Synchronous operations that run within a coroutine still execute on the main thread. However, it’s important to remember that coroutines aren’t threads.
In situations where you would like to use a method call to contain a procedural animation or a sequence of events over time, you can use a coroutine. This means that any action that takes place within a method must happen within a single frame update. In most situations, when you call a method, it runs to completion and then returns control to the calling method, plus any optional return values. In Unity, a coroutine is a method that can pause execution and return control to Unity but then continue where it left off on the following frame. As you can see this gives us quite an interesting texture.A coroutine allows you to spread tasks across several frames. This will make the line go from thick to thin or put correctly go from a heavy line weight to a light line weight.įor fun I have also filled in the left hand side of the circle so that we end up with a shading from dark on the left to light on the right. By the time you reach the right hand side of the circle you should be using the chisel side of the hairs. On each line, starting at the left with the filbert brush held with its broad width on the canvas, paint a line towards the right, rotating the brush in your hand as you go so that by the time you reach the right hand side of the circle you have turned the brush 90 degrees. To paint the lines I am going to use a soft filbert brush and the same thinned black paint from the hatching. We will draw our lines horizontally inside this circle, so lightly draw in a few horizontal parallel lines across the inside of the circle. In this exercise I have used a pair of compasses to draw a light circle inside the second block. The thicker the line, the more weight it has. The thickness of a line is called it’s weight.
