The AI Extension is here! šŸ’“

I usually use them as a condition! So ā€œif output >0.5 then press buttonā€. Not sure about the letters, as it should only give out numbers 0-1!

help

i have no idea what Iā€™m doing. Iā€™m trying to get the net to run away from a sprite. its not working one bit.

hideous code warning :arrow_heading_down:

Actually this works fine in principle, just a few bugs:

    1. You mixed up mysprite and mysprite2 quite a bit, I made it so the dog is always the one running but I realize maybe the meat was supposed to be running XD You could switch the images around anyway!
    1. You were using the distance between the sprites as an input between 0-1 by dividing by 100, but because the meat is only following at speed 10, the dog can get more than 100 pixels away- I fixed it so the sprites are in a 10*8 tilemap with walls around the edges so the maximum distance is always 160, so dividing by that ensures the input never goes over 100!
    1. I also changed the wya you assign velocities. In the original a value of 0.5-1 would get a speed of 50 - 100, but a value less than 0.5 would get a speed of 0 - -50. (This subsequently discludes values 0-50 and encourages fast positive velocities more.) Instead, I subtract 0.5 from the output first to limit the speeds to 0-50 and 0 - -50 respectively!
    1. This is something iā€™m fixing with the update- the base ā€˜random netā€™ function in my original extension is far too overpowered and usually outputs way higher than average. I added a ā€˜mix with empty netā€™ block to just push all of the weights closer to 0, so there is more variability at the start!
    1. Another error with my extension- it has dramatic pause a BIAS!!! Yeah, because the weights inside the net can ONLY range from 0-1, the neural net has a huge bias to output higher for higher inputs and lower for lower inputs (even though you want the opposite in this case.) In my much-needed update, ALL inputs, weights, biases, and outputs will be range from -1 to 1 to allow for negative relationships.
    1. This isnā€™t really an error, but because the dog can only ā€˜seeā€™ the distance because it only has that as an input, it can never tell from which direction the meat is coming from. If you tried to evolve this AI, it would probably learn to just sprint as fast as possible in any direction! I suggest a separate input for ā€˜relative x valueā€™ and ā€˜relative y valueā€™. ā€˜mysprite x - mysprite y / 160ā€™ and ā€˜mysprite y - mysprite2 y / 128ā€™. would get these numbers, but they would be limited to -1 to 1, so you should also divide both by 2 and add 0.5 to limit them to 0 to 1.

TL:DR: Flaws with my extension mixed with some variable mixups and incorrect limits on distance and speed!
Sorry to make learning this extension so hard, I hope to seriously improve it in the update, and I really love that youā€™re dedicated to trying this out and being one of my first students : D

And for anyone dedicated enough to read this whole postā€¦ the estimated release date is tentatively sometime in October! Usually, Iā€™d coincide it with a new 5-minute polished video, but by not making one I can actually focus more on the update and making a shorter video thatā€™s just a tutorial on how to use it.

With my fixes:

  • Iā€™M HYPED!!
  • I plan on using the new extension :smiley:
  • IDK, sounds complicatedā€¦
  • Buttons!

@randomuser can you help me with this reel quickā€¦

I need to have the AI be able to learn over time.
It would be helpful for you to start it because i dont really understand it.
I read the stuff but it didnt make sense.
Please add coments in the project so I can read them when Im editing the game.

hey, could you help me figure out how to use this? I get how it works, built I donā€™t know how to translate that into actual code.

Ah definitely!
Itā€™s quite complicated at the moment, I need to update it to be easier to use XD
What are you trying to do?

I am also interested in neural nets. Donā€™t think I am smart enough (yet) to understand it. :slight_smile:
Maybe have a easy to understand incredibly simple example?

Thatā€™s a good idea, maybe in demo form so it can be easily modifiedā€¦ Iā€™ll get on that! :hammer:

I am mainly trying to figure out how to make some Ai characters move around based on where a ball is and other AIs are, but basically its AI Soccer. hereā€™s an example of what I am trying to do with the follow function instead of the AI.

They changed their username so just paste the link into a regular search engine and itā€™ll redirect to the new url which you can paste into makecode
