Grenades(Hand Grenades, Flares, Smoke and More)
-----------------------------------------------------------------------

[Important Note - Update 1-16-2023]
This mod only works properly in Single Player. Some features do not work in multiplayer and full multiplayer support is planned but I really can't say when I will be able to finish it.

At very least, the mod should not crash dedicated servers and has limited functionality.

Multiplayer: If dropped from inventory, smoke grenades and flares will act as they should. Hand Grenades will not explode or cause damage, Proximity Mines will explode but will not cause damage , Flashbang Grenades and EMP Grenades will play particles but may not affect anything in the world.

Multiplayer: Grenades and flares can not be thrown by the player. If you attempt to do so, the grenade or flare will spawn in at your location and play it's particles for the local player, but will not have any physics or gravity, can not be moved and can not be picked up, destroyed or otherwise interacted with. It will likely not be visible to other players and any physical effects such as damage from explosions, player being stunned by flash bang grenades etc will not happen on the server. The grenade or flare will despawn when it's particle effect is done.


Update 4/29/2022: This mod currently does not work properly with the updated Water Mod.

[General Description]
This mod adds player hand grenades,colored smoke grenades, colored emergency flares, oxford commas, and a few other throwable items to Space Engineers.

[Important Note]
Grenades, flares, smoke grenades, etc. are treated as floating objects in the game. They are automatically removed from the world when their time is up. For best results, increase floating object count in game settings. The more objects allowed the better depending on your system abilities. Also please remember that if there are too many floating objects, the game with remove some of them. Also the game's trash removal system may remove them if they are too far away.


[Update 1/24/2021]
- Improved Flare Effects.

[Update 7/04/2020]
Fixed errors from update 1.194
The mod is working again with a few bugs. EMP Grenades and Flash Bang grenades particle effects are incorrectly playing and have lost their sounds.
Smoke particles transparency doesn't work well with the new weather effects
I will continue to look into this but at least the majority of it is working.

Right now development of mod in Multiplayer is on hold. I wasn't able to get it working properly. You can try it but expect there to be major bugs.


[Update 4/06/2019]
- Improved Particles.
- Particles are now affected by light.
- Added a random rotation to grenade trajectory.
- Reduced light flare range to 15m.
- Added "Practice Grenade" (Ctl + U)

[Update 3/09/2019]
- Fixed Particles not working. (Broken in 1.189)

[Update 2/06/2019]
- Improved throwing of grenades from moving character. Characters velocity is now added to the grenade.
(Smoke particles will still look strange on fast moving ships due to the way the particle system works.)
- Limited rate of fire to once per second to reduce grenade spamming.


[Update 12/05/2018]

Increased flare burn time to 5 minutes.
Updated icon textures thanks to Stollie. A few are still missing but most of them are there.
Improved colored smoke particles.
Improved Flashbang particle.
Removed extra message showing.

--------------------

This mod is in development and may have a few bugs or issues.
Please rate and comment, I have limited time to mod and the more popular a mod is, the more likely I am to improve it.

Controls
-----------

There are several different colors of flare grenades and smoke grenades.
The mod will use the first of each type of grenade found in your inventory (i.e if red smoke grenade is found before, green smoke grenade, the red one will be used). Re-order grenades in your inventory to change tytpes.

To throw an explosive hand grenade, press CTL + G.

To throw a Flash Bang grenade, press CTL + N.

To throw a Flare grenade, press CTL + F.

To throw a Smoke grenade, press CTL + T.

To throw an EMP grenade, press CTL + R.

To throw a Proximity Mine, press CTL + E.

To throw a Practice Grenade, press CTL + U.

Pressing Shift along with one of the above will cause the grenade to be lightly tossed instead of thrown.

Known Issues
-------------------

Multiplayer support is still in development.
Known Issue: In DS, grenades can not be thrown, grenades can not be picked up by players once thrown.
Damage does not occur in Multiplayer.

Grenades always destroy armor blocks if they are close enough regardless of the damage applied. This is not intended and is built into the ModAPI Explosions. Without writing my own explosion class, I can not fix this. I may get to that at some point but it is not officially planned.

There is a bug in Keen's code causing particles that should not be lit, to become lit between 30 and 80 meters from the camera. Particle lighting works between 0 and 30 meters, and works beyond 80 meters. Hopefully Keen will fix the root cause.

There are no animations.

There are no sounds for flares burning or grenades smoking.
There are explosion sounds. Explosions sounds are arcade sounds and not realistic sounds.

Explosive grenades will no longer explode when being spawned into the world with the F10 menu, but flares and other particle based grenades will play their effects. This will also happen if they are dropped from inventory or in a container that is destroyed. The best way to add grenades to your inventory is to spawn them into a container or make them in an assembler.

When thrown, an explosive grenade becomes a "Live Grenade", if a player picks up a live grenade or it is put into a container, it should still explode but does not. Live Grenades in inventory do nothing.(I've not yet implemented this functionality)

Grenades now disappear from the world once used. Also if there are used grenades in the world when saved, they will play their particle effects when the save is loaded so you probably don't want to leave a bunch laying around.

If you are in a cockpit, grenades can still be thrown but will be ejected straight up. Be careful if you are in a flight seat inside a large ship or you may end up tossing grenades on your head. This behavior will probably be changed in the future when a block version is added.

Also keep in mind that if you are in a cockpit, the F key will eject you from the cockpit so you won't be able to throw flares without leaving the cockpit.

Some of the icons may not match their items, Icons were added to help distinquish the grenade types and colors but they need work. If anyone cares make some icons I may add them.
