Phaser sprite vs. sprite collision

phaser-sprite-vs-sprite-collision.md

Results of collide(sprite1, sprite2) or overlap(sprite1, sprite2).

Body 1	Body 2	collide	overlap	embedded	touching.none	overlapX/Y	separation¹	acceleration¹
sprite.exists=false		false	false
enable=false		false	false
checkCollision.none=true		false	false
immovable=true		true	true		false	≠ 0	no	no
moves=false		true	true		false	≠ 0	yes	no²
bounce³ is 0		true	true		false	≠ 0	yes	no
delta⁴ is 0	delta⁴ is 0	true	true	true		≠ 0	no	no
[overlap > maxOverlap⁵]			true		false	≠ 0
[overlap > maxOverlap⁵]		false				0	no	no
[all other cases]		true	true		false	≠ 0	yes	yes

1. Separation and acceleration happen only via collide. Separation means Body 1 is moved outside Body 2. Acceleration means Body 1‘s velocity changes.
2. The body‘s velocity does change but there is no movement while body.moves=false.
3. body.bounce.x or body.bounce.y
4. body.deltaX() or body.deltaY()
5. maxOverlap is the sum of the two Bodies’ absolute deltas and OVERLAP_BIAS.
