Go to near the top of IntersectSegmentSphere:

new const Float:b = GetVectorDotProduct( m, d );

lose the const

There is another similar error further down

This also occurs twice

replace `t` with `closestT`.

I also changed IntersectSegmentSphere again (the last line)

Yeah I inserted the code and the rocket didn't do anything when I shot it toward the sphere area.

You want to hook SetTransmit on the rocket. something like: (not sure if tf_projectile_rocket is correct, or if you need to unhook when it dies)

public OnEntitySpawned( entity, const String:classname[] ) {
        if( IsValidEntity( entity ) && StrEqual( classname, "tf_projectile_rocket" ) ) {
                SDKHook( entity, SDKHook_SetTransmit, OnThink );
        }       
}

I know I did have it like that

Did you fill in the bits I left out (dealing with spheres/lastPosArray) :p

I tried that's why I added you to see where I put my sphereradius and coord

Sorry, busy weekend...

The spheres array should contain tuples of the form (x, y, z, r).

eg

addSphere( const Float:pos[ 3 ], const Float:radius ) {
    const Float:sphere[] = { pos[ 0 ], pos[ 1 ], pos[ 2 ], radius };
    PushArrayArray( spheres, sphere );
}

Use a model, and hooktouch it.
Why make things harder than they need to be.

Does model use bounding box rather than sphear?

And if you want to do accurate reflections with that you will need to perform backwards tracing and everything else my code does anyway.
