Stages in Project DIVA can have several effects applied without having to animate them directly, and are driven with plain text files held in rom/stage_param:

== Coli ==
The simplest stage effect, '''Coli''' adds collision for physics in game. A '''Coli''' file can be applied to:

* A whole stage (simply by naming it coli_[stage].txt),
* A specific [[Mothead]] frame (with the _mhd[frame] suffix),

* Or to a specific performer (with the _p[number]_[frame] suffix)

A '''Coli''' file holds collision objects, with each object holding a value for:

|-
|Friction
|[value]
|Sets the [[wikipedia:Friction|friction]] applies to physics interacting with the object
|-
|pos.0.[X,Y,Z]
|[value]
|Sets the first point of the object in 3d space
|-
|pos.1.[X,Y,Z]
|[value]
|Sets the second point of the object in 3d space
|-
|Radius
|[value]
|Sets the radius of the object
|-

1 is disabled
2 is a ball
3 is a cylinder
4 is a plane

Project DIVA positions the object based on the pos.0 and pos.1 values, starting from pos,0, and stopping at pos.1.

'''Coli''' files also hold [https://github.com/search?q=repo%3Akorenkonder%2FReDIVA%20struct%20osage_ring_data%20%7B%20%20%20%20%20float_t%20rect_x%3B%20%20%20%20%20float_t%20rect_y%3B%20%20%20%20%20float_t%20rect_width%3B%20%20%20%20%20float_t%20rect_height%3B%20%20%20%20%20float_t%20ring_height%3B%20%20%20%20%20float_t%20out_height%3B%20%20%20%20%20bool%20init%3B%20%20%20%20%20OsageCollision%20coli_object%3B%20%20%20%20%20std%3A%3Avector%3CSkinParam%3A%3ACollisionParam%3E%20skp_root_coli%3B&type=code#:~:text=1886-,struct%20osage_ring_data%20%7B,-1887 Osage ring data], but goes unused in Project DIVA
