How to check if a key is down in Lua?

[ddabrahim]

Hi, Sorry for the noob question but I really have no idea what am I doing wrong.

 

I would like to check Inside an object Lua script If a specified Key is pressed then play a specified animation of the object but I always get "then" expected near "(" or "("expectd near ' or argument expected near "(" error message and I have no idea what am I doing wrong. I was looking for the answer in the documentation and in other Lua scripts but I just can't get it to work.

 

This is the code I'm using

 

function Script:UpdateWorld()

if window:KeyDown(Key.W) then
self.entity:SetAnimationFrame(Time:GetCurrent()/50.0,1,self.walk)
end

end

 

Also tried many other ways such as

 

KeyDown(Key.W)
window:KeyDown(Key:W)
Window:KeyDown(Key:W)
KeyDown(Key:W) == true

 

But nothing works

 

Also tried using while loop instead of if statement but no luck.

 

I was also watching the Lua script video tutorials on youtube but it using Leadwerks v2.3 and looks like scripting worked differently in that version as even that way I can't get it to work.

 

I'm appreciate any help.

If inside an entity script you can do:

 

App.window:KeyDown(Key.A)

 

If inside App.lua

 

self.window:KeyDown(Key.a)

 

You were so close with many variations that you had

 

 

If you want to get caught up quickly on Lua for LE you can schedule some 1 on 1 training via the link in my sig. Each 1 hour session is only $10 and I go through all of this stuff. I explain all of this stuff and you'll understand Lua for LE at a more lower level and why these things are the way they are.
