Propulsion animations

[cpdef]

Describe the feature you'd like Add some animations for the different propulsions, like wheels, tracks so that they look like they are moving. For example the wheels should rotate. Also if the droid stands, the animation should stop

Describe why do you think it is needed looks good

Images Here you can find the images for the drives, which should be animated:

It will require changes to code -> event-driven should be expanded to propulsions.

[bjorn-ali-goransson]

So propulsions are non-animated currently?

[MaNGusT-]

Currently, only buildings and bodies are able to use even-driven animation.

[cpdef]

Ok that sounds more hard to do then expected, but maybe only to me, because I'am not so familiar to the code until now. Any ideas where we could start adding the event-driven animations to propulsions? Maybe the same should be done with weapons to?

I did a POC for this just now: https://github.com/bjorn-ali-goransson/warzone2100/tree/bjorn-ali-goransson/animate-propulsion

There are two types of animation, texture animation and transformation animation (dunno what else to call it). That fork does only the transformation based animation, which is essentially the wrong kind, but was more difficult to implement so textures should be much easier.

Transformation based animation propulsions presents the following challenge, when to start the animation? And when to stop it? And at what speed? So I guess we'll hold on to that one until time comes. No doubt real animated tracks would look better than texture animations. But, baby steps...

I'll try to do the texture animation next.

If i understand MaNGusT right, it isn't currently possible to stop them. Or could you do it?

[bjorn-ali-goransson]

I believe it's not so hard. But to keep track of the current frame, especially throttled by movement speed, over time, is a challenge. Luckily the tracks won't have to be gracefully animated, they just need to "go brrr"

[bjorn-ali-goransson]

It works! And it was easier than the transformations based animation, just as I suspected!

Fork for that modification: https://github.com/bjorn-ali-goransson/warzone2100/tree/bjorn-ali-goransson/animate-propulsion-texture

We now need a texture for moving tracks. Perhaps we can get by with 2 frames, just alternating the colors of the tracks?

I'm thinking we can duplicate the contents of this red square and modify the PIE files accordingly. Maybe even make a new texture page...

@MaNGusT- what do you think? Would you be up to the task?

Forgot the new youtube link, where I link the animation speed to the unit speed:

I have my own to-do list in ARmod like from here to Mars. Also, I don't want to bother myself updating classic models but If you'll have success with the code committed, we could add such animation to ARmod in future releases. If you want to update classic models, you should better ask @Berg53

[bjorn-ali-goransson]

OK, just implemented this with some amateur pixel pushing.
