I got myself stuck again in something maybe not so easy.
I'm trying to create crosshairs in the orthogonal views for my tool-plugin, corresponding to the mouse-position.
In particular I have problems in my "Draw" method, as it seems to be the only place to draw lines into the viewport but only updates as something in the scenes changes: camera, objects, but not the mouseposition.
The mouse position is another problem, as the "MouseInput" method only seems to kick in when one mouse button is clicked.
So while I got this hole process working with clicking and then dragging the mouse, I would really prefer not to click first. In a way this seems so be possible as the internal lighting-tool does something similar, or just selecting polygons or points of mesh results in a highlighting.
Again a short recap what I'm doing:
- checking the mouse position in the MouseInput method (sadly by clicking first), and forcing a redraw by using c4d.DrawViews(c4d.DA_ONLY_ACTIVE_VIEW|c4d.DA_NO_THREAD|c4d.DA_NO_ANIMATION)
- drawing some lines in the viewport according to the retrieved mouse position in the Draw method
Maybe there is an easier or more logical way someone could explain to me.
