Partially drawing/hiding a sf::Shape::Line

[phoekz]

Hey

In short, how would I go about partially hiding sf::Shape::Line objects like sprites (setsubrect). The picture below explains my intents.

The map screen is scroll-able so the elements inside this frame are moving and obviously when they reach border of the frame, they will be hidden and not drawn at all.

I think best solution is to calculate the intersection between the lines and the edge of the map display.

(SFML2) Draw the map to a rendertexture and draw that with a sprite onto your HUD/UI.

Wow that was genius, didn't even know you could do that .

You could use glScissor: it will only draw objects which are within a rectangle area.
It's really easy to use:

Code: [Select]

glEnable(GL_SCISSOR_TEST);
glScissor(right_x, bottom_y, width, height);

// draw your stuff

glDisable(GL_SCISSOR_TEST);
