Strange lag?

By Unicus, with 7 replies.
Last reply by Unicus, over 11 years ago:

The lag is gone now; If I change the code to the second one, it keeps removing and adding the object gameover, so I guess I'll leave it as it is. It no longer fills my memory, so it's ok. I just published the game (beta version still), so if you want to take a look, you can find it here: http://www.greenfoot.org/scenarios/11355

Add checks for that boolean. If that boolean is true, don't let certain things happen (like take a hit). For example to make it so enemy fire doesn't harm your Hero. First make your boolean shieldActive static.

With a 'lifespan' of 400, maybe about 7 to 8 seconds, if your scenario is running at normal speeds (about midway on the speed slider).

ok, if i want to implement a shield powerup, can i just use setImage a new image if a fireball collects it and then the shield starfighter can just eat the enemies bullet, if so, what could the code look like

It would make more sense to have a separate actor for the shield. The starfighter object should have a field to reference it when it is active (null when not). If the collision code

Last reply by danpost, over 11 years ago:

You will probably need to use 'new java.util.Vector(2.2, 3.1)' (if you are using the java.util.Vector class); or, 'new Vector(2.2, 3.1)' if you are using your own Vector class.

Let us break it down: We are using a for loop to iterates through a collection of object. This collection is created by calling 'getWorld().getObjects(Pins.class)'. 'getWorld()' (Actor class method) returns the world that the actor, referred to by 'this', is in. 'getObjects' (World class method) returns a list of objects of the specified class (Pins.class) Each iteration will set 'obj' to a different Pins object that is in the world. The 'obj' variable holds a reference to an Object type object. '(Pins) obj' on line 3 casts the referenced object as a type of Pins object. It is then ass

Last reply by mcGreen, over 11 years ago:

That did the trick! Indeed there was a tag on it. Somehow its now too large to upload it. Edit: Tried again and it suddenly works... strange. Anyway, only thing I need now are enemies who can run around from left to right.. I would like them to lets say, walk 3m in one direction, then stop, and then walk 3m in the other direction. Other than that the game is pretty much finished Another question: Why do the Sprites glitch like that?
