BGE Realistic Forest/Landscape Demo [Blendfile]

Game Engine Works in Progress and Game Demos
41

blender 2.72b
A whopping 2 fps, 90% of frametime spent on logic and a “uniform initialization is not allowed in GLSL 1.10” message on the console. And it looks gorgeous.

Wow ok I can see what I can do, do you have the version with the moving grass? Because this takes a lot more graphic power. I could try to optimize it someday.

43

It’s not the rendering stage, there’s something in a python script that is draining the game engine cycle but I have no error messages about that. It’s weird that I’m the only one noticing it.

update:

the uniforms are xPos e yPos in LScatter.txt (changing from uniform float to float makes the AMD drivers happy again)
And I think it’s the wind, it’s the only thing that can actually suck up all the logic.

You could probably only process x patches of grass per frame and have it look nice and run fast,

Just have a list and a property[‘Index’] and only process every other patch per frame, or 1/8th

At 60 fps it should still look pretty good.

Hm I´ll check for the Light Scatter Filter. Also I´m not a coder at all, so BPR I´m afraid I don´t know how to set up what you were talking about :frowning:

            Length+=1

    own['index']=0
    own['Length']=Length-1

    X=5 ## will move 5 items per frame
    while(X>0):
        if own['index']>own['Length']:
            own['index']=0
        Target=own['WList'][own['index']]

            if Target['Flip']==False:
                Target['upDown']+=1
            else:
                Target['upDown']-=1               
            if Target['upDown']<0:
                Target['Flip']=False
            Target.worldPosition.z=Target.parent.worldPosition  .z
            Target.applyMovement((0,0,Target['upDown']*.1),1)       
        own['index']+=1
        X-=1
