How to animate an object on impact?

by Dave Calabrese · in Torque Game Engine Advanced · 01/08/2008 (11:30 am) · 4 replies

I have a bit of foliage that I want to make rustle about whenever the player comes in contact with it. I've modeled up the foliage in MAX, gave it a quick 'rustle' animation, and popped it into my game. Now I'm trying to work out how to make this animation toggle whenever the player touches the object. I looked into using triggers, however those look like they only work on a client/server basis and I worry that could become expensive on the network (a player passes through 20 flowers, 20 network calls to all players - no good). So I don't need these to be network based, only local.

So my question, simply enough, is...

How do I make an object animate when the player comes in contact with it for the client only without getting the server involved?

Thanks,

OnCollision might work.

Why don't you just hook up PhysX, then the physics would handle this for you.

Mb: OnCollision works great, however also causes the object to bounce off the foliage rather than going through it.

Timothy: As awesome as that would be, PhysX isn't needed for this project (plus we're almost done, so adding PhysX at this point would be like baking a chocolate cake then while you're frosting it say, "Hey, let's make it vanilla!").

Seriously though, PhysX rocks and I can't wait to get to use it again. =)

I'm pretty sure using the ::onCollision function does not require you to enable physical collision. When our player is in contact with a weapon, onCollision is called and we use it to cause a script event that asks you if you want to pick up/swap said weapon, however it doesn't physically collide with the player or projectiles. But I haven't done anything with foliage and onCollision yet.
