So… I looked at @LaserFoxPro’s [Trail thing](https://forum.makecode.com/t/trail-thing/8890) and I made it into a function: [Trial Example](https://arcade.makecode.com/S92280-41822-32954-57700) However, can someone make it into an extension? Currently, animating the trial is not supported, but I am working to implement that. ---

I have made it into an extension now. do you want the code or do you want me to release a github link to download it? ---

Release a GitHub link. Thank You! ---

Ima call this the Tails extension instead of trails. Just because I read it wrong lol. And therefore i subconsciously thought about foxes and therefore colored the block orange without realizing it before now. It looks like a tail anyways so why not?

Would it be possible if we could set how many sprites we wanted following and Ghost be set as on for the trail? In bigger games it could potentially increase the speed massively and allow more versatility. ---

To set how many sprites you want to follow the player, you need to edit the extension it self, since what @LaserFoxPro did was to make 15 sprites and have the first follow the player, the second follows the first one, and so one. As to making it able to ghost through walls, I think I already added that. ---

Can you make it so it accepts another parameter as speed? As for the extension, I love it! ---

Ghost is another thing seperate from ghost through walls, it massively reduces the number of calculations your computer has to do for checking collision with other objects. I have used it in the past (before the particle extension) to make particles which are still sprites. If this works that could be good. ---

It has been updated now with two new parameters. Speed and sprites. so you can now change how many sprites will be made for the tail. does produce some lag if you set the number too high ---

@Sonicblaston Sorry for bothering you with this, but in the extension, I see an error where if I make a trail but set the speed to 0, in addition to the trial I set, there is another drumstick chasing me, while the trial stays stationary. ---

fixed I think. If I understood your question correctly. the extra drumstick is now gone. but there is still a tail frozen where it spawned ---

Btw if you set the speed higher than the players speed you get some really cool results ---
