In this tutorial you will learn how to draw a line from specific points with your mouse.
So first thing add a slider by right clicking and you should get a drop down menu like so:
Then click insert object and scroll down until you find the slidebar and then add it to your project.
Now repeat this process but add a sprite this time and name it line. I painted mine black so we can see it a bit better but its up to you, paint your line any color you want!
Now add these events to your event sheet and you should be done!
If there are any problems send me a PM and I will try and help you out! I hope you all enjoy the tutorial and find it useful!
