Enemies with multiple hit points

[SonicTheDalek]

I am making a new enemy called the Jetty-Syn Commander and I'm trying to give it two hitpoints like the Crawla Commander. I've tried setting the thing's health to 2 but it didn't work, can anyone help me with this?

Take note of the Crawla Commander; it also has two HP, but it works fine. The reason why is that its painstate tells it to flinch and be temporarily be invulnerable. That's what your Jetty-Syn needs, or else it will continually take damage when the player is attacking it.

I'm a novice at soccing, so I can't help you beyond that.

Chances are, your Jetty-Syn commander does actually have 2 HP, however, SRB2 handles HP in sortof a weird way. What's happening, is you collide with the enemy for more than two tics. The game reads that you've hit the enemy each time for every tic, causing the enemy to take more damage. Hence, it ultimately appears to have only one HP.

The solution, is to grant the enemy invulnerability for about a second after each hit. This is accomplished using A_SetObjectFlags, to set the... object's flags to be intangible and unaffected by gravity. Have about a second of delay, then call A_SetObjectFlags again to return the enemy's flags to normal.

Okay, now how exactly am I going to do that? Yeah, I know this requires additional states and such...

EDIT: I think I might experiment with something...

The wiki explains how to use A_SetObjectFlags. You need to make the first call in the object's painstate, and the second call in the state that the painstate leads to.

 

[SonicTheDalek]

Okay, so which flag should I use?

 

[Princess Plushima]

You shouldn't so much give it flags, as take away the MF_Shootable flag. That should get the effect you want.

 

[SonicTheDalek]

I'll try that.

EDIT: Tried it, and it didn't work. All it does is that it made the damn thing invincible! Did I do anything wrong? D:

Make sure to restore the flag after the invulnerability time is gone :P

 

[SonicTheDalek]

It still doesn't work. :\

 

[Princess Plushima]

You have to make sure it makes it to the state where it recovers it's vulnerability. Perhaps posting the contents of the SOC would be a good idea?

And I've already made it to be vulnerable again but it still gets killed in one hit. :\
