Push Out and Slide

Choose how overlaps are cleared. Minimum pushes along the single shortest direction (best for top-down). Separate clears the gravity axis before the cross axis, the stable land-then-touch-wall behaviour platformers expect.

Set the steepest surface, in degrees from flat, still counted as a floor (or ceiling) rather than a wall. Also limits how far a jump-thru can tilt and still catch a landing. Clamped to 0-90.

Choose where one-way platforms come from. None disables them. Jump-thru behavior uses every object with the built-in Jump-thru behavior. Custom uses the types added with Add jump-thru.

Set the maximum length of a single correction, in pixels. Set to 0 for no limit.

Choose whether contacts are labelled. Top-down treats every surface the same; Side-scrolling classifies each contact against the Up direction into floor, wall or ceiling.

Choose which objects count as walls: Custom uses the types added with Add solid, Solids uses every object with the built-in Solid behavior.

Set how the push-out correction is computed.

Set the gap kept between this object and solids after a push, in pixels.

Set the fraction of along-surface speed lost per resolution, from 0 (frictionless) to 1 (full stop). Values are clamped to that range.

Set whether the object slides along solid surfaces instead of stopping at them.

Set the maximum distance moved per step, in pixels. Movement is broken into steps no larger than this. Set to 0 to disable stepping.

Set which screen direction points away from gravity. Used in Side-scrolling style to tell a floor from a ceiling and to land objects on jump-thru platforms.

The current movement style key (top_down or side_scroller).

The current resolution mode key (minimum_push, axis_x, axis_y, nearest_open or swept).

Add an object type as a one-way platform for this object (used when Jump-thru source is Custom). The object can stand on instances of that type from above but pass through from below or the side.

Remove all object types from this object's jump-thru registry.

Stop treating an object type as a one-way platform for this object.

True if the given object type is registered as a one-way platform for this object.

The name of the registered jump-thru object type at the given 0-based index.

The number of object types currently registered as jump-thrus.

Search outward for the closest position where this object overlaps no solid, up to the given radius in pixels, and move it there. Triggers On ejected on success or On eject failed otherwise.

Run one resolution immediately, regardless of Resolve on tick. Triggers On pushed out if a correction is applied, or On became trapped if the object cannot be freed.

Set whether the behavior resolves.

Set whether the object is corrected automatically every tick after movement. Turn it off to push out only when you call the Resolve now action (for example for detection-only or discrete corrections).

True if the behavior is enabled.

True if this object currently overlaps at least one registered solid.

True if the last resolution preserved along-surface movement.

True if the last resolution left this object wedged against opposing solids.

Triggered when a resolution cannot free the object because it overlaps solids on opposing sides. OverlapCount reports how many solids it is wedged against.

Triggered after Eject to nearest open space succeeds. LastPushX and LastPushY give the offset from the original to the ejected position.

Triggered when Eject to nearest open space finds no open position within the radius. The object is left at its original position.

Triggered after a resolution applies a non-zero correction. The LastPush, SurfaceNormal, Slide and OverlapCount expressions describe the correction just applied.

Triggered for each step this object moves in, when stepping is enabled. Use it to make additional collision tests during fast movement. StepIndex and StepCount are available, and the object is at the current step's resolved position.

The length of the last correction, in pixels. 0 if the last resolution moved nothing.

The X distance of the last correction, in pixels.

The Y distance of the last correction, in pixels.

The number of distinct solids the object overlapped at the last resolution.

The length of the along-surface movement preserved at the last resolution, in pixels.

The X distance of the along-surface movement preserved at the last resolution, in pixels. 0 if no sliding occurred.

The Y distance of the along-surface movement preserved, in pixels.

The number of steps the object moves in during the current tick. 1 when stepping is disabled.

The index of the current step, starting at 0. Meaningful inside On step.

The X component of the unit surface normal the object was pushed off (the push-out direction). 0 if nothing moved.

The Y component of the unit surface normal. Use with SurfaceNormalX to detect which side a wall is on.

Add an object type as a solid for this object. Instances of that type will push this object out. Adding the same type twice has no effect.

Remove all object types from this object's solid registry.

Stop treating an object type as a solid for this object.

True if the given object type is registered as a solid for this object.

The name of the registered solid object type at the given 0-based index.

The number of object types currently registered as solids.

True if the last resolution pushed the object off a ceiling (a surface facing against the Up direction). Only meaningful in Side-scrolling movement style.

True if the last resolution pushed the object off a floor (a surface facing the Up direction). Only meaningful in Side-scrolling movement style.

True if the object is on a floor that is tilted (not level) - i.e. on floor with a non-zero slope angle. Only meaningful in Side-scrolling movement style.

True if the last resolution pushed the object off a wall (a surface too steep to be a floor or ceiling). Only meaningful in Side-scrolling movement style.

Triggered on the resolution where the object first gains a ceiling contact (it bumped its head). Side-scrolling movement style only.

Triggered on the resolution where the object first gains a wall contact. Read WallSide for which side the wall is on. Side-scrolling movement style only.

Triggered on the resolution where the object first gains a floor contact (it landed). Side-scrolling movement style only.

Triggered on the resolution where the object loses its floor contact (it walked off an edge or was lifted away). Side-scrolling movement style only.

The X component of the unit normal of the last floor contact (points away from the floor). 0 if no floor has been contacted.

The Y component of the unit normal of the last floor contact (points away from the floor). 0 if no floor has been contacted.

The signed angle of the current floor relative to level, in degrees. 0 on flat ground; positive when the floor tilts down toward the object's right. Meaningful while Is on floor is true.

How many resolutions have passed since the object was last on a floor. 0 while on the floor; grows once it leaves. Use it for coyote time (allow a jump for a few ticks after leaving a ledge). Only updates while Resolve on tick is on.

Which side a contacted wall is on, relative to the Up direction: -1 wall on the object's left, +1 wall on its right, 0 if not on a wall.
