# Jump Module
This includes:
* Standard jumping
* Variable jump height
* Multiple jumps
* Coyote time
* Jump buffering
* Better gravity
* Apex hang
The module is designed to create responsive, forgiving, and polished platformer movement.
***
## Component
```
JumpModule
```
***
## Responsibilities
The Jump Module controls:
* Jump force
* Airborne movement feel
* Jump timing assistance
* Multiple jumps
* Falling behavior
* Apex jump smoothing
It works together with:
* Rigidbody2D
* CollisionDetector
* PlayerInputHandler
***
## Inspector Settings
## Jump
### Is Enabled
Enables or disables the Jump Module.
| Setting | Description |
| ---------- | -------------------------- |
| Is Enabled | Enables jump functionality |
Useful for:
* Testing
* Temporary mechanic disabling
* Custom gameplay states
***
## Jump Force
Controls the upward jump velocity.
| Setting | Description |
| ---------- | -------------------- |
| Jump Force | Strength of the jump |
Higher values create taller jumps.
Recommended Range:
```
10 – 18
```
***
## Max Jump Count
Controls how many jumps the player can perform before touching the ground.
| Value | Result |
| ----- | ----------- |
| 1 | Single Jump |
| 2 | Double Jump |
| 3 | Triple Jump |
Recommended Range:
```
1 – 2
```
***
## Forgiveness
The Forgiveness section improves jump responsiveness and player comfort.
This includes:
* Coyote Time
* Jump Buffer
These systems help reduce missed jumps during fast gameplay.
***
## Coyote Time
Allows the player to jump shortly after leaving a platform.
This creates more forgiving platforming controls.
| Setting | Description |
| ----------- | -------------------------------------- |
| Coyote Time | Allowed jump time after leaving ground |
Recommended Range:
```
0.1 – 0.2
```
***
## Jump Buffer Time
Stores jump input slightly before landing.
This prevents missed jump inputs during fast gameplay.
| Setting | Description |
| ---------------- | ---------------------------- |
| Jump Buffer Time | Duration to store jump input |
Recommended Range:
```
0.1 – 0.2
```
***
## Variable Jump
Variable Jump Height allows players to control jump height by releasing the jump button early.
| Setting | Description |
| -------------------- | ----------------------------------------------- |
| Variable Jump Height | Enables shorter jumps when releasing jump early |
Enabled:
* Creates responsive jumps
* Allows precise platforming
* Improves movement control
Disabled:
* All jumps reach full height
***
## Better Gravity
Better Gravity improves airborne movement feel by adjusting gravity during falling.
This creates:
* Faster falling
* Snappier jumps
* Better platforming responsiveness
***
## Fall Multiplier
Controls additional gravity while falling.
| Setting | Description |
| --------------- | ------------------------------------ |
| Fall Multiplier | Extra gravity applied during falling |
Higher values:
* Increase fall speed
* Make jumps feel tighter
Lower values:
* Create floatier jumps
Recommended Range:
```
2 – 4
```
***
## Apex Hang
Apex Hang slightly slows gravity near the top of the jump.
This creates:
* Smoother jump arcs
* Better air control feel
* More polished platforming movement
***
## Use Apex Hang
Enables or disables Apex Hang behavior.
| Setting | Description |
| ------------- | ------------------------------ |
| Use Apex Hang | Enables apex gravity reduction |
***
## Apex Threshold
Controls how close the player must be to the jump apex before Apex Hang activates.
| Setting | Description |
| -------------- | -------------------------- |
| Apex Threshold | Apex detection sensitivity |
Lower values:
* Smaller apex window
Higher values:
* Longer apex duration
Recommended Range:
```
0.8 – 1.5
```
***
## Apex Gravity Multiplier
Controls gravity strength while Apex Hang is active.
| Setting | Description |
| ----------------------- | ------------------------------ |
| Apex Gravity Multiplier | Reduced gravity near jump apex |
Lower values:
* Floatier apex
* Longer hang time
Higher values:
* Faster apex movement
Recommended Range:
```
0.3 – 0.7
```
***
## Recommended Settings
## Responsive Platformer
| Setting | Value |
| ----------------------- | ----- |
| Jump Force | 12 |
| Max Jump Count | 2 |
| Coyote Time | 0.15 |
| Jump Buffer Time | 0.15 |
| Fall Multiplier | 2.5 |
| Apex Threshold | 1 |
| Apex Gravity Multiplier | 0.5 |
***
## Precision Platformer
| Setting | Value |
| ----------------------- | ----- |
| Jump Force | 10 |
| Max Jump Count | 1 |
| Coyote Time | 0.1 |
| Jump Buffer Time | 0.1 |
| Fall Multiplier | 3 |
| Apex Threshold | 0.8 |
| Apex Gravity Multiplier | 0.6 |
***
## Dependencies
Required Components:
* Rigidbody2D
* PlayerInputHandler
* CollisionDetector
***
## Notes
* Coyote Time and Jump Buffer greatly improve responsiveness
* Better Gravity creates tighter platforming movement
* Apex Hang helps create smoother jump arcs
* Variable Jump Height improves player control
* Proper ground check placement is important for reliable jump resets
***
## Common Setup Tips
* Increase Fall Multiplier for tighter movement
* Use Apex Hang for smoother jump feel
* Lower Apex Gravity Multiplier for floatier jumps
* Enable Variable Jump Height for precision platforming
* Combine Coyote Time and Jump Buffer for maximum responsiveness
