Water Effect Help

Troubleshooting effects

I'm trying to get water to work in my game, but when I experiment with it, It either crashes, doesn't move, or completely lags the f**k out of me. I'm using a few codes from the JME Tests to get ideas of what to do, yet they all don't look right. (Can't post screenies, Too busy.)



water = new WaterRenderPass(cam, 4, true, false);

water.setClipBias(0.5f);
water.setWaterMaxAmplitude(3.0f);

water.setWaterPlane(new Plane( new Vector3f( 0.0f, 1.0f, 0.0f ), 0.0f ));
watergrid = new ProjectedGrid("Water ", cam, 100, 70, 0.01f, new WaterHeightGenerator());

water.setWaterEffectOnSpatial(watergrid);
rootNode.attachChild(watergrid);



Any ideas? (Yes, I'm a total newb at jME  :D)

does the watertests included in jme work? how does your scenegraph look? what are you setting as reflected scene on the waterrenderpass?

It doesn't work at all or just lags me to hell  :smiley:

4

can't help you if you don't at least answer those questions, or post some code of your setup…what graphics card do you have by the way?

1.) They work, but some are laggy. None of them show any kind of texture whatsoever.

2, 3.) Not sure

6

sounds like your graphicscard doesnt support FBO's(what we use for render to texture). what kind of graphicscard and OS? tried updating your drivers?

7

ATI Radeon XPress 200 Series. Windows XP Professional Media Edition.

Will update today and post back.



Edit: Unable to find drivers for ATI Radeon, so I can't get anything there x-x

I'd also like to express when I load that water effect, The game just goes completely black and doesn't load at all.

This is the output:

Anything odd with this? It lags my computer to hell x.x

what are you crazy ? you can't have any 3d accel without the drivers for your card.



Run the demo if it doesn't work there is something wrong with your comp. Otherwise …

Well it still lags me, but at least it moves. Now the problem is that its not showing the texture, but thats explainable (No texture file to begin with!!)
