... put this in the pixel shader input
float4 fresnel:COLOR0 ...
I have no pixel shader input.
Also matWorld and vecViewPos are not declared.
Here is the code:
Code:
float4x4 matWorldViewProj: register(c0);
texture entSkin1;
texture entSkin2;
texture entSkin3;
vector vecSkill41;
float1 mtlSkill1;
struct VS_OUTPUT
{
float4 Pos: POSITION;
float2 texCoord: TEXCOORD0;
float3 eyeLinear: TEXCOORD1;
};
VS_OUTPUT VS_p0(float4 Pos: POSITION)
{
VS_OUTPUT Out;
float4 pos = float4(1 * Pos.x, 1 * Pos.y - 1, 1 * Pos.z, 1);
float4 pPos = mul(float4(pos.xyz,1), matWorldViewProj);
Out.Pos = pPos;
Out.texCoord.x = Pos.x * 0.5;
Out.texCoord.y = Pos.z * 0.5;
Out.eyeLinear.x = 0.5 * (pPos.z + pPos.x);
Out.eyeLinear.y = 0.5 * (pPos.z - pPos.y);
Out.eyeLinear.z = pPos.z * 1;
return Out;
}
sampler BumpMap = sampler_state
{
texture=(entSkin3);
MAGFILTER = LINEAR;
MINFILTER = LINEAR;
MIPFILTER = LINEAR;
};
sampler RefractionMap = sampler_state
{
texture=(entSkin2);
MAGFILTER = LINEAR;
MINFILTER = LINEAR;
MIPFILTER = LINEAR;
};
sampler ReflectionMap = sampler_state
{
texture=(entSkin1);
MAGFILTER = LINEAR;
MINFILTER = LINEAR;
MIPFILTER = LINEAR;
};
float4 PS_p0( float2 texCoord: TEXCOORD0,float3 eyeLinear: TEXCOORD1) : COLOR
{
// addiere die Geschindigkeit von vecSkill41 hinzu für Wellenbewegung
float2 waterCoord = texCoord.xy * 0.001 * vecSkill41;
// die Bumpmap mit der waterCoord Koordinaten
float4 bump = tex2D(BumpMap, waterCoord) * 2 - 1;
bump = normalize(bump);
float2 mid = eyeLinear.xy / eyeLinear.z + bump.xy * 0.1f ;
// Reflektierte Wasseroberfläche
float4 reflection = tex2D(ReflectionMap, mid);
float4 final=reflection;
// Output
return reflection;
}
technique water
{
pass p1
{
VertexShader = compile vs_1_1 VS_p0();
PixelShader = compile ps_2_0 PS_p0();
}
}

well simply declare the vectors at the beginning  and the pixel shader input goes in this line: PS_p0( float2 texCoord: TEXCOORD0,float3 eyeLinear: TEXCOORD1, float4 fresnel:COLOR0)

Thank you Matt_Aufderheide. The transparency is working now.
But now, I found a bug. The objective of the transparency is to show a little of what is underneath of the water. Therefore I put a block underneath of the water, because before I didn't have anything there. Only that now it appears another reflection layer above the water.
In this pic, you can see the bug layer. It only appears in areas that have something under.
Here I am under that layer.
And here, I am above that layer.
