Title: Triangles appearing when rendering vertexArrays
Post by: LarsXYZ on June 23, 2016, 11:16:23 am

I am trying to learn how to use vertexarrays, but when I try to render them they spawn weird triangles. Why is this happening?

Check the documentation (http://www.sfml-dev.org/documentation/2.3.2/classsf_1_1VertexArray.php) and tutorial on how to use VertexArrays.

You create a vertex array with 25 elements and then you append additionally 25 elements by calling append(). Either don't allocate 25 elements and call append or if you allocate 25 elements you should access them with the indices.
