Hola , A todos. Algunos ya sabran que es Imposible Superponer tu Aplicación sobre un Juego que trabaja con Direcx y que esta en
Pantalla Completa.
Bien Empecemos !
Introduccion : Es un Problema muy Común que cuando algún Programador en .Net , (Que haga Cheats) para juegos.
Cuando quiera superponer su Applicacion sobre el juego en pantalla completa no lo logre. ya que basicamente El Juego
"Secuestra la pantalla".
En este caso , hago este Post , para Compartir "Mi" solución a este Problema.
Cabe Resaltar que : - Los Juegos que Usan Como motor OPENGL, No tienen este Problema. Se puede superponer facilmente otra Applicacion sobre ellos.
- No todos Los juegos Direcx tienen este Problema, Por Ejemplo Operation7, WolfTeam, Swat4 ,Entre Otros...
- La mayoría de Juegos creados con Unity Tampoco tienen este Problema.
Entonces Empecemos...
Primero que todo Mi solución no fue Intentar Forzar de alguna manera la superposición. ya que no lo logre.
Quiero resaltar que hay un método que funciona,
pero No muy Practico a mi parecer. Basicamente tienes que Conectar con
EndScene .
Basicamente usando
SlimDX y
EasyHook, Aca un Breve tutorial :
[Tutorial] How to become an EndScene() hooker Por que no es muy Practico? , No lo es ya que Este metodo es facilmente Detectado por los AC (Anti-Cheats).
Solución : Bien mi Método , Fue una Solucion facil , Si no puedo Superponer sobre un Juego en pantalla Completa. Entonces :
- EMULARE EL MODO PANTALLA COMPLETA. Básicamente Hacemos esto : 1) Corremos Nuestro Juego en modo ventana, Algunos traen la opción en el Apartado de
Configuración - Video. En caso de que No traiga esta Opción , Tienes que Crear un Acceso Directo, Abrir las Propiedades del Acceso Directo y Colocar al final el
Parámetro :
"-window" De todos modos aquí dejo un Tutorial Sobre esto :
Play a Computer Game in Windowed Mode 2) Emulamos / Forzamos El modo FullScreen. Para Ello Hacemos : Paso 1 : Agregamos a Su Proyecto Las Clases
