The only possible way a NPE could be thrown at that line is that the variable "animations" is null. What aazimon was asking: where do you assign the "animations" variable?

I thought
1  
animation = new Animation(true);//runR

is 'assigning' the 'variable'?

animations

This is why it is not a good idea to have two variables so closely spelled Wink
