no, there arent any other things using a different way to lock the player, everytime i need to lock the player i use onpara
i should probably change onpara to just lockplayer to make it more clear for anyone reading it, it kinda evolved from one simple time i wanted to lock the player to multiple uses over time. i'll put in the updated code, thanks a lot i should also take more heed to wich var is triggered when and in what order.

wasn't trying to dunk on you or anything

no worries, i know my code is questionable at best :') i tinker around until i get the result i want and then i move on to the next thing so a lot could be done a lot more efficiënt and reliable probably but if it works, it works i guess

Is there a way to check if the floor is moving that a sprite is sitting on? I feel like there should be. Or maybe I should just check if the sprite is moving on its x or y axis after it should have stopped moving.

How you check will be different depending on whether the sector is actually moving, or whether there is a conveyer belt, which is texture panning plus a simulated movement effect.

[VGames]

I’m referring to the floor in Spin Cycle. How do I make an actor detect if it’s on the floor that’s spinning around in that giant room?

[Reaper_Man]

Without loading up the map I can't confirm, but I'm pretty positive the floors in Spin Cycle are conveyors, rather than actual "rotating sectors". There are a couple of game events that capture moving sectors, EVENT_MOVESECTOR and EVENT_MOVEEFFECTORS, but you'd have to test if either of these are triggered by conveyors. My instinct says no, because MOVESECTOR is for actual moving sectors (IE subway cars), and MOVEEFFECTORS is for vertical movement of elevators and doors.

Assuming neither of these events work, what I'd do is loop through sprofstat STAT_EFFECTOR to fine the SEs, check their tags to see if they match the conveyor tag number, then check if THISACTOR is in the same sector, and if so then you'll have confirmed it's on the conveyor. You may need to check other properties than .lotag, such as .xvel or .extra, as tags and other information gets applied in a way the engine understands on map load.

[oasiz]

It's a rotated sector.

Doing a conveyor would require tons of splits in order to align the texture's firstwall in a convincing way to make it look like it's spinning.

[VGames]

So what Reaper man said wouldn’t work?

Also conveyors tend to offset the sprites a bit, so after a few loops (well, I imagine in Spin Cycle it would take more than just a few loops due to how wide it is) they would end up stuck on the sides.

[oasiz]

Each sector movement effect is essentially just a macro at source level for wall movement in unison, the concept of "moving sectors" doesn't exactly exist.
When a sector is moved, rotated, etc.. sprites are also iterated on the same tick.

This extends to things like doors, rotating cogs, sliding doors, trains, etc..

Conveyors in turn simply change a sector's x/y panning in order to move a texture visually.
Sprites are handled like that as well.

I believe for conveyors it also uses x/y velocity on SE sprite (that gets reset) to get some distances that are used for sprite coordinates during interpolation itself.

If you were to take a snapshot of a map with moving sectors, you wouldn't be able to tell which bits are dynamic and which are static based on map data alone, that's where you need code.
(To be clear, there are some values left behind, if you're familiar with the effect itself then some sprite/sector struct members like .extra may store temp data that may give away it's state... always case by case basis)

No, they're just saying it's not a conveyor (my mistake). As it's a moving sector, I think EVENT_MOVESECTOR would capture it so I'd still try there first, and if you can't detect it in a way that makes sense, the for loop should still work as well.

Ok thanks I’ll se what I can do.

Oh one other question I’ve been meaning to ask and keep forgetting. Is there a way to track frame rate? I’d like to be able to check if it’s dropped below a certain amount like 30 frames or something. Just wondering

Yeah there is literally a predefined read-only framerate gamevar.

I was going to suggest having the sprites check for the presence of an SE0 in their sector, and then do whatever it is you want them to do if that comes back positive. But that's not enough because the SE0 has a hitag channel and the rotating can be off or on.

If it's the _movement_ that is the issue, you can write code that resets the coords of the sprites that would work independently of the cause of the movement, so you wouldn't need to detect the sector movement at all. If you are trying to keep the sprites in place, you would probably also need to lock down their visible coords in EVENT_ANIMATESPRITES (in addition to their actual coords), because otherwise they will appear to shake as the game moves them and then their actor code resets them 30 times per second.

If you ever do want to detect the presence of SEs in a sector, or any other kinds of sprites for that matter, here are a couple of useful references:

https://wiki.eduke32.../Headspritestat

https://wiki.eduke32.com/wiki/Statnum

You can set up a loop that traverses a linked list of sprites sharing a statnum, which is way more efficient than looping through all sprites. You could also loop through sprites in the sector, depending on your needs (see headspritesect)

Is there any way to force the Nightvision goggles to turn on and off without the player having to press the button? I wanted to make the nightvision goggles turn on when the sector you are in has a very low shade value and turn off when the sector is more lit up. I tried making a new night vision effect when the player presses the nightvision button by cancelling out the original usenightvision event and setting up some variables to handle all the effects but changing the palette to 3 only makes the screen green and doesn't make the enemies light up like the original night vision effect does. Any ideas or is this impossible?

Well first of all I would set heat_on to 1 in the player struct

https://wiki.eduke32.com/wiki/Heat_on

I don't think that changes the gamepalette though so you would probably have to do that as well. However setting that struct probably takes care of the enemies/items not lighting up

ah ok maybe that's what I was missing. Also am I supposed to be using the setgamepalette command to change palettes?

[Reaper_Man]

Doing a quick test, it seems like the issue is forcing heat_on without any available heat_amount. If you check or set non-zero heat_amount before forcing heat_on to 1, enemies light up as expected. Otherwise if it's 0, the gamepal changes to 2 so everything visibly turns green, but the actual night vision logic doesn't fire and enemies don't glow.

Side note, setgamepalette is deprecated and no longer required, you can change the gamepal via player[].palette directly now.

Is using a global var for general calcs safe as long as the define/get/function/set are back to back?

[Danukem]

lllllllllllllll, on 20 November 2022 - 12:43 PM, said:

Yes. And they don't have to be back to back, you just need to make sure that nothing is changing the global var in between your uses unbeknownst to you. The main thing to be wary of is spawning stuff, since that fires off events that you may have code on which potentially changes the global var.

[Reaper_Man]

In a word: Yes.

If you have a series of math commands run on a gamevar, the value of that gamevar will not unexpectedly change between commands even if the gamevar is reused elsewhere. CON commands are instructions executed in sequence order, so any use of or command using that gamevar before or after the block of code you're looking at won't effect it.

CON will always execute in the order that it's written, meaning that code that is written earlier in sequence will always execute before any other code later on down the line, whether in the same file or files loaded after it. The caveat here is code processing in game events, and without going into a really in-depth and kind of confusing explanation, keep in mind that events always execute in a specific order, and code within those events processes following the same sequential execution.

The execution of code and setting of data will also be dependent on the quasi-random execution order of a sprite's ID. Sprites will process their code individually in order of their sprite ID, so if you have 2 of the same actors which run the same code and both check for or set a gamevar's value, and the actor doing the checking happens to execute before the actor doing the setting because it was assigned a lower sprite ID, it won't be until the next gametic when the checker will "see" the value the setter set.

edit: lol

[VGames]

Is there any way to mess around with the Pig Recon Vehicle and how it spawns the PigCop when it crashes? There isn't any code in the CON files for this vehicle unlike the Pig Tank so I figured its hardcoded. Would I need to create an entirely new Pig Recon enemy?

[lllllllllllllll]

I think you can use event_EGS to modify the spawned actor. Something like

ifactor PIGCOP
ifspawnedby RECON

[Reaper_Man]

Yup, you can capture the spawn in several different events and alter the spawned actor that way. EVENT_EGS would work, that captures sprites spawned during gameplay. I tend to prefer EVENT_SPAWN to modify actors at spawn time, as it's more generic and will effect ones placed in a map as well as spawns at runtime.

[lllllllllllllll]

You'll be able to spoof a spawn chance in the same way. The chance to killit will be the chance not to spawn (and need to add -1 to total enemy count)

[VGames]

Oh ok yeah. I didn’t even think of going through the pigcop and checking if it was spawned by the recon. I’ve added 2 new pigcop variants and I only want the tank and the recon to spawn the original pigcop. But since the original pigcop has a chance to spawn one of the new pigcops and then get removed when it’s spawned sometimes one of the 2 new pigcop variants gets spawned instead when the tank or recon are destroyed. Thanks for the tip. This will help. I’ll have the pigcop spawned by the recon spawn my pigcop clone and remove itself which will then allow the pigcop clone to immediately turn into the original pigcop.

[Reaper_Man]

Instead of spawning and killing, you can use cactor to simply change which actor type the current actor is.

Is there a way to trigger a lotag via CON?

The reactor sprite pretty much works perfectly as a hidden trigger but it has a minimum radius of electrocuting the player instead of being contained to its sector and it also has hardcoded explosion damage that too has a minimum radius.
Placing the reactor where it can't see the player leaves it asleep and misses the explosion cue. Placing it in places where it can "see" the player sometimes doesn't wake it up in time for the cue.
There didn't seem to be any effectors that could activate things via explosion. The cracks and barrels are limited to other explosions or chaining cracks.

The thing on Reactors stopping rotaters would be cool too if it's possible.



The specific problem I ran into is explodable sectors do not block player Use in the spot that the hole opens up and 'fixing' that requires an activator or masterswitch to fire after it explodes.
