Computer Vision nodes

Classic computer vision: templates, masks, contours, shapes, blobs.

Image Detection

cv.image_detectionexec

Searches for one template image inside the window.

In: Window:HWND, Image:String, Threshold:Float, Use ROI:Bool, ROI X/Y/W/H:Int

Out: Found:Bool, Pos:Vec2, Count:Int, Confidence:Float, Result:DetectionResult

Image is the path to a template, Threshold typically 0.7 — 0.95.

Image Detection(Image=play.png) → If(Found) → Mouse Move And Click(Pos).

Multiple Image Detection

cv.multiple_image_detectionexec

Searches several templates and returns the first match.

In: Window:HWND, Image A/B/...:String, Threshold:Float, Process Scale:Float

Out: Found, Pos, Count, Confidence, Result

Add more Image inputs from the inspector.

Search play.png or continue.png in one block.

Multi Template Detection

cv.template_multiexec

Finds multiple matches of one template.

In: Window:HWND, Image:String, Threshold:Float, NMS:Float, Process Scale:Float

Out: Found, Pos, Count, Confidence, Result

Use when the screen can contain many copies of the same object.

Find all identical resources on the map.

RGB Pixel Detection

cv.rgb_pixelexec

Checks the colour of a pixel at a given position.

In: Window:HWND, Sample Pos:Vec2, RGB:String, Tolerance:Int

Out: Found, Pos, Count, Confidence, Result

RGB in the form `255,255,255`.

Check if the button turned green.

RGB Color Mask

cv.rgb_maskexec

Finds regions inside an RGB range.

In: Window:HWND, Mask Low RGB:String, Mask High RGB:String, Min Area:Int, Use ROI:Bool, ROI X/Y/W/H:Int

Out: Found, Pos, Count, Confidence, Result

Set lower / upper RGB bounds and a minimum area.

Find green objects on the minimap.

HSV Mask Detection

cv.hsv_maskexec

Finds regions inside an HSV range.

In: Window:HWND, HSV Low:String, HSV High:String, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

HSV is more stable than RGB across lighting changes.

HSV Low=0,80,80; HSV High=10,255,255 for red objects.

Contour Detection

cv.contoursexec

Finds thresholded contours.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

Best for simple high-contrast objects.

Find large UI element contours.

Shape Object Detection

cv.shape_objectsexec

Finds objects by contour shape.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

When the object stands out by shape.

Find a diamond-shaped marker.

Circle Detection

cv.circlesexec

Finds circles via the Hough transform.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

For round icons / markers.

Find a round target indicator.

Line Detection

cv.linesexec

Finds line segments.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

For UIs with strong horizontal / vertical bars.

Detect a progress bar appearance.

Edge Detection

cv.edgesexec

Finds edge contours.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

For objects with a noticeable edge.

Find the silhouette of a UI frame.

Bright Blob Detection

cv.bright_blobsexec

Finds bright connected regions.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

For glowing icons / dots.

Find a bright loot marker.

Dark Blob Detection

cv.dark_blobsexec

Finds dark connected regions.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

For dark blobs / markers on a light background.

Find a dark icon on a light map.

Object Detection (Shapes)

cv.object_shapesexec

CV object detection by shape.

In: Window:HWND, Min Area:Int

Out: Found, Pos, Count, Confidence, Result

Shape-based detection without a trained model.

Find an object by its geometric form.

Multi Detection

cv.multi_detectionexec

Runs detection across a list of templates and returns one combined result.

In: Window:HWND, Images:String, Process Scale:Float

Out: Results:DetectionResult, Count:Int

Pro. Images holds a runtime-supported list / description of images.

Check a set of UI icons in one pass.

Bar Percent

cv.bar_percentexec

Reads the fill percentage of a colour bar (HP bar, mana bar, cast bar) by scanning along its length.

In: Window:HWND, Rect X/Y/W/H:Int, Bar Color:String, Tolerance:Int, Orientation:String

Out: Percent:Float, Found:Bool

Bar Percent for HP → Compare < 30 → drink potion.

Ignore Object

cv.ignore_objectexec

Add a rectangle to a "don't detect me" list — classic detection nodes will skip this area until it's cleared.

In: Rect X/Y/W/H:Int

Out: exec Out

Add an area over your own UI to Ignore Object.

Clear Ignore Objects

cv.clear_ignore_objectsexec

Empty the ignore list.

In: —

Out: exec Out

Reset ignore list at the start of a new phase.

waitForObject

cv.wait_for_objectexec

Loops until a chosen thing appears in the window (or a timeout runs out).

In: Window:HWND, Image:String, Threshold:Float, Timeout ms:Int, Poll ms:Int

Out: Found:Bool, Pos:Vec2, Timed Out:Bool

waitForObject(loading_done.png, 10000) → next stage.
