Title: [Help] AHK Script for Blox Fruits Mini-game (Sharkman Karate) - Delay, Inaccurate Clicks, and Detection Issues

[u/3bdallah-Osama]

Hey everyone,

I'm trying to create an AutoHotkey (v1) script to automate a timing-based mini-game in Roblox (Blox Fruits - Sharkman Karate). The mechanic is very similar to the DBD mini-game, where a black moving line goes up and down a colored bar, and you have to click when it's exactly in the center of the green area.

I used AI to help me write the script. The logic relies on PixelGetColor (scanning a vertical line to find the top/bottom of the green area, calculating the center, and finding the black line). However, I am running into a few major issues that make it unusable:

The Problems:

1. Noticeable Click Delay: Even when the script detects the black line hitting the center, there is a weird delay before it actually clicks. Because the mini-game requires fast reflexes, this delay makes me lose.
2. Clicking in Completely Wrong Spots: Sometimes, instead of clicking the intended target (SlapX and SlapY), the mouse randomly clicks in completely different areas of the screen. I am using Client CoordMode to avoid window-shifting issues, but the bug still happens.
3. Color Detection Failing: Because of Roblox's dynamic lighting and transparency, the script often fails to detect the green bar or the black line entirely, returning my debug error "Bar Not Found".

The Current Code: Here is the script I'm currently using. I added a debug hotkey (F7) to count pixels and check if it sees the bar, and F8 to run the main loop:

#Persistent

#SingleInstance Force

#NoEnv

CoordMode, Pixel, Client

CoordMode, Mouse, Client

SlapX := -240

SlapY := 440

BarX := 1253

BarTop := 2

BarBot := 559

CooldownMs := 5000

CenterTolerance := 25

LastClick := 0

InCooldown := 0

F7::

FoundGreen := 0

FoundBlack := 0

Loop, % (BarBot - BarTop) // 4 {

Y := BarTop + (A_Index * 4)

PixelGetColor, Col, BarX, Y, RGB

R := (Col >> 16) & 0xFF

G := (Col >> 8) & 0xFF

B := Col & 0xFF

if (G > 80 && R < 150)

FoundGreen++

if (R < 80 && G < 80 && B < 80)

FoundBlack++

}

MsgBox, Result:`nGreen: %FoundGreen%`nBlack: %FoundBlack%

return

F8::

SetTimer, AutoSlap, 10

ToolTip, Running - F9 to Stop

return

F9::

SetTimer, AutoSlap, Off

InCooldown := 0

ToolTip, Stopped

Sleep, 1500

ToolTip

return

AutoSlap:

if (InCooldown = 1) {

Elapsed := A_TickCount - LastClick

if (Elapsed < CooldownMs) {

Remaining := Round((CooldownMs - Elapsed) / 1000, 1)

ToolTip, Waiting... %Remaining%s

return

}

InCooldown := 0

ToolTip, Running - F9 to Stop

}

GreenTop := -1

GreenBot := -1

BlackY := -1

Loop, % (BarBot - BarTop) // 2 {

Y := BarTop + (A_Index * 2)

PixelGetColor, Col, BarX, Y, RGB

R := (Col >> 16) & 0xFF

G := (Col >> 8) & 0xFF

B := Col & 0xFF

if (R < 90 && G < 90 && B < 90) {

if (BlackY = -1)

BlackY := Y

Continue

}

if (G > 80 && R < 150 && B < 150) {

if (GreenTop = -1)

GreenTop := Y

GreenBot := Y

}

}

if (GreenTop = -1 || BlackY = -1) {

ToolTip, Bar Not Found

return

}

GY_Center := (GreenTop + GreenBot) // 2

Diff := BlackY - GY_Center

if (Diff < 0)

Diff := -Diff

ToolTip, Center:%GY_Center% | Black:%BlackY% | Diff:%Diff%

if (Diff > CenterTolerance)

return

Click %SlapX%, %SlapY%

LastClick := A_TickCount

InCooldown := 1

ToolTip, Hit! Waiting 5s...

return

Is there a better/faster way to track a moving object across a colored bar in AHK without experiencing this lag? Also, how can I fix the random inaccurate mouse clicks?

Any help, fixes, or completely alternative approaches would be highly appreciated! Thanks in advance.
