After returning to play a tiny bit of SSBB this morning, I just had a playertype idea.
A Brawl player type.
Or a smash brothers playertype, whatever.
Basically, you are completely invincible.
Almost.
You can be killed by:
>Fall damage
>Onplayertouch > Player > Kill events
When you take damage, it adds a percentage to a percentage meter, and you get knocked back.
The higher the percentage, the more the knockback is amplified.
So:
Damage of weapon x Damage% (Going up to 999%, or 9.99 in the code) = Total knockback
It would be an interesting thing to see. If I explained it badly, play a Smash Brothers game.
