attempt to preform arithmetic on field "xvel" (a nil value)

[Omnikariz]

I'm getting this error in my player.lua, inside my player.physics(dt), and I'm not really sure how to fix this with the error.

Code: Select all

function player.physics(dt)
	player.x = player.x + player.xvel * dt
	player.y = player.y + player.yvel * dt
	player.xvel = player.xvel * (1 - math.min(dt*friction, 1))
end

I've gotten this error before and I really don't know at all what to do about it.

.LOVE For the game is attached, thanks in advance.

This error means that the variable player.xvel does not exist at the time when the corresponding line is executed. Add

Code: Select all

player.load()

to you love.load and the error is gone (you will get a different error then, because friction is not defined).

Yeah, thanks, shortly after posting this I found out the problems. Thanks anyway though.
