Hi Karl0z, nice work!
I like the "core" structure you've made, I already connected it with the building it's self and it works pretty good! Just don't forget to connect the "core" structure to the "ground polygon" so that the building won't fly away.

The reason the top is falling is because the brown polygons (the roof) on the sides are not marked as "no self collision". For example If you have 2 objects colliding with each other with the same collision group you have to mark them both as "no self collision" or make them defferent collision groups.

Also you can make some smaller parts of the building like some parts of the stairs or crosses - the same collision group and don't mark them as "no self collision" so that they will collide when the building gets destroyed just like in real life. Just make sure that the don't cross each other to prevent the collision when the building is just standing.

Also it's better to use the "grid tool" to be more precise, it's located at the right side of the main panel with "play" button.

Also it's better to press the "undo" button after every time you hit "play" to test the building, that way all the parts of the building will get back to it's original state and you will avoid the mess. You can make a "laser thingy" from my most recent Ostankino scene, it is located on the left side of the big texture polygon. when you hit "play" it instantly shoots a laser that tells you that the scene has been launched and if you want to get the building to it's original state you have to press the "undo" button as many times as it's needed untill the laser will disappear.
Also don't forget to mark the "brake" option in the axles properties to prevent them from spinning.

Hope this helps! 👍

Hey, Can i get permission to help you with this scene?

Hey Messiah, im sorry for the late response but, thanks for the tips! i will try to apply them on my scene, but i dont get what you mean with the "ground polygon", what do you mean with the ground polygon? Anyways, thanks again for the tips, also i have a tiny question that you kind of forgot to answer, so in the scene "The Spass Tower", i asked you how did you make those smoke explosions? they looks pretty cool and i want to implement them on some of my future scenes, i will credit you for the explosions, but if you dont wanna tell its ok, im pretty comfortable with using tracers as smoke XD

By the "ground polygon" I basically mean the ground that the building is standing on, in the toolbox it's actually called the "plane tool".
When you start a scene from the scratch it consists only of the background and this plane tool that we use as a ground for any objects.
So just like with every building there is a foundation to it that goes under the ground. To imitate that foundation you have to basically stick your core structure to the ground with some more pillars and axles so that the building would be connected to the ground and won't fly away.
Just don't forget to remove all collision layers from the pillars that go under the ground so that it won't collide with the ground it's self.

About the explosions - I spent lots of time making it because I am bad at scripting and don't know how to make a "spawnable bomb". Unfortunately there is no way I can explain how I did it in order for you to be able to replicate it, because it would sound very confusing, but if you want I can upload it in a seperate scene, maybe it would actually be usefull for other people too.
But to be clear it's not exactly a bomb with smoke, it's an object consisting of several polygons with tracers that imitate the destruction of a concrete or a brick wall that falls appart into dust.
Anyway let me know if you want me to upload it.

ohh ok, thanks for explaining! also you can upload it in a separate scene if you want, i called them "smoke explosions" because i really did not know how to call them, anyways it would be really useful to give more realism to my little buildings i make! i really like those dust particles you made!

FINALLY THE TOP IS FINISHED

I MEAN FIXED

is this still WIP lol

yes

:bangwall:
how to make that emoji
