Slither.io-bot: Version 0.9.6 is too resource intensive

[dingyang1988]

I am running the bot on Google Chrome Version 50.0.2661.102 m with Tampermonkey.

Starting from version 0.9.6, I notice that the bot has become very resource intensive. Even when running in mobile rendering mode, I suffer a major drop in FPS when in situations with a few bigger snakes on the screen.

With the bot disabled, I'm getting FPS of around 50. Once the bot is enabled, the FPS dropped immediately to around 20 only, which often resulted in death of the snake due to the lag.

My computer was able to run 3 instances of bots in 3 separate windows at the same time without much issue when using version 0.9.3, but now it's struggling to even run one at version 0.9.6.

I understand that with the addition of new features, the code is bound to get more complicated and as a result more resource intensive. But I think this is a little too much that it's now affecting the performance of the bot.

I have downgraded back to v0.9.3 and it's running fine, so I suppose this rules out the server as the reason for the lag.

Can you test the latest version ?

[dingyang1988]

Testing it out now. Will update soon.
By the way, I think I may have found out the reason that causes the bug in #177, and posted a video demonstrating the bug.

Hi, is the latest version renamed to Slither.io-bot A*, version 0.9.3?
I cant enable the bot in this latest version, debugging console showing this error message:
VM220:445 Uncaught ReferenceError: collisionGrid is not defined

[ErmiyaEskandary]

Are you sure ? Works here for me

[ErmiyaEskandary]

Disable other scripts please...

[OthorWight]

This is the only script i have installed. I am getting the same error when trying to enable the bot.
Here is a section of the errors.

i can't start bots. When i press "T" then console log show this:
VM46071:445 Uncaught ReferenceError: collisionGrid is not defined

[ErmiyaEskandary]

Ah - found the issue.

[ErmiyaEskandary]

Can you test now with the latest version ? Should be fixed

[dingyang1988]

Still seeing the same error message. Is installation of the bot still the same? Just using bot.user.js? Or do I have to install the other files as well?

[ErmiyaEskandary]

bot.meta.user.js

[dingyang1988]

Doesn't work.
I think the bot isn't even loaded.

All I get is this in the console.

VM8332:53Syntax error @ "Slither.io-bot A*"!

I don't even see the bot HUD at all.

[ErmiyaEskandary]

Can you test now with the latest version ?

[ErmiyaEskandary]

Confirmed working.

[ErmiyaEskandary]

What about lag and performance ?

[dingyang1988]

Bot works now. Will report back on performance soon.

[dingyang1988]

Wow! The current version is freaking awesome! I'm mightily impressed! I'm gaining mass very fast.

Performance wise, I think it's better now. The FPS took quite a hit when grid debugging is enabled, but when disabled it's quite ok.

So from now on all installation with be done with bot.meta.user.js? What's the difference between these files?

[dingyang1988]

But seems to be crashing into sides of snakes quite often, even when not accelerating. Hmm...

[dingyang1988]

FPS drops quite a bit when the scene gets a little busy.. When bot is disabled in that scene, FPS stays at 40+, but dropped to around high 20s to low 30s when bot is enabled.

But compared to previous version of bots with just primitive functions, I think I can live with that... :smile:

Kudos to the developer team!

[joetex]

There are many settings (performance and smartness) that will be configurable in the near future. The different systems that run the bot are all new, so it took a bit of time to get them to a stable state. Now that we can implement new behaviors easily, we should be able to bring a smarter bot much quicker.

[ErmiyaEskandary]

We also are just using bot.meta.user.js - hot loads files and it is the file to install. :+1:
Kudos to the community ! :)

[ErmiyaEskandary]

Should be fixed now as we have changed systems... Feedback ?

[dingyang1988]

I guess we can consider this case closed?
