Para detectar si hay alguna colisión entre dos sprites se puede usar el método hitTestObject( DisplayObject ) de la siguiente manera:
if ( moving_left ) {
direction = DIRECTION_LEFT;
x = x - 1;
}
for (child in 1...parent.numChildren ) {
if ( Std.is(parent.getChildAt(child), Wall) ) {
if ( parent.getChildAt(child).hitTestObject (this) ) {
x = x + 1;
}
}
}
Parece que hay un bug en la version 1.2.2 de openfl-native que causa un error de compilación al compilar en linux para la plataforma Android.
El error es el siguiente.
-compile:

La solución ha consistido en actualizar la libreria openfl-native a la version 1.3.0
haxelib update openfl-native

Estoy haciendo algunos experimentos con OpenFL. Muy rápido y potente a la hora de desarrollar aplicaciones Flash.
