This Expression 2 extension adds functions for collision detection and a new collision data type.
List of functions:
| Function | Description |
|---|---|
runOnCollision(entity ent, number activate) |
If set to 1, the chip will run when the specified entity collides with anything. |
number=collideClk() |
Returns 1 if the chip execution was caused by a collision. |
collision=getCollision() |
Returns the collision data from the last collision. |
entity=xcl:hitEntity() |
Returns the other collision entity. |
entity=xcl:ourEntity() |
Returns the collision entity. |
vector=xcl:hitPos() |
Returns the collision position. |
vector=xcl:ourOldVel() |
Returns the entity's velocity before the collision. |
vector=xcl:theirOldVel() |
Returns the other entity's velocity before the collision. |
vector=xcl:ourNewVel() |
Returns the entity's velocity after the collision. |
vector=xcl:theirNewVel() |
Returns the other entity's velocity after the collision. |
vector=xcl:ourOldAngularVel() |
Returns the entity's angular velocity before the collision. |
vector=xcl:theirOldAngularVel() |
Returns the other entity's angular velocity before the collision. |
vector=xcl:hitNormal() |
Returns the normal of the surface that hit the other entity. |
vector=xcl:hitSpeed() |
Returns the speed at which the impact happened. |
number=xcl:delta() |
Returns the time since the last collision with the other entity. |
number=xcl:speed() |
Returns the speed of the entity before the collision. |
table=xcl:toTable() |
Returns the collision data as a table. |
