javascript - Using canvas to change pictures causes flickering problem.

Question

When I use canvas to make a small game, there are pictures that need to be switched, and flickering occurs, but it doesn’t always happen, sometimes and sometimes not. What’s going on?

Answer 2

Solved: Make the picture into a sprite image. Just change the shearing coordinates when switching
