Thanks for the help its so frustrating that when I put all the code in the main it worked yet trying to split it up so can be reused and easier to read etc it broke it now is a complete mess I will post the code in seperate boxes to show you the classes I am trying to get this to run on.
My main class is this... The idea is to be able to declare wall here in a line and then be able to pass values to other classes.

I am then trying to draw the walls an intilise variables etc here
void Enviroment::drawWall(float wallArray[],float boatPoint[]){ glPushMatrix(); glBegin(GL_POLYGON); glColor3f(0.7,0.7,0.7); glTexCoord2f(0,0); glVertex3f(wallArray[0], 0, wallArray[1]); glTexCoord2f(1,0); glVertex3f(wallArray[0], 3, wallArray[1]); glTexCoord2f(1,1); glVertex3f(wallArray[2], 3, wallArray[3]); glTexCoord2f(0,1); glVertex3f(wallArray[2], 0, wallArray[3]); glEnd(); glPopMatrix(); }static Enviroment::Wall InitiliseEnviroment(float testArray[]){ std::cout<<"array 1 is "<<testArray[0]<<std::endl; std::cout<<"array 2 is "<<testArray[1]<<std::endl; std::cout<<"array 3 is "<<testArray[2]<<std::endl; std::cout<<"array 4 is "<<testArray[3]<<std::endl; //there should be the normal calculation in here}
last but not least the normal calculation and collision detection is done here.
I haven't changed this to work with my structs yet and they are still set up from when I was attempting to pass arrays across.

Sorry as it is a lot of code. I am no longer using the collision stuff anywhere to try and make it easier to solve. I have tested the functions individually and the results work and are fine. When I try to link it all together I cant quite get my head around how it works.
I have not included the header files but that is just full of prototypes, except for my enviroment header File. I have also included the struct Wall in there so I can use it elsewhere.
Would it be easier to get rid of the classes I have now that don't work and start from scratch trying to design them to include the struct format?
If so how do I get the values from the struct from one class to another?
Many thanks again you have been very helpful and patient and I am sorry to keep bugging you this.
P.S I have now changed the code slightly with a for loop in the main to add all the elements of wall 1 into the wall struct
for(int i = 0; i<4; i++) { test.wall = wall1; std::cout<<"will this work "<<test.wall<<std::endl; }
It prints all the values out right however it doesn't feel right inputting values like this is that just me being paranoid? would I be able to do in theory test2.wall
= wall2, and just do that for every wall?
