Need help with pickable crates

[Suomis]

Hi!

 

I'm quite a newbie with LE, but I've gone through all the non-lua-tutorials. I'm making a map which I try to use all the basic features in to learn their proper uses. I'm currently struggling with making a pickable crate. It falls through the floor every time I set it's mass to anything but 0 and I can't seem to get it to collide with the player either.

 

The crate is crate_small.mdl expanded to 300% size with physics set as Rigid body and collision as Prop. So far the only script attached is impactnoise.lua.

 

The floor beneath is a standard box with no scripts. It's set as Rigid body and Scene with a mass of 0. It's also a nav obstacle and the material used is greygrid.mat.

 

What I would want the crate to do, is for it to be located somewhere in the scene so the player has to pick it up and use it to get onto the ramp and to the control panel. Thus, I need it to collide with the player and environment and it needs to be pickable.

 

I have 3 screenshots attached:

Sieppaa1.png = picture of the scene with the crate located where it needs to be lifted by the player. Also includes physics of crate.

 

Sieppaa2.png = Scripts of the crate

 

Sieppaa3.png = The floor's physics

 

There might be some brainfart on my end since I'm new, but I can't seem to figure it out. Any help will be appreciated. Thanks in advance!

Just drag the prefab into the scene, found in the prefabs folder, and it will work.

Why doesn't the model have a box physics shape on it when I open it in the model viewer? What did you do different with the prefab to get that shape?

[Josh]

This was actually created before that system was even in place. The prefab has a setting to use a box around the object.

Just drag the prefab into the scene, found in the prefabs folder, and it will work.

 

Thanks! Now that you say it, it's the obvious thing to do, but for some reason it didn't even cross my mind to use the prefab instead of the model.

Your other option, moving forward with other things, is to open the mdl (dbl click it) and in the model viewer add physics box to it and save. Then you can drag it in and it'll work right.

[Josh]

Yeah, I think in the future we're going to eliminate the separate "Prefabs" directory and store them with the model, since they are almost always just based on one model.

I guess you'd have to weigh if that makes things easier to understand for users vs removing flexibility, because it may remove more advanced use cases.
