Actions

🛟Add axes helper
The axis helper is added to the 3D object.
Note that it is added to the center point, not the origin point.

🧱Change blend mode
Change the blend mode of the 3D objects and all their children.
This affects all 3d objects that use the same material.

🔄️Change child angle
Changes the angle of the 3D object's child along the child’s local axes.
The names of the children must be checked in advance using the "🛟Output children hierarchy" action or a 3D modeling tool. This can also be used to rotate bones. Note that if a child is affected by a playing animation, it will override this change. In that case, please pause the animation.

😀Change morph target value
Change morph target values of 3D models.
The names of the morph target must be checked in advance using the "🛟Output morph target names" action or a 3D modeling tool. Note that if a morph target is affected by a playing animation, it will override this change. In that case, please pause the animation.

🥛Change opacity
Change the opacity of the 3D objects and all their children.

👤Change 3D shadow
Change the shadow settings of 3D objects.
If both "Cast Shadow" and "Receive Shadow" are enabled, striped patterns are likely to occur in the shadow.

🔄️Rotate child by angle
Rotate a child of the 3D objects along its local axes.
The names of the children must be checked in advance using the "🛟Output children hierarchy" action or a 3D modeling tool. This can also be used to rotate bones. Note that if a child is affected by a playing animation, it will override this change. In that case, please pause the animation.

🔄️Rotate child by speed
Rotate a child of the 3D objects along its local axes.
The names of the children must be checked in advance using the "🛟Output children hierarchy" action or a 3D modeling tool. This can also be used to rotate bones. Note that if a child is affected by a playing animation, it will override this change. In that case, please pause the animation.

🔜Linearly interpolate camera
Moves and/or rotates a 3D camera closer to another object’s position and rotation using linear and spherical linear interpolation.
Use the "factor" parameter to specify how much the camera should move and/or rotate (0 = no change, 0.5 = halfway, 1 = exact match).

🔜Linearly interpolate 3D object
Moves and/or rotates a 3D object closer to another object’s position and rotation using linear and spherical linear interpolation.
Use the "factor" parameter to specify how much the object should move and/or rotate (0 = no change, 0.5 = halfway, 1 = exact match).

🔜Linearly interpolate toward child of 3D object (Experimental)
Linearly interpolates 3D objects toward a child of another 3D object.
The names of the children must be checked in advance using the "🛟Output children hierarchy" action or a 3D modeling tool.

🔄️Local rotate by angle
Rotates the 3D object along its local axis.

🔄️Local rotate camera by angle
Rotates the camera along its local axis.

🔄️Local rotate camera by speed
Rotates the camera along its local axis.

🔄️Local rotate by speed
Rotates the 3D object along its local axis.

↔️Local translate camera by distance
Translates the camera along its local axis.

↔️Local translate camera by speed
Translates the camera along its local axis.

↔️Local translate by distance
Translates the 3D object along its local axis.

↔️Local translate by speed
Translates the 3D object along its local axis.

👀Look at 3D object
Rotates the 3D object so that its local +X direction points toward the target 3D object.

👀Look at position
Rotates the 3D object so that its local +X direction points toward a specified 3D position.

↗️Store normalized direction in variable
Stores the normalized direction vector of the 3D object in a variable.
The variable will be a structure variable with child variables x, y, and z. Note that the variable will only store the value of the first referenced 3D object.

🛟Output children hierarchy
Outputs the hierarchy of the 3D object's children to the console.
It is recommended to check in the developer tools console, where line breaks and indentation are displayed, rather than in GDevelop's debugger console. Use the following shortcut in the preview window to open the Developer Tools and select the Console tab: Ctrl + Shift + I (Cmd + Option + I).

🛟Output morph target names
Outputs the morph target names of the 3D object to the console.
It is recommended to check in the developer tools console, where line breaks and indentation are displayed, rather than in GDevelop's debugger console. Use the following shortcut in the preview window to open the Developer Tools and select the Console tab: Ctrl + Shift + I (Cmd + Option + I).

📚Overlap objects
Overlay the object on the 3D object.
⚠️ For objects to overlap correctly, they must be on a different layer than the 3D object. In the layer properties, the 'Default camera behavior' under 'Camera positioning' must be set to 'Keep top-left corner fixed'.

😀Reset morph targets
Sets all morph target values of the 3D object to 0.
Note that if a morph target is affected by a playing animation, it will override this change. In that case, please pause the animation.

Conditions

↔️Check the distance between two objects in 3D
Checks the distance between two objects (origin points) in 3D.

🥛Check opacity
Check the opacity of the 3D object, or the first opacity found among its children.
This condition can be used for non-3D objects as well, but in those cases the opacity is always compared as 255.

Expressions

Expression	Description
`A3F::DistanceObjects(object, object)`	Returns the distance between objects in 3D. (Distance between origin points)This expression always returns 0 when a 2D object is selected.
	👾 Object	Object
	👾 Object	Target Object
`A3F::Opacity(object)`	Returns the opacity of the 3D object, or the first opacity found among its children.
	👾 Object	Object

⚠️ 3D Lights are highly loaded.

Behavior actions

💡Change Light Color
Gradually changes the color of the 3D Light.
