## Variables
*Variables are items in vpx you can set, adjust or call.*
| Call | Detail | Example |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------- |
| Name(string) | | |
| CapMaterial(string) | | |
| BaseMaterial(string) | | |
| SkirtMaterial(string) | | |
| Radius(float) | default=45.0 | |
| HeightScale (float) | default=90.0 | |
| Orientation(float) | | |
| RingDropOffset(float) | - An offset to influence the ring animation. The default move down limit is calculated by (HeightScale\*0.5) \* Table\_Scalez.
The final move down limit is calculated by RingDropOffset + (HeightScale\*0.5)\* Table\_Scalez.
For example: If the ring is moving too far down you have to try to set the RingDropOffset to -10. | |
| RingSpeed(float) | | |
| X(float) | X position | |
| Y(float) | Y position | |
| Surface(string) | | |
| Force(float) | | |
| Threshold(float) | | |
| Scatter(float) | | |
| TimerEnabled(bool) | | |
| TimerInterval(int) | set interval for triggering the timer (1 equals 1000 timer calls per second, 1000 equals 1 timer call per second, -1 makes it dependent on the FPS that a user can reach) | |
| UserValue(any) | can store any user defined value for re-use later-on | |
| CapVisible(bool) | default=true | |
| BaseVisible(bool) | default=true | |
| ReflectionEnabled(bool) | default=true | |
| EnableSkirtAnimation(bool) | default=true, en/disables the skirt animation of a bumper, for example if something external is triggering the bumper (i.e. no ball contact with the skirt) | |
| HasHitEvent(bool) | | |
| Collidable(bool) | | |
## Methods
*Methods are procedures or actions that you can fire in VPX.*
| Call | Detail | Example |
| --------- | ----------------------------------------------------------------------------------------- | ------- |
| PlayHit() | if called the bumper will play the hit animation without triggering the actual hit event. | |
## Events
| Event | Detail | Example |
| ------- | ------ | ------- |
| \_init | | |
| \_Timer | | |
| \_Hit | | |
```javascript
dispinterface IBumperEvents
{
properties:
methods:
[id(DISPID_GameEvents_Init)] void Init();
[id(DISPID_TimerEvents_Timer)] void Timer();
[id(DISPID_HitEvents_Hit)] void Hit();
}
