No. I do not see anything here that might cause it, either. But, you can remove both lines 13 and 14 from the code.

Actor not in world? How can I fix it? :)

By Pe1per, with 4 replies.
Last reply by danpost, almost 11 years ago:

Since the player will "continuously" move and therefore "continuously" change the target location, the code will need to be placed in the act method of the enemies. If you "always" want them to turn toward the player, you should either use the World instance 'getObjects' method to get the player object or use the Actor instance 'getObjectsInRange' method using a very large range. Whichever way you go, make sure an object is returned in the list before trying to get the object and getting its location coordinates to turn toward.

Adding values of the array?

By elementa, with 1 reply.
Replied to by danpost, almost 11 years ago:

First thing, I do not see any place where you are actually changing the image. Line 2 assigns an image to the field 'displaytext' and line 5 continuously sets that image to the DisplayText object (the assignment of the image to the field is done once when the DisplayText object is created). Second thing, The image does not have to be continuously set in the act method. In fact, the DisplayText object does not have any actions to perform -- it just sits there in the world displaying its image, not doing anything in particular. The only time any changes occur to it is when a door is pressed,

That is a known issue and is believed to be a bug in JDK 7. As an alternative, you can use the following method which I created because of this issue: <Code Omitted>
