render world

[AggrorJorn]

I'm trying to create a world that is specifficaly used for the inventory and mission tab. But i'm not getting anything on screen. I'm using the following code in the loop

if KeyHit(KEY_M)==1 then
	if missionWorld == 0 then
		mworld=CreateWorld()
			if mworld==nil then
				Notify("Mission World FAIL.",1)
				return
			end
		DrawRect(GraphicsWidth()/2,GraphicsHeight()/2,50,50) 
		missionWorld = 1

	elseif missionWorld == 1 then
		missionWorld = 0
	end
end	

fw:Update()
time=AppTime()

fw:Render()
mworld:Render()
       --Render(mworld)

       SetBlend(1)
       DrawText(missionWorld,0,400)
       SetBlend(0)
       Flip(0) 

 

The mission world is active because the text in screen changs correctly, but there is nothing drawn. How should I use the render command?

I think all your 2D drawing commands need to be right before Flip() AND after the rendering of the world. What you have it seems to draw the rect but then later you render the screen, which I'm guessing is drawing the 3D world over your rect.

You are right about that. Is it even possible to create 2d images or text inside a created world? I would like to have all the code for creating the image or text inside a different lua file instead of the main loop so I really hope it is. i'm trying to create it in a world so that it is easier to remove.

[Rick]

I think it's possible. I think camera in one of the worlds needs to not erase itself so it'll show through. As long as you draw 2D stuff after the render of that world it'll be on top of that world. But drawing worlds on top of worlds overwrites unless certain things are setup.

Don't the 2D commands draw directly to the BackBuffer? I'm not sure if they even look at the world that's active.

[Rick]

That's true, unless they draw to the current buffer. Not sure.

[AggrorJorn]

Creating another world while using the flip hook functions results in that the image drawn on screen doesn't go away when you are back in editing mode. But apart from that: how do you even remove an image or text that has bin drawn on screen ?

As far as I know it does, which is why you have the draw commands just before Flip()

[Rick]

I think it draws on the current buffer. Because you can create and set a buffer and use DrawText() on it. The name tag function Lum created in Gamelib does this.
