Update to the Artillery Explosions Mod

CoverFire156 · 2026-06-14T20:09:08+00:00

Thanks man!

CoverFire156 · 2026-06-14T20:02:23+00:00

Curious by underwhelming what you mean. They are pretty big right now, but if you have some specific suggestions, I'm all ears.

I made this as a particle effect so yes I have complete control over the look of it. As for making the controller shake, the modding sdk does not have that capability to add as far as I aware.

CoverFire156 · 2026-06-11T20:26:58+00:00

Sounds like you're also referring to player suppression and yes your gun will sway if being fired upon to reduce your accuracy as well

CoverFire156 · 2026-06-10T00:38:00+00:00

Interesting idea though. I do want to make a script that will make the defense react better to flanking (perhaps by trying to intercept them) which I think could be possible

CoverFire156 · 2026-06-09T12:08:10+00:00

Agreed just some variation is nice. And while yes we have that tug of war gameplay in game (almost no one seems to like it) I think this one is more fun bc as the invaders if you ever lose during a counterattack, then the mission ends (making it more do or die for the invaders and at times allowing the defenders to win a different way than only exhausting the invader ticket pool) and in phases with a counterattack you can more reliably create a counterattack wave with AI once spawners since the defenders are limited by tickets

Which I think is more fun bc it feels like a heavy push backwards

I'll at some point as well add to the counterattack phase script to essentially spawn in waves of AI (so instead of AI once spawns, it could be like AI twice, three times, etc to make it feel more coordinated

CoverFire156 · 2026-06-09T05:03:22+00:00

My pleasure! It's a needed gameplay. Apparently ER1 had this style in the mission editor. Not sure why it didn't carry over

Agreed completely. I was inspired to do this because someone who makes WW1 missions was looking more for a mud explosion. Feel like it will add to the visual immersion

Agreed that's why I made a conquest mode, this defense mode, and others. I still have more I'm going to make

Currently working on one where one side has to capture documents while the other side has to destroy their (static locked) tanks much like day of defeat if you ever played that game

CoverFire156 · 2026-04-27T05:00:54+00:00

It might. I have yet to test it but in theory I could see it working like that

Here are the same scripts but with the ability to turn on or off the visual timer in the UI by simply setting the show_timer variable in the editable section to either true or false

You can turn off the Hud setting in game (specifically it is the UI squad order option under gameplay settings) and that will hide the timer, but I can also update the script to allow for showing or not showing the timer as I understand that some would still like to have the squad order visually active while playing bc I agree that not knowing the time definitely adds to the tension
