<function name="Start2D" parent="cam" type="libraryfunc"> <file line="107-L111">lua/includes/extensions/client/render.lua</file> <description> Sets up a new 2D rendering context. Must be finished by <page>cam.End2D</page>. This is almost always used with a render target from the <page>render</page>. To set its position use <page>render.SetViewPort</page> with a target already stored. <note>This will put an identity matrix at the top of the model matrix stack. If you are trying to use <page>cam.PushModelMatrix</page>, call it after this function and not before.</note> <rendercontext hook="true" type="2D"></rendercontext> </description> <realm>Client</realm> </function> <example> <description>Sets the viewport then draws on the view with 2d methods</description> <code> local oldW, oldH = ScrW(), ScrH() render.SetViewPort( 0, 100, 50, 50 ) cam.Start2D() surface.SetDrawColor( 255, 255, 255 ) surface.DrawLine( 10, 10, 100, 100 ) cam.End2D() render.SetViewPort( 0, 0, oldW, oldH ) </code> </example>
