best 3D Collision behavior for Construct 3

3D Collision Behavior for Construct 3

Construct 3's built-in collision system only works on the XY plane — objects flying above each other still trigger collisions. 3D Collision fixes that by adding true 3D AABB detection including the Z axis.

How it works:

• Add the behavior to any object that should participate in 3D collisions
• Set Width, Height and Depth to match your object's actual size
• Assign a Group name (e.g. Player, Enemy, Bullet)
• Set Collide With Groups to specify which groups to check against
• Use Is colliding  condition in your Event Sheet and add Action, done

Features:

• Full 3D bounding box (AABB) collision detection
• Group-based filtering for performance and flexibility
• Works with any Sprite / 3D object
• Zero Event Sheet setup required — runs automatically every tick
• Offset X/Y/Z to fine-tune hitbox position independently from the object
