Enemy Clipping In Marte Engine

Stock code:

        //if we don't hit a solid in the direction we're moving, move....
        if (e.collide(SOLID, e.x + Math.signum(spdx), e.y - s ) == null)
        { ... move ...


Overridden code:

        // store the entity that we would collide with
        Entity other = e.collide(SOLID, e.x + Math.signum(spdx), e.y - s );
        boolean clipThroughEnemy = false;
        // if there is an entity...
        if (other != null){
                boolean otherIsEnemy = false;
                //iterate through MY_ENEMY if any of the other's types
                // and see if it matches one of our enemy types.
                for (String type : MY_ENEMY){
                        if(other.getType().contains(type))
                                otherIsEnemy = true;
                }
                // if we're invulnerable and the other is an enemy, we can clip
                clipThroughEnemy = (!isVulnerable && otherIsEnemy);
        }
        if (other == null || clipThroughEnemy)
        { ... move ...
