"Knockback" on player hit

Hey there guys! I'm currently working on a pretty simple side scrolling fighting game (think Streets of Rage, Golden Axe, Castle Crashers etc) and i've hit a bit of a problem. The main character has three hit points, and each time you take damage i've managed to make the character fade out for a half second, but one thing I really wanted to do was to make it so once you took a hit, you jumped backwards a bit.

I did have something working with a weird bit of Player.X(-40) coding or something similar (I don't know the first thing about coding, haha) but it didn't work. I feel like i'm missing something simple, but any help would really be appreciated!

This is the current very barebones testing version that I threw together just to show a friend, but i'll put it here just in case it helps at all.

(arrow keys move, A is attack, all you can do at the moment is run, jump, kill, and die)

Thank you for any help you can give me!

should be quite straight forward....

player on collision with enemy

enemy.x > player.x

-->

player.x = player.x - 10

player.y = player.y - 10

I couldn't use your example file (says I need construct 1.8 and I only have 1.4) but I managed to get it working thanks to what you posted, so thank you!

Would you happen to know a way to make the player fly backwards, rather than just jumping instantly? I can use this just fine, but it would be useful to know for future reference :)

Well, upgrade to 1.8 then :D

Install it to a seperate folder if you don't like beta's

and ofcourse i can make him fly backwards instead:

Use time delta to maintain mobile performance

player.x = player.x - 100 * dt

player.y = player.y - 100 * dt

Well, upgrade to 1.8 then :D

Ah this is perfect! Thank you so much! :D

Exactly what i've been looking for. At the moment it was so easy to get chain hit to death, but with this hopefully it'll make it easier on the player. I'm a complete newbie to this all so i've just been trying random stuff that I feel should work but didn't, haha. Thanks again!

I tend to use player vector instead of directly setting player.X Also, you can use the flash behavior which may look a bit better than a fade...
