A6 engine - commercial release V6.31.4 - Nov 18 2004

This is from the Acknex Resource site pages. It is the water shader with physics. I installed the Newton from the A6 downloads page.

After inserting include <ffpwater2.wdl>; into my main script, I get these errors when I build.

Loading demo.wdl.................
<(my.density==0.0)> ffpwater2.wdl 154:0 Error(50): Parameter unknown density Parameter

<(my.density=1.0)> ffpwater2.wdl 155:0 Error(50): Parameter unknown density Parameter

<my.water_entity=0;> ffpwater2.wdl 158:0 Error(29): Keyword unknown my.water_entity

<body=NewtonAddMapEntity (my,0);> ffpwater2.wdl 159:0 Error(29): Keyword unknown body

I tried defining density: var density; but that didn't work. How do you handle errors such as this - keyword unknown and parameter unknown.

If you use "my" or "you", than it isn't a variable. It's a skill and must be defined:

define density, skill99;
define water_entity, skill100;

This error happens because u do not have Newton game dynamics...

just install it, or comment out the lines..
