[0.7.1] Function switching of event

[rk84]

Giving new functions inside ontick -event for ontick -event leads to crash. Can be avoided by calling "game.onevent(defines.events.ontick, nil)" before giving new function.

Test1: never prints tock

Code: Select all

--test1.lua

game.onevent(defines.events.ontick, function(event) tick(event) end)

function tick()
	game.player.print("tick")
	game.onevent(defines.events.ontick, function(event) tack(event) end)
end

function tack()
	game.player.print("tack")
	game.onevent(defines.events.ontick, function(event) tock(event) end)
end

function tock()
	game.player.print("tock")
	game.onevent(defines.events.ontick, function(event) tick(event) end)
end

Test2: This one works, but if for example you remove nil in tack -function it will crash in 8-9. cycle. Might be bit random

Code: Select all

--test2.lua

game.onevent(defines.events.ontick, function(event) tick(event) end)

function tick()
	game.player.print("tick")
	game.onevent(defines.events.ontick, nil)
	game.onevent(defines.events.ontick, function(event) tack(event) end)
end

function tack()
	game.player.print("tack")
	game.onevent(defines.events.ontick, nil)
	game.onevent(defines.events.ontick, function(event) tock(event) end)
end

function tock()
	game.player.print("tock")
	game.onevent(defines.events.ontick, nil)
	game.onevent(defines.events.ontick, function(event) tick(event) end)
end
