Smooth Pathfinding Function V2

Download the GEX together with an example

A small function a made i while ago now.
It allows some object to move around smoothly while still pathfinding.
It uses mp_potential_step(), which means it can be customized with mp_potential_settings().
This also means that it SHOULD ONLY be placed in a Step Event, since it only PERFORMS a step towards the goal once per step
More information available in the help file.
Try it and remember: COMMENT AND RATE!

Wow Sounds Just like wat I was looking for
Hmm.. I tried abit of tweaking cud do the trick hmm if you could make it less sensative then 0 would be cool but ive goto test in my game first it could be alright!

I you've noticed the text in the upper corner, it says: Press Up and Down to change the smooth factor.
The smoothfactor is a number witch means the higher, more sliding up walls, but the smaller, the more precise moving around and garanteed found.

I saw that yea that works hmm it may work better with nt so many boxes xD and very good for precise collisions!

Pretty nice, well explained tutorial 9/10.

[Fede-lasse]

That's because i originally wanted to post it in Tutorials And Examples, but i quickly found that it didn't belong there.
And when posting Examples there, you normally have to explain everything to the last bit, and so i did here.

3 bumps.

This is quite nice really. But will it work in an environment where everything's different shapes and sizes and not just squares?

[Fede-lasse]

Sure.
It uses mp_potential_step()

Okay, thanks.
I'm from Denmark, so uh

[Fede-lasse]

Bump, i see that this begins to fade in the shadows

I honestly don't see why this isen't getting many replies, it's great! Next time I start a serious game project (probably some time after Christmas) I'll have to use this for the AI pathfinding!

Well, thank you for doing that , i mean, if this appeared on page 12-15, people would never had the chance of trying this , not that i'm selfish, but you get what i mean.
Also, i'm using this a lot myself, even in a game i'm currently making!

bump. Seems interesting. I'll edit this once i try it out.

too bad the game i'm working on isn't ai intensive. This would work wonders for and RTS. I noticed the occasional glitch where one of the units would move in the opposite direction for a second or so, but overall, it worked very well. 9/10

<{POST_SNAPBACK}>

This is caused by mp_potential_step() which makes an object do these kind of things, because in truth, the object is blind, then the function comes in and makes the object check for a random chosen direction between right or left to check if the way around is there.
EDIT: Oh, well, it's because the walls are placed so thight

Yay! Just finished V2! Check first post!

I'm a little confused... Is this a rewrite of potential_step? an a* potential_step merge, what??

[Fede-lasse]

Yeah, you can say that.

It's mp_potential_step() with some motion planning functions in it, so you should consider it as a faster alternative for mp_potential_path(), which crashes if you don't use it right (mp_potential_path())

If you're still confused, try it out and experiment with it...
