Lua AddHook for an Object

[ParaToxic]

Hey guys after a long break I want to create a new little game and learn a bit about scripting in lua. I want to create a 2D HUD entitie with a script that for example draws "Press the F key to..." if I collide with a Collider.

But I realized that I cant use the AddHook function inside of an object. How can I use drawing functions like DrawText in the objects script ??

 

Thanks

In your object script there should be a PostRender function

 

 

function Script:PostRender(context)

App.context:SetBlendMode(Blend.Alpha)
App.context:SetColor(0,1,0,1.0)
App.context:DrawText("Value: "..self.val, 100, 100)
App.context:SetBlendMode(Blend.Solid)

end

@josk I think you can just use the passed in variable 'context'. self.context and context would be different variables where if the context variable doesn't work then it's a bug.

So you can, learn something new every day. Thanks.

App.context:SetBlendMode(Blend.Alpha)
App.context:SetColor(0,1,0,1.0)
App.context:DrawText("Value: "..self.val, 100, 100)
App.context:SetBlendMode(Blend.Solid)

end

Keep in mind that App.context might not exist, if the script is running in a C++ program. So it's best to just use the function argument context.
