To detect if there is a collision among two sprites, it is possible to use the method hitTestObject( DisplayObject ) this way:
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;
}
}
}
It seems that there is a bug in version 1.2.2 of openfl-native, This is causing a compilation error when compiling for the Android platform and using Linux as a host.
The error is displayed as following.
-compile:

The solution consists on upgrading openfl-native to version 1.3.0:
haxelib update openfl-native

I am experimenting with OpenFL. Very fast and powerful when developing Flash apps.
