Making the ai move backwards after it's hit

Ok, I generally have it working, but sometimes when I'm really close to the enemy it'll go over me and not backwards(opposite x/y of it's direction).

This doesn't happen often, but it's a bug that's really annoying me... sometimes it will happen allot.

Code(Not this is from the step event, all variables are set up in the scripts)

Code: [Select]

if global.hit=true {
depth=-y
if place_free(x+lengthdir_x(8,direction),y+lengthdir_y(8,direction))
if place_free(x+lengthdir_x(8,direction),y+lengthdir_y(8,direction))
x=min(max(x,0),room_width)
y=min(max(y,0),room_height)
if (place_meeting(x,y,atc_mask)){speed=2;direction=point_direction(global.herox,global.heroy,x,y)
hero_is="l"
}}
global.hit_timer+=1
if global.hit_timer>12 {
can_move=false;
speed=0
instance_change(ai_goku,0)
global.hit_timer=0
global.hit=false
}
Note it's generally the same in all 4 objects, but only hero_is is actually changed.

Here's a demo as well, it might help with the problem visually.

Z is to do Melee attacks
X is to do Ki based attacks(only ki blast as of now, haven't coded any others yet, or implemented)

Also, since it's an action battle system(ABS) it will move in diagonal movements depending on where you strike the ai, that's one of my favorite things about GM, Pixel Perferctness!

Just so you know, the link is screwed up, you have to copy/paste it. I'm downloading the example now, I'll get back to you if I come up with something :]

EDIT: Actually, I can't seem to recreate the problem. I did find a small movement bug. If you move diagonally one way, and then move in the opposite direction the hero's sprite doesn't update and it looks like you're moonwalking. That's an easy fix though. I'll keep trying for the original problem.

EDITEDIT: Also there seems to be a random 0 in the top left corner of the map that changes colors along with the damage color. It seems to be counting down something whenever I shoot the beam thing. I don't know if that's supposed to be there or not

Personally I wouldn't reverse its direction for this, that seems a very shoddy way of doing it. When the enemy is hit you should take a vector between its position and the position of the weapon that hit it, then increase the position by the inverse of the vector each frame afterwards. Produces a perfect backwards movement.

Hmm, I've seen this done before. I think it was in an example or tutorial in a zelda engine. If it is can you direct me to it?

I don't use GM so I'm afraid not, I'm sure someone else here will be able to direct you though.

This could be useful. It's a very good engine, credit Goodnight

The only problem with that engine, as it's very close to mine and even when I change the speed to .5 it's still to fast.
