Pushing a Monster

[BloodyAcid]

Is there a function that I can apply to my weapon so that I can push a monster? For example, I shoot a slider block that pushes an imp against a wall to kill it.

A simpler one would be shooting a ball that hits and kills the monster, but also tosses the corpse away.

or use A_RadiusThrust with a small radius

[BloodyAcid]

Thanks Ænima and Tichy.

I have one last question: Is there anything I can do to make a projectile increase in size as it travels? (Besides having separate sprites that grow increasingly larger)

[Ijon Tichy]

collision? no

you could see if A_SetScale is in for sprite resizing, but it probably isn't

[ZzZombo]

You can constantly spawn bigger projectiles.

Yeah, you can spawn a projectile for one second, make it kill itself then spawn another one in its place that is a bit bigger.

...And keep going like that.

It won't properly work because you'll need to transfer the properties of all previous projectiles, such as pitch or owner. There is really no perfect way of doing what he wants currently.

[Ænima]

It seems like all he wants to do is change the sprite scale, not the hitbox.

You either have to open Photoshop/Gimp or wait for A_SetScale to be backported.

[Ivan]

Since he put "besides having separate sprites that grow increasingly larger" I assumed he wanted to get them to have bigger hitboxes on the way as well. Eitherway, you need to wait for it. If it's going to make you feel better, I already made a request for that on bugtracker some time ago.

[ZzZombo]

It won't properly work because you'll need to transfer the properties of all previous projectiles, such as pitch or owner. There is really no perfect way of doing what he wants currently.

Can't you check things you are speaking about right before to speak? A_CustomMissile() with CMF_TRACKOWNER|CMF_AIMDIRECTION in flags and pitch parameter set to pitch Decorate property is used to properly spawn missiles in missiles.

[Ivan]

Then I suppose you have a working example. Care to show ?

[ZzZombo]

Naaah, havn't much time to do such useless things. All I said above is enough to do it youself.

[Ivan]

Naaah, havn't much time to do such useless things. All I said above is enough to do it youself.

So you say that's useless, that means helping people is useless. That means your posts in this thread and a couple others are useless. You should not even post then ... Great logic.

[XutaWoo]

A_CustomMissile can't be used to fire a projectile with the same pitch as a previous projectile, mostly because projectiles aren't actually given pitches.

You'll have to wait for some A_SpawnItemEx flags to be backported before you can use the 'actor shoots other actors' method.

[ZzZombo]

Did YOU checked things before saying them? I have a project which abuses this function to spawn a bunch of missiles and it workx just as well as I can drink.

[BloodyAcid]

Everything's waiting to be backported. Oh well, thanks for the replies. Guess it's time to add more sprites

I works as it should: missile CacoBomb spawns a bunch of smaller projectiles, what upon hitting an object will shot Cacoballs in reverse direction.

I did something like this before, it was just a projectile with A_RadiusThrust on it and no damage. Dunno if it'll work perfectly for you, push it'll push them.
