Blitz3D+ Command Reference

SetWorldEditorViewProjection view,projection[,span#][,active]

Parameters

view - live World Editor view handle

projection - projection kind:
1: perspective
2: orthographic

span# (optional) - horizontal orthographic extent in world units, 0.002 to 200000; 24 (default)

active (optional) - whether this view draws pointer/marquee overlays; True (default)

Description

Sets the projection used by live rendering and picking.

Requires the host capability view.orthographic.v1; simultaneous views require view.multiple.v1. Each view keeps its own camera and projection. FreeWorldEditorView releases only that view's presentation target. Selection highlights remain visible in all views; active controls only the pointer overlay.

Handles are context-owned and reject stale or wrong-kind values.

For the full story, see the Debug World Editor guide.

Requires Extended mode.
