mouse direction

[IAsep-TrixI]

I was just wondering, how to check the mouse direction, because for my new game that Im working on in my spare time, he will look left and right when either A or D is pressed, but what I want him to do is that when my mouse is on the left or right from the middle of the screen and I click, it will face the direction of the mouse (not rotate just normal left and right direction)

Code: Select all

if mouse.x < screen.width / 2 then
    -- mouse is on the left half of the screen
else
    -- mouse is on the right half of the screen
end

Code: Select all

if mouse.x < screen.width / 2 then

I only want it to update when the mouse is clicked, should I do something like
If mouse is clicked then
if mouse.x < screen.width/2 then
blah blahb lah
end
end
?

It worked! It kinda didnt work right, so I tweaked it a bit to my likings so instead of screenWidth it is not player.x so that it goes left/right according to the players location
Thanks for the help guys!

It worked at first but when I started using tiled and the camera lib it started to mess up, do you know whats causing this?

[DaedalusYoung]

I've never used any libs, so I can only guess. The camera lib might change the mouse position value based on scale/translation/rotation.

Most likely the mouse is using screen coördinates, while the player is using world coördinates. There is most likely a function to convert between the two in the library; make sure both are using the same coördinate system.

I was doing

Code: Select all

if mouse.x > player.x then 
blah blah blah
end

it used the players coordinates to switch directions when the mouse is clicked
