project

I'm making a scrolling platformer, and I wanted to make some enemies other than the color yellow. In the project, I made an enemy that, when it enters the screen, turns towards the player, and until it leaves the screen, runs forward.

The enemy turns around when it hits a wall and is affected by gravity; however, when I tested the enemy, it would get stuck on the ground and frantically turn around. I understand why this happens–the enemy doesn't seem to move upwards when it touches the ground so it gets stuck, and since the enemy thinks it's touching a wall, it keeps turning around. What I don't understand is why the enemy gets stuck on the ground. Please help!

most likely because whenever I check,

<(x position) < [0]>

returns false on a fireboy with -76 x
So it's obviously true, so the boolean is contradicting itself. I think this might actually cause lag too. try

<([abs v] of (x position)) = (x position)>

okay but it doesn't fix the bug

The problem looks to be the turn 180 degrees block - why are you doing that?

I hate that script which repeats ‘if touching colour, change y by 1’. Check out @griffpatch_tutor's platformer tutorial for better platformer scripts.

to turn the enemy around when it touches a wall

So if the hitbox is touching the floor it will change direction every time through the loop.

when i remove the block, it still falls through the ground

I was addressing the issue of the enemy switching direction repeatedly - I've not seen it fall through the ground but as long as you're using that script I referred to I'm afraid I'm not going to get involved. That script regularly appears here as a problem and I'm not wasting time on it.

However you may want to check the centre of the hitbox costume.

Thank you for your tip. It was very helpful.

p.s. that was sarcasm

This is necroposting, and it is bad.

You unshared it so I can't help, but what's wrong with this? It just has so many problems which I don't know where they come from, like the hitbox and sudden lag plus somehow (I don't know why) HE SINKS THROUGH THE GROUND. And just to help understand the code, I just added scrolling to Griffpatch's platformer (the one in his tutorial).

Hey folks - this thread is rather old. Please feel free to make a new topic if you have a new question regarding to project scripting. Doing so will make it easier for others to find your question.

It would also be a good idea to share your project and provide a link to it, so others will be able to see what exactly needs to be fixed.
