New Camera Shake Feature

[titi_son]

You can let the camera shake now

This feature is meant for tanks shooting big rockets, heavy running elephants or exploding buildings.Like this
Or if you want  to see it in an RTS here (when the tower dies)
Here is the syntax:

Code: [Select]

<skill>
<type value="move"/>
<name value="move_skill"/>
<ep-cost value="0"/>
<speed value="375"/>
<anim-speed value="240"/>
<animation path="models/warrior_walk.g3d"/>
<sound enabled="false"/>
<shake enabled="true" intensity="10" duration="40" start-time="0.5">
<self enabled="true" visible="true" in-camera-view="true" camera-distance-affected="true"/>
<team enabled="true" visible="true" in-camera-view="true" camera-distance-affected="true"/>
<enemy enabled="true" visible="false" in-camera-view="false" camera-distance-affected="true"/>
</shake>
</skill>
intensity=intensity
duration=duration in update frames (40 per second)
start-time=start time. works like in <sound>

self=options for the player
self=options for your allies (excluding you)
enemy=options for the opponent

visible=If visible is true the camera only shakes if the unit is visible (not hidden in fog-of-war). ( this is nearly useless for team and self but i am not sure what happens if you kill a not completed building or a unit with sight 0 )
in-camera-view=if true the camera only shakes if the unit is in the actual camera view (watch the video if you dont understand)
camera-distance-affected=the distance between the unit and the camera position is taken in consideration (watch the video if you dont understand)

Video showing the feature:


Should this be added to the glest wiki already or should i wait until this is included in a stable release?
(here it is shown for the stop skill, but works for all skills: https://docs.megaglest.org/XML/Skills#Stop)

I'm very excited to try this out!

Looks cool. I did notice in your video that shadows on the edge of the screen flicker (although I believe this is a long-outstanding camera issue and shaking merely demonstrates this issue -- not cause it).

Can you elaborate on how the intensity value works? I'm assuming it's related in some way to the distance the screen moves? Similarly, how does camera-distance-affected work?

Also, you're welcome to add it to the wiki immediately, but I think you should mention (until it's part of a stable release) which revision this was implemented in.

[titi_son]

i added it to wiki already, but only for stop skill because i dont have time now to add it to all skills. ( and i think the system that you have to add it to all skills is bad)
and yes the intensity thing is how much the camera shakes (how far its going left,right,up and down)

the camera-distance-affected is maybe better explained in wiki:

If camera-distance-affected is true the shake intensity is affected by the distance between the unit and the camera position

bigger distance between the unit and the camera -> smaller intensity

EDIT:
i found this while browsing the glest wiki:
https://docs.megaglest.org/GAE/Earthquake
is that a similar effect? and i thought i had a cool new idea

[tomreyn]

This is a nice effect, good job!

New lua commands to let the camera shake:

Let the Camera Shake (camera-distance-affected=false)
shakeCamera(int Intensity, int Duration)

Let the camera shake but camera-distance-affected=true (you need to give a unitID for that ofcourse)
shakeCameraOnUnit(int Intensity, int Duration, int UnitId)

[Ishmaru]

It would also be useful to have the shake effect on splash particles, eg Nukes exploding, powerful spells, etc.

I tried to implement it but its harder than i tought.This will take a while...
