This article mainly shows you "how to solve the Unity custom component sequence frame playback component problem", the content is easy to understand, clear, hope to help you solve the doubt, the following let Xiaobian lead you to study and learn "how to solve the Unity custom component sequence frame playback component problem" this article.

We know that there are two ways to play sequence frame animation in unity. The first is to use the animation component of Unity to play. We just need to select all the pictures we need to play in the project directory, drag them to Hiercarchy, and Unity will help us automatically create an animation clip, and we can use animation components to control our animation, but the pictures created in this way are of Sprite Renderer type. The second way is to create an Image component, use the code to create a sprite, write a piece of code to use the Update function to replace Image's sprite frame by frame to achieve animation playback. This kind of words may be troublesome, but with a higher degree of freedom, you can write code according to your own needs.

As a result of the recent project needs to use a large number of sequence frame animation and logic processing, originally intended to use Unity's own Animation components to achieve, but because Party A needs to change again and again, need to deal with too much logic, in order to facilitate modification and expansion, so according to the needs of their own project customized a sequence frame playback component to assist development. First paste the picture to see the effect, such as the following figure is the ImageAnimation script component, we just need to create an Image, and then mount the script, will need to play the picture to the script Sprite array, according to their own needs in the editing panel to set the image loop playback mode, playback speed, and whether to automatically play, but also according to their own needs to add callback function. It's convenient.

All right, no more nonsense, on the code, the script is open to play Play (), pause Pause (), stop Stop (), replay Replay () four public methods, as well as a callback function, according to their own needs to directly call these four methods and callbacks to control their own picture playback control. The script is not very complex, mainly hope to provide you with an idea, in the project development can be based on their own needs to encapsulate some functions to assist their own development, in order to improve efficiency. This is the end of this sharing, you can communicate and discuss with me if you have any questions and opinions, and learn and make progress together.
