[15.13] [Rseding91] LuaSurface.get_trains(nil) errors

[Choumiko]

Using

Code: Select all

/c criteria = {surface = 'nauvis', force=nil} game.surfaces[criteria.surface].get_trains(criteria.force)
--or even
/c game.surfaces.nauvis.get_trains(nil)

results in "Error: Given force is not valid"

On the other hand

Code: Select all

/c criteria = {surface = 'nauvis', force=nil} game.surfaces[criteria.surface].find_entities_filtered(criteria)

works fine.

Both functions state that force is an optional parameter.

Expected behaviour: LuaSurface.get_trains(nil) should work by returning the trains of all forces.

[Rseding91]

You're passing "nil" in which is not a valid force. Pass nothing and it will work as you want.
