easy porting from Prometheus to ZenGl if projects get serious even...

cheers,
