[SOLVED] Script_ Obstacle react differently to different attack types

Glitch · Oct 29, 2018

Hi guys, I have began my foray into scripting, I have no experience in programming other then Excel formulas, so even though I have an understanding of the logical steps in variable interaction I am unable as yet to write my own scripts in Openbor. I could really use some help.

I have a drum obstacle that I need to react differently based on the attack type that has hit it.

If it is hit by:

attack1 or attack2: (normal attacks)
fall down and roll a little (depending on direction of attack), remain in floor in a idle2 position being vulnerable to all attacks, all attacks would then make it roll a little more (depending on direction of attack)

attack3 to attack 6: (hard attacks)
get damaged and fall down being damaged (depending on direction of attack), remain on floor in damaged state vulnerable too all attacks, all attacks will not move it in anyway

attack7: (shoot attack)
play explode animation

attack8: (player use/interact animation)
would play an attack animation (0 damage) that would then make player kneel/crouch to hide using drum as cover

I have researched the many different scripts available on the forum, so many that can do so much, however I am unable to understand scripting enough to modify them.

I have tried with some success in regards to Ilu’s obstacle pain and facing script (
[http://www.chronocrash.com/forum/index.php?topic=3973.msg54825#msg54825), which is the base for what I require. However there is the ’’react differently based on the attack type that has hit it’’ problem which I can not solve.

Any help and/or suggestions would be greatly appreciated.

Below are the current drum obstacle text files, and the image files:

Ilu's Facingpain script, tried to modify it to my needs, I removed a line that checks entity is in idle animation, so that now it will work in all animations. Pretty sure it isn't right:

// Force obstacles to execute a different custom animations when taking hit plus based on which side the hit comes from.
// Douglas Baldan / O Ilusionista - 2018.07.28
// www.brazilmugenteam.com
void actual_main()
{
void self = getlocalvar("self"); // Get the caller
{
void opp = getentityproperty(self,"opponent"); // Gets who is attacking it
int direction = getentityproperty(opp,"direction"); // Gets opponent facing
if(direction == 1)performattack(self,openborconstant("ANI_FOLLOW1")); //Is entity facing right?
if(direction == 0)performattack(self,openborconstant("ANI_FOLLOW2")); //Is entity facing left?
}
}

Glitch · Oct 29, 2018

Currently it is working as follows:

Any attack makes it fall and roll a little (depending on attacker direction), it then remains on floor allowing it to be attacked by any attack again and then roll a little (depending on attacker direction).
Should the attack kill it in one hit then it will play death animation (explode)

Just need to get it to react to different attack types differently.

Also there is a glitch?, the drum can only be grabbed in rolled on floor idle position and not on stand up idle position??? When thrown it falls and rolls a little however sometimes after landing it rolls back towards the player (wrong roll direction)

DCurrent · Oct 29, 2018

Obstacles have default behavior regardless of the attack type. This is both for backwards compatability and memory saving. If you want more dynamic behavior you either have to script it or use a different type of entity for that object.

O Ilusionista · Oct 29, 2018

You would need to add a attack type check:

Code:

    int Type = getlocalvar("attacktype");// Get attack type
    if(Type == openborconstant("ATK_NORMAL2")){// if hit by attack2
 *INSERT YOUR LOGIC HERE*
    }

Noted well @Damon, I think I will go the script route.

Aha! so that is how to get the attack type variable. Thank you Ilu

I will insert this in the script and try it out tomorrow

I have read somewhere of this change type via in file script, easier than creating actual script file. Never knew how to do it until now, thank you Bloodbane

Some questions though:

I assume that even though enemies will be hostile to NPC, they will not be hostile and wont attack the drum, because in spawn frame it is an NPC for a 1/100th of second delay, is this correct?

Beside attacking it to make it roll and remain for more rolling, will I be able grab the drum and throw making it play a roll animation and then remain in on floor in another idle to be attacked for more rolling?

Will try it out as well, already have a drum NPC type from a previous try, will add the in file scripts and hopefully it will do all that i require.

Sorry for the questions, I have no experience with script. I hope this type change via script instills all the properties of an NPC in the drum

Glitch · Oct 30, 2018

It's is working 98% perfectly, thank you guys. I used Bloodbane's suggestion of change type via in file script.

Only one problem is that it cannot be grabbed in normal standing idle, any suggestions as to why? Or how to make it grabbable?

I will share the drum obstacle with different reactions to different attacks here for anyone to use if they interested. It adds more interaction, immersion, and change of gameplay

O Ilusionista · Oct 30, 2018

Nice trick, BB. I wasnt aware that some behaviour are inherited when the type changes.

O Ilusionista said:

Not just some, quite a few actually. This can get a bit confusing to explain, but I'll do my best.

Part 1.

Internally, OpenBOR sets up a series of flags and logic routines when a model is loaded based on what type it is. In turn those are passed on to entities as they are spawned from the model. In other words, a specific set of behaviors is given to the entity when it first spawns. Most of these routines don't bother to verify the type of entity they belong to. Why would they? It would be a waste of resources 99.99% of the time. And since all changing Type does is alter the Type flag itself, the entity's behavior isn't changed much at all. You'd have to alter a whole crap ton of other stuff too.

That's why you can spawn in an NPC, change it to an Obstacle type, and it will still behave like an NPC .

Part 2.

OK, those same routines I just talked about - that logic does verify the type of other entities. That's how an Enemy type knows to attack Players and ignore other Enemies, just as an example. So while altering the Type flag may not change an entity's own basic behavior, it does change how other entities will behave toward it.

Thus, why changing an NPC to an Obstacle type will cause other entities to treat it like an Obstacle.

Put those two parts together, and that's how/why Bloodbane's trick works.

O Ilusionista · Oct 30, 2018

Ah, makes sense. Thanks for the explanation.

Glitch · Oct 31, 2018

Thanks for the explanation @DC, this trick is amazing. So much can be done with it @Ilu, I noticed it can make the obstacle a moving platform which can actually be controlled with attacks by player, like the controllable movable platform in Mario3 (picture below) or even a soccer ball that can be kicked around differently, even a movable obstacle to block paths/open paths/jump higher etc...

;D so many possibilities

edit: makes a funny ''skateboard'' that character stands on/rides, character kicks/pushes on ground (attacks skateboard) to move forward

just like in real life, the more you kick/push the more you maintain the high speed and not slow down

I am using BB's trick in my game to make movable obstacles to block paths/open paths/jump higher etc and to be used as cover when being shot at or just to rest against lol.

Just one question though guys, why can I not grab the obstacle while it is in idle position, how can I make it grabbable?

O Ilusionista · Oct 31, 2018

Check it your player has candamage obstacle and hostile obstacle.
But the last one can make you grab obstacles even when you don't want to (like in some moves). You can control this using grabforce or even by script.

Glitch · Oct 31, 2018

Player has "candamage enemy obstacle npc", hostile was not in header, I added "hostile obstacle" but still not able to grab entity.
I even removed platform in idle, but still not able to grab, simply passing through entity.

Thanks for suggesting it Ilu, how would I go about forcing grab with script?

O Ilusionista · Oct 31, 2018

I think its a side effect of changing the type. About the script, I was talking about to avoid the grab, not forcing it.
If you need a script to interact with obstacles, you can use ONBLOCKOSCRIPT, which triggers when you are blocked by an obstacle.

Glitch · Nov 1, 2018

O Ilusionista said:

I thought so as well, so I removed the in file scripts. The entity was left as a normal walking NPC entity, still I was not able to grab it, simply passed through. So that means it is not a side effect of the script...hmm...will try to to get the entity able to be grabbed without it having the change types scripts, then upon hopeful success will add scripts back and see what happens.

O Ilusionista said:

Will search on forum for the ONBLOCKOSCRIPT, hopefully I will be able to decipher it :-X lol and use it to my needs.

[SOLVED] Script_ Obstacle react differently to different attack types
