Lua library:
TargetPractice
Starting with 0.9.21, this library provides a function to create an entire target practice mission which follows some basic properties.
Here is a brief description of the generated missions:
- The player will get a team with a single hedgehog.
- The team gets a single predefined weapon infinitely times.
- A fixed sequence of targets will spawn at predefined positions.
- When a target has been destroyed, the next target of the target sequence appears
- The mission ends successfully when all targets have been destroyed
- The mission ends unsuccessfully when the time runs out or the hedgehog dies
- When the mission ends, a score is awarded, based on the performance (hit targets, accuracy and remaining time) of the hedgehog. When not all targets are hit, there will be no accuracy and time bonuses.
If you want to create a more sophisticated training mission, use your own code instead. The main motivation to write this library was to reduce redundancy in existing target practice missions.
TargetPracticeMission(params)
This function sets up the
entire training mission and needs one argument:
params
.
params

targets
| The coordinates of where the targets will be spawned. It is a table containing tables containing coordinates of format
{ x=value, y=value }
. The targets will be spawned in the same order as specified the coordinate tables appear. There must be at least 1 target. |
