isVisible

[Th3]

I thought some people might make use of this for either custom interaction or checking if entity is visible. Don't mind the ghetto fire entity check.

public class Calculations {
    public static Polygon getModelPolygon(Entity entity, Client client, Model model, int gridX, int gridY) {
        if (model == null) {
            return new Polygon();
        }
        if (entity.getName().equalsIgnoreCase("Fire")) {
            return entity.getPosition().getPolygon(client.getBot());
        } else {
            short[][] screenCoordinates = GraphicUtilities.getScreenCoordinates(client.getBot(), gridX, gridY, client.accessor.getPlane(), model);
            Polygon temp = new Polygon();
            for (int triangleId = 0; triangleId < model.getTriangleCount(); triangleId++)
                try {
                    int triangleA = model.getVertexXIndices()[triangleId];
                    int triangleB = model.getVertexYIndices()[triangleId];
                    int triangleC = model.getVertexZIndices()[triangleId];
                    short[] pointA = screenCoordinates[triangleA];
                    short[] pointB = screenCoordinates[triangleB];
                    short[] pointC = screenCoordinates[triangleC];
                    Polygon aw = entity.getPosition().getPolygon(client.getBot());
                    if (pointA != null && pointB != null && pointC != null) {
                        if (pointA[0] <= -1 || pointA[1] <= -1 || pointB[0] <= -1 || pointB[1] <= -1 || pointC[0] <= -1 || pointC[1] <= -1)
                            continue;
                        for (int xpoints : aw.xpoints) {
                            for (int ypoints : aw.ypoints) {
                                if (pointA[1] <= ypoints && pointA[0] <= xpoints) {
                                    temp.addPoint(pointA[0], pointA[1]);
                                }
                                if (pointB[1] <= ypoints && pointB[0] <= xpoints) {
                                    temp.addPoint(pointB[0], pointB[1]);
                                }
                                if (pointC[1] <= ypoints && pointC[0] <= xpoints) {
                                    temp.addPoint(pointC[0], pointC[1]);
                                }
                            }
                        }
                    }
                } catch (ArrayIndexOutOfBoundsException var13) {
                }
            return temp;
        }
    }
}

    public boolean isVisible(Script s, Entity entity) {
        Polygon polygon = Calculations.getModelPolygon(entity, s.client, entity.getModel(), entity.getGridX(), entity.getGridY());
        if (polygon != null) {
            Rectangle rectangle = new Rectangle(4, 4, 512, 334);
            return rectangle.intersects(polygon.getBounds());
        }
        return false;
    }

    public Rectangle visibleRectangle(Polygon polygon) {
        if (polygon != null) {
            Rectangle rectangle = new Rectangle(4, 4, 512, 334);
            return rectangle.intersection(polygon.getBounds());
        }
        return null;
    }

You could do without the null checks as well.
