Any command to DISABLE Player movement when we USE something?

[Russell]

I've got an object on my game with a little tutorial showed when we interact with it. But as player, we can move around when the tutorial is active.

Is there any way to disable Player movement and Enable when i wan?

Thanks a lot!!

I'm thinking about create a Global variable like "ReadingSomething"  and a function on FPSPlayer.lua for change movementspeed when we are reading or not.

But i don't know how develop this with code, i'm looking over the net for examples, and not able to find anything. Anyway i'm looking the code of the rest *.LUA on Leadwerks to learn the syntax to do this...

You would probably just want to add a variable to the player script like this:
self.disableMovement = true

And then add an if statement around the code that handles player input..

Thank a lot Josh for your answer.

I understand what are you saying, but i don't know how write code in LUA...

I have a model (a switch) with 3 functions Script (ImageSwitch.lua). When we hit it, an image show centered on screen as i wanted. But I can walk and move away from the area with the image showed on screen. This is my code for show the image:

--------ImageSwitch.lua----------
Script.HudTexture=""--string "Name Texture"
local ShowedImage="No"

function Script:Start()
    texture = Texture:Load("Materials/MyMaterials/"..self.HudTexture..".tex")
    textureEmpty = Texture:Load("Materials/MyMaterials/EmptyTexture.tex")
end

function Script:Use()
    if ShowedImage=="Yes" then
        ShowedImage="No"
    else
        ShowedImage="Yes"
    end
end

function Script:PostRender(context)
    if ShowedImage=="Yes" then
        context:SetBlendMode(Blend.Alpha)
        context:DrawImage(texture,context:GetWidth()/2-texture:GetWidth()/2,context:GetHeight()/2-texture:GetHeight()/2,texture:GetWidth(),texture:GetHeight())
    end
    if ShowedImage=="No" then
        context:SetBlendMode(Blend.Alpha)
        context:DrawImage(textureEmpty,context:GetWidth()/2-textureEmpty:GetWidth()/2,context:GetHeight()/2-textureEmpty:GetHeight()/2,textureEmpty:GetWidth(),textureEmpty:GetHeight())
    end
end

------------------------

If I want our player to not be able to walk from place until the switch is turned off again, I have thought about putting a global variable to control it. But I don't know how to write the code to be able to change the "moveSpeed" of the FPSPlayer.lua when "ShowedImage" is YES in my ImageSwitch.lua

Thanks a lot for your answer.

If you open up the FPSPlayer script you can see that the player itself will be passed into the Use() function:

--Use the object, whatever it may be
usableentity.script:Use(self)

So you could add a value directly onto the player in your switch function:

function Script:Use(player)
    player.disablemove = true
    if ShowedImage=="Yes" then
        ShowedImage="No"
    else
        ShowedImage="Yes"
    end
end

And then disable the player input in the FPSPlayer script if this value is set to true:

if self.disablemove ~= true then
	if window:KeyDown(Key.W) then self.input[1]=self.input[1]+1 end
	if window:KeyDown(Key.S) then self.input[1]=self.input[1]-1 end
	if window:KeyDown(Key.D) then self.input[0]=self.input[0]+1 end
	if window:KeyDown(Key.A) then self.input[0]=self.input[0]-1 end
end

Thank you very much Josh!!!

Your code has been very useful to get exactly what I intended to do.

Many thanks.
