Minimap and scene rendering..

[Chiblue]

I am building a minimap in my project, I have the code working but my problem is trying to isolate the scene drawing function, All I want to project within the map is the scene from the editor file, and none of the ingame entities like players or vehicles...

 

Can someone please tell me what engine function is used to build the basic scene and terrain for the camera render?

You can choose which elements to render:

So when I set my stencil buffer to the active buffer, and then call renderworld... makes sense, thanks...

 

Probably a stupid question but, the entity_??? options are the entity types defined within the LUA script for constants?

[Canardia]

Yes, the constants defined in scripts/constants/engine_const.lua are the same ENGINE_xxx constants as used in other languages.

Thanks thats a big help..

How does this work in Gamelib, the render command from the framework does not allow a list fo entities?

[Canardia]

The RenderFramework() command is only used for the main rendering, you can use many mini-renders with your own RenderWorld() and RenderLights() commands (mirrors, dynamic cubemaps, maps, etc...).

I built this function that works within a seperate pure opengl code... but when I put it into my LE project it oes not work... and I believe that the issue is that I am not rendering to the stencil buffer, does anyone have any suggestions how I can do this?

 

glViewport(0,0,size.X, size.Y);

       glStencilFunc(GL_ALWAYS, 0x1, 0xff);	
glStencilOp(GL_KEEP, GL_KEEP, GL_INCR);

glColorMask(false, false, false, false);
glDepthMask(false);

drawCircle(0,0,size.X/2,30);

glColorMask(true, true, true, true);
glDepthMask(true);

glStencilFunc(GL_NOTEQUAL, 0x00, 0xff);
glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP);

RenderWorld(ENTITY_TERRAIN);
glStencilFunc(GL_EQUAL, 0x00, 0xff);
glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP);

Why don't you render your minimap to a Texture right after loading the scene, before loading any dynamic entities? This way, just render an image with that Texture later.

I was hoping for to be dynamic... incase I add other entities that I want in the map... Also for fire by wire missiles (a little off yet) I want to create a panel that shows the flight and allows some control over the missile path...
