All you have to do is tap the screen. This tutorial is pretty easy to learn, and can improve your games by so much read the notes and credits for more.
Thanks to: @warfame for the tutorial on YouTube the music: Sneaky Snitch Monkey Swinging Monkeys Scheming Weasel Faster Explanation (don't know if this will hel: The pen in scratch is just like a pen in real life. So, when we put the pen up, it makes sure that the pen won't draw (as you probably already know). When we put the pen down it starts drawing. There are lots of things you could do with pen. You could create pen mouse tails (If I get 20 likes on this project then I will make a tutorial on it), health bars (like the one we're doing now), and even 3D. But lets get on to the explanation about THIS project. When we put the go to x: y: block, we put the starting point at the player's x - the health bar width (100). So that meant that we had the point at 100 pixels to the left of the player's center. And so lets talk about the y now. We kept the y the same because don't want slanting lines. we kept it at the y health bar y position (90). And we couldn't keep the y the same as the player's y, because then the health bar would be IN the player, so we raised it up. then we put pen down and started drawing. We did the same thing to the next line of code, but this time, instead of 100 pixels to the left of the player's center, we did it to the right. Then we did the same thing again, but with the second layer. That's it! I hope this inspired you to make your own projects with pen health bars. #tutorial #healthbar #penhealthbar
