After spending about 24 hours the past 30 hours on my game making skills I finally managed to do it!
I got my characters to animate movements and attack on my iPhone, calculate the damage and show it on an enemy which also will flicker to show it's receiving damage :D
All of the above basically gets triggered when you choose to do a physical attack on an enemy.
So it's basically just 1 turn (WTF I know xD).
The hardest part was to actually show that my characters were doing something.
Now an artist can basically fill my placeholders and the result should be clear on screen right away without editing anything (maybe the time for each little animation).
Right now I have 12 image placeholders in a sprite sheet which has a character moving to the left, right, attacking, cast magic, use an item.
What's left now is a magic attack animation when choosing the option Magic and an animation for using an item on themselves/party.
If I can do that then I basically have my battle system complete and I can go on to make my levels and an artist can make my characters with their animations without interfering with each other.
I'm so relieved I managed to get it to work. It felt like trying to destroy a wall by smashing your head against the wall :d :p
