This data pack allows the position of an entity or a position stored in scores to be compared to a ellipsoid area in Minecraft 1.14+
The calculation follows the formula x²/dx² + y²/dy² + z² + dz² <= 1.
All input numbers use a scaling factor of 10, the squared distance output can't be said to use proper distances in all situations but uses a scaling factor of 100.
To avoid an integer overflow during calculations, the system first detects the given position being outside a cuboid area following the sizes of the ellipsoid area. Being outside will result in an output distance of -1.
- Rotating the area without fully exchanging the axes
- Detecting the full hitbox of an entity intersecting with the ellipsoid area
- Scoreboard inputs to set up
All inputs are written into the
tdh_el:inputsobjective. List of fake players to set scores for:$center_x$center_y$center_z- Set the center position of the target area.
$dx$dy$dz- Set the size of the targeted area. The ellipsoid will expand towards each direction from the center position for the given delta values.
$x2$y2$z2- Only required and used to compare the area to a position previously stored in a score.
- Functions
tdh_el:detect_from_entity- Compares the position of the executing entity to the ellipsoid area defined by the input scores.
Stores a value of
1in the$result tdh_el.outputscore if the position is inside the area, else stores a value of0.
If the position was inside of the cuboid area that extends for as far as the delta values go from the center position, the$distance² tdh_el.outputscore is set to the square of the distance between the center position and the entity with a scaling factor of 100. Else, a value of-1is stored as the square of the distance.
- Compares the position of the executing entity to the ellipsoid area defined by the input scores.
Stores a value of
tdh_el:detect_from_scores- Has the same effect as the function
tdh_el:detect_from_entity, but instead of taking the position of the executing entity, it takes the position stored in the scoreboard values of$x2,$y2and$z2in the objectivetdh_el:inputs.
- Has the same effect as the function
tdh_el:entity_pos_to_center_input- Stores the current position of the executing entity as the center position of the ellipsoid area.
tdh_el:entity_pos_to_second_pos_input- Stores the current position of the executing entity as the position used by the function
tdh_el:detect_from_scoresinstead of the entity position.
- Stores the current position of the executing entity as the position used by the function
