Interactive bushes

[LanHikariDS]

So, I'm working on a standalone mod for the ZDoom engine, and one thing I'm working on is shrubbery. One thing I was hoping to do is have it react to what happens around it, so say a fireball goes through it, I want the grass to actually take damage from projectile attacks, without actually stopping the projectile. How can I go about doing this in the DECORATE definition?

[osjclatchford]

only way I can think of doing it would be to change the projectile behaviour as well, make it a ripper with a specific damagetype and give the shrub a corrsponding specific damage state. but then of course this will not just pass through said shrubs but also most other actors... tricky...

It'll take some time to set this up and require a small bit of dull effort, but the RipLevel property is probably what you want. Give your fireballs +RIPPER so they'll pass through the shrubbery unimpeded, but set its RipLevel to 1, perhaps. Then, every monster in your game, give them a RipLevelMin of 2. This will make it so that the fireballs will still be stopped by monsters. If you do want a projectile that rips through your monsters, set its RipLevel to 2, and it will rip through your monsters as usual.

You could have the bushes be vulnerable, but not shootable, and have the projectile call A_Explode with a very small radius and amount of damage every tic.

I wasn't aware of RipLevels, I'll give that a shot. Thanks guys!
