Any way to change NOALERT flag during gameplay?
I was working on the silencer for my Quake II project and was trying to figure out the best way to make a weapon quieter and not alert monsters when the powerup is active. I found the "A_ChangeFlag" action function and figured I could use it to set the weapon's "NOALERT" flag to true when the powerup was active, but ZDoom tells me that the flag is unknown. I figured out an alternate means of achieving the silencer effect for most of the weapons, but it wont work for the machinegun, chaingun, and hyperblaster. For these, the only way I can think of to get the silencer effect is if I can change the NOALERT flag during game play. Can this be done, or do I need to use some hacky ACS to achive the desired effect?
Re: Any way to change NOALERT flag during gameplay?
I hope there is a better way to do this but the following might work:
Have all relevant weapons have the +NOALERT flag.
In the firing state sequence, have an inventory check that jumps past the next frame if true.
The next frame would call A_AlertMonsters.
The powerup would give the item that causes the inventory check to jump past the call to A_AlertMonsters.

That is exactly the workaround I used for the other weapons.
I've just completed a hacky and messy ACS implementation of the silencer for the machinegun by duplicating the machinegun with a silenced version and using ACS to switch to it when the silencer is active.
Spoiler:Unfortunately, I don't see how this will work with weapons with complex "HOLD" firing states like the chaingun.

Spoiler:Unless anyone knows of a better way to do this, I'm gonna do this for the chaingun and hyperblaster as well.

Frankly, the only viable option I see would be to add a PowerSilencer powerup that not only disables alerting monsters but also reduces the weapon's sounds (i.e. anything being played on CHAN_WEAPON.)

Well than, until such a feature can be implemented, I'll have to go with messy ACS. Its breakable and doesn't feel authentic to Quake II. Oh well, this sucks.Graf Zahl wrote:Frankly, the only viable option I see would be to add a PowerSilencer powerup that not only disables alerting monsters but also reduces the weapon's sounds (i.e. anything being played on CHAN_WEAPON.)

It would be a good idea to post about this in the Features Suggestion forum. At least then it would be part of the suggestions list.22alpha22 wrote:Well than, until such a feature can be implemented...
