The Unity Model Resource usage process

Yesterday, we studied Animatorcontroller automatic generation in unity. Today, the process is a little more refined, and it complements the use of model resources (ASSETBUNDLE) in an MMO, which is only needed if the model resource is very large in an MMO. If it is a relatively small case, directly into the resources directory, loading prefab is OK, do not worry about these problems at all.

Attach the final modified script. It creates a menu option, selects a folder (or file), right-selects createanimation to automatically traverse all the model resources, and then creates the Animatorcontroller and creates the prefab file. After the prefab has been generated (or at the same time as the build), you can create the Assetbundle on any directory in the disk using the function of creating assetbundle.

Here are a few points to note:

1, the generation of Animatorcontroller and prefab time is not fast, so a conversion model not too much.

2, the original can update Animatorcontroller content will be better, but did not attempt to succeed, so the controller will be created to update prefab, so that the associated information will not be lost (Miss animator)

3. When the prefab is created, the prefab is updated if it already exists. This ensures that other places where prefab are used do not lose their information. Because a new prefab is created, a new UUID is generated so that the original reference does not exist.

4, when the controller is generated, there is a judgment animationclip, if it is casual or running action, it is automatically set to loop mode. This is not handled in the script, it is necessary to make a model of their own model to modify. If you don't belong to an animation in Loop_tag, then you need to set up a loop to manipulate your changes in unity. Originally I wanted to be able to modify it through Modelimporter, but I didn't find the right method. So refer to the way of rain pine, directly modify the properties of Animationclip.

There are several benefits to this resource (assetbundle) usage process:

1, development projects will not be very large. Load the resources with the program's thinking. Otherwise a large MMO, the amount of resources may be a few grams. It will take a few minutes to run unity.

2, Assetbundle can be completely done by Fine arts, the program only care about the use of resources loading.

3, the creation of assetbundle items can be categorized. such as scene art A project, character art a project and so on. This can further reduce the project and reduce the chance of conflict.
