== Introduction ==

The launcher sign, similar to the [[TrainCarts/Signs/Station|station]] sign, can launch trains and make them reach a certain speed. The distance over which the train slows down/speeds up and the direction to launch can all be specified. Launching at a speed of 0 will slowly put the train to a complete halt, similar to how stations stop trains. Note that the speed is not locked after launching is completed: you can still push the train around or stop it entirely.

== Syntax ==

{{sign|[train]|launch 10|0.4|continue}}

=== First line ===

There is no difference between using ''[cart]'' or ''[train]''. [[TrainCarts/Signs#Remote Control|Remote control]] can also be used in combination with this sign.

=== Second line ===

''launch'' or ''launcher'', followed up by the launch configuration. Launching can be done over a set distance, a set time, or at a constant acceleration. The launch function can be configured as [https://en.wikipedia.org/wiki/Linear_function linear] or [https://en.wikipedia.org/wiki/B%C3%A9zier_curve bezier]. A bezier curve will accelerate slower towards the beginning and end of the launch.

=== Third line ===

The speed to launch at. If left empty, it will launch at the speed specified in the configuration (''launchForce''). To put the train to a complete halt, use 0.

Absolute speeds use a positive or zero number with no sign; to launch the train to a speed of 1.25 blocks per tick (25 blocks per second, or 90 km/h), use "1.25". Relative speeds require a sign even when positive; to launch the train to a speed 0.5 higher than it was before, write "+0.5"; to decrease the speed by 0.5, write "-0.5".

When only a value is specified, the unit is blocks/tick. For all other supported units, see [[TrainCarts/Velocity]]

=== Fourth line ===

Optionally you can specify the [[TrainCarts/Signs/Direction|direction]] to launch here. The default parameter, if blank, is "continue" – it will launch the train in the same direction from which it came.
