Part of my level design is creating a lot of objects, and usually I want to create them with certain properties. For example, most of my terrain tiles have a physics behavior with Immovable set to Yes. However, whenever I create a new tile that tile starts with Immovable set to No, even though literally all of the other tiles have it set to Yes. I run into the same problem with certain parameters on other objects (for example, there's one object that all the instances have 50% opacity, but whenever I drag out a new one from the palette it starts at 100% opacity.)
I can just set these all manually, but when I'm creating lots of objects it's annoying to do so. Is there a way to force the 'default' value for an object type? How is this done?
