Ok so heres the project https://scratch.mit.edu/projects/647056719/
whats happening is its drawing everything fine, but its lagging so much, and i have no other idea how to do it. please help me!

Is the “forever” block inside of your Fluid myBlock necessary? I removed it, and the drawing seems to work the same. The lag seems to be coming from the pen constantly drawing and erasing the water over and over.

Yeah, I also took out the forever loop from your Fluid Custom Block and it stopped lagging and kept working!

Remember that the

set pen size to ()

block exists.

Also learn about optimization, that's useful too.

What i need to do is constantly draw a new one so i can add water effects. thats why i had the forever loop

I assume you're wanting to make the water bob up and down, like waves? You could look for a more efficient solution, such as erasing top layers and adding top layers, so that you're redrawing a much smaller chunk every tick, or just using a larger pen size in general to reduce how much you redraw.

oh ok.
