Authors and contributors to this experimental extension: D8H.

Warning

This is an extension made by a community member and it only got through a light review by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of fully reviewed extensions.

A terrain with hills where objects with the 3D physics behavior can stand.

A terrain can be built from:

an image file
noise function (open the project online)

3D height map

A terrain with hills in 3D.

Object actions

Update height map
Update the height map. This is done automatically at the end of every frame, but it can be used manually to avoid a 1-frame delay.

See parameters

Parameter 0: 👾 Object

Technical note: parameter 1 are internal parameters handled by GDevelop.

Load height map
Load a height map from an image file.

See parameters

Parameter 0: 👾 Object
Parameter 1 (imageResource): Image
Parameter 2 (🔢 Number): Image cropping offset on X
Parameter 3 (🔢 Number): Image cropping offset on Y

Technical note: parameter 4 are internal parameters handled by GDevelop.

Grid value
Change the field value at a grid index. The value is bewteen 0 and 1.

See parameters

Parameter 0: 👾 Object
Parameter 1: 🟰 Operator
Parameter 2 (🔢 Number): Value
Parameter 3 (🔢 Number): X grid index
Parameter 4 (🔢 Number): Y grid index

Technical note: parameter 5 are internal parameters handled by GDevelop.

Object conditions

Field point Z
Compare the field Z for a given position in the scene.

See parameters

Parameter 0: 👾 Object
Parameter 1: 🟰 Relational operator
Parameter 2 (🔢 Number): Value to compare
Parameter 3 (🔢 Number): X position in the scene
Parameter 4 (🔢 Number): Y position in the scene
