This is even better than part 9 of the tile scrolling platformer. You actually get to learn something here and how to code this for enemy AI games instead of copying code because after a few parts of a project you start to not care so much about the code and only about the final product.

[@trombone28]

In the tile scrolling platformer, if you just copy the scripts, it's your own fault. Next time, before you do, try to understand what's happening, and teach yourself how it works.

[@RedToilets]

@@trombone28 I'm saying that I try to learn something and I copy what griffpatch does. I understand what he's doing but I don't understand how the code does that sometimes. For example, part 6.

[@trombone28]

@@RedToilets I see. What you should do then is try to break apart the code into smaller pieces, and watch the video bit by bit to try and better understand how everything works together, but I get your point.

I'm pretty amazed by the way color detection is used. Also I learned that scaling down an offscreen object wouldn't make him go onscreen again. Very smart design, even though it might create a bit too much lag in a larger scale project because of the clones being used. Also, I think you could make arrows invisible by just making them ghost 100, color detection would still work.

[@suspense_comix3237]

I have an idea on Scratch AI. Basically, there is an enemy and a player. When you start the game, the AI begins it's "BeforeCurrentState" where it goes to random positions and tries to hunt you down. Once you get hunted down, the AI puts keyspots called "LastCaught". Then it begins it's "CurrentState" where it goes towards that "LastCaught" keyspot. If you are there, then the AI goes there very often between runs. If you aren't there, then the AI begins it's "BeforeCurrentState" again.

A few notes: 1. The path's up and down names are reversed, however this is visual. 2. Moving the paths will result in the pathfinders to stop pathfinding. This is hidden by deleting the pathfinders, but it can cause problems for anyone importing it into a game of theirs.
