Enemy Actor which increases and decreases its size (loop)

I want a smooth transition between a min and max value so that the enemy actor is able to expand and shrink (it's non-moving, just an obstacle)

Then, because multiple scaling will distort an image, you will need to keep the original image in a field; plus, you will need an int field to "time" the phases of expanding and shrinking. The value of the timer field can both regulate the speed and direction of change (expanding or shrinking). Always create a new image by copying the original image and then scale it to some new value. Basic codes would be:

Make a button that is affected by the state of another actor in the game

By 20silvan, with no replies.

so I'm trying to make a pokemon like game for my programming class and I need help with this, I want to make it so based on the health of the other pokemon the attack will do different amount of damage/lower the other pokemon's health even further so in the case that I attack and then attack again I won't only be able to set the pokemon's health to only 2 options, I have 3, full health, half health, and low health, I need help so I can set the image to low health when I choose an attack and the enemy is at half health it won't just set it to half again and just sets it to low because the enemy's health is already half, thanks for any possible help :)

File too big

By Heet_Patel, with 1 reply.
Replied to by Agent40, over 8 years ago:

As far as I know, Greenfoot doesn't update a Scenario because a file is too big. My current project is 110MB and I know people who have 600 and 900MB projects. The only thing I could assume from this would be to say that maybe the folder in which the scenario is saved has become corrupted and is reverting itself every time you make a save.

How do i show a health bar on an enemy?

I was wondering whether it was possible for an enemy to have a health bar attached to its image so that it follows it around screen?

Have each enemy create its own health bar and use (override) the addedToWorld method so that they can add the bar into the world. Have each enemy control the value and the position of its own health bar. You can add an act method to the health bar to remove itself from the world when zeroed. The enemy can remove itself when its health bar is found not to be in the world.

raising speed by score

I have a counter class to calculate the score. How to increase the number of enemy when the score reaches a multiple of 15?

Currently, you are creating an enemy after every 150 act steps. To increase the spawn rate, you would lower that number. If the score is to be what determines how much to lower that number, then you would need to subtract some expression of the score from it. You would need to consider what multiple of (score/15) to lessen it by. What value you choose will effect the game duration as well as what possible maximum score may be achieved.
