What is the Difference between ANIM_hide and ATTR_draw_disable?

In order to understand the difference between hiding geometry and disabling drawing, you need to understand that an OBJ triangle can serve many purposes. Broadly, those purposes are: Drawing (the most basic use). Collision detection, of which we have three … Continue reading

Plugin-Based Prop Discs

I was discussing plugin-controlled prop discs with a third party developer. The developer wanted to know if custom prop disc control would end up inside Plane-Maker. It may end up doing so, but I don’t think this would be nearly … Continue reading

I Feel Manipulated

Tom has a new video on youtube of his just finished Falco. The video shows what screen-shots cannot: that the mouse interactions on the plane are really well crafted. If you’re just discovering X-Plane (or just discovering that X-Plane’s 3-d … Continue reading

The “Airplane Modeling” Datarefs

I have blogged about this before, but I will try to create one simple explanation of what’s going on with sim/cockpit2 and sim/flightmodel2 datarefs. Sandy and I (with the help of others who helped compile the list) created “new” datarefs … Continue reading

Custom Datarefs for OBJ Animation

I don’t usually blog about plugin issues, but this one falls into limbo, somewhere between plugins, aircraft design and OBJ animation. This is written for plugin developers; if you don’t write plugins, you can tune out. Plugin Drawing Plugin drawing … Continue reading
