Hi Friends,
With the new V0.5.4 update there is a new base type property named "Constant update". If you find any of your animated objects, scripts and actions are not working, it will be due to this new property being set to false. Simple enable this and all dynamics will return to normal.
The reason for this property is that many game objects don't need to be processed by the main game update and in many cases there will be a performance boost by disabling this property.
We have uploaded a new version of the Invader project to its topic page link with this property enabled.
Thanks
