Camera Collision

[MrIslomaniac]

What would be the easiest way to enable camera collision, just like the one in the editor?

Need this for a presentation on Tuesday =(, got to hurry up now

Hope you guys can help me

Thanks

[macklebee]

look at the Making A Spectator tutorial.

[MrIslomaniac]

oh thank you macklebee, didn't think of that =)

you saved my day

Hey, it's me again.

I did some coding, but i don't seem to get any collision working:

TBody Spectator = CreateBodySphere(0.1f);
SetBodyMass(Spectator,1);
SetBodyGravityMode(Spectator,0);
PositionEntity(Spectator,EntityPosition(cam));
SetBodyDamping(Spectator,10.0);

EntityType(Spectator,1);
EntityType(game.scene.scene,1);

TBody Sphere = CreateBodySphere();
PositionEntity(Sphere,Vec3(0,50,0));
ScaleEntity(Sphere,Vec3(10,10,10));
EntityType(Sphere,1);
SetBodyGravityMode(Sphere,0);

Collisions::Set(1,1,SLIDINGCOLLISION);

In DebugPhysics, they just go through each other.

Any idea?

Tried to set the body mass of Sphere?

[MrIslomaniac]

Thanks for your answer, but that does not work either =(

I am not a c++ guy, but I have some questions about your code. Is 'game.scene.scene' the actual entity you loaded with LoadScene()? Are you using lua inconjuction with c++? Have you tried just:

Collisions::Set(1,1,1);

just in case, SLIDINGCOLLISION is not being defined? Is the Spectator being parented to the cam?

[MrIslomaniac]

spectator is not parented, i move the spectator and place the cam at the new position.

I am using gamelib, which complicates things even more(e.g. slidingcollision).

But i just figured it out myself =)

the scene does not react on physics, i don't know why, it just doesn't

So i created them by hand and it worked

 

TBody spectator=CreateBodySphere();
SetBodyMass(spectator,1);
SetBodyGravityMode(spectator,0);
EntityType(spectator,1);
SetBodyDamping(spectator,1.0);
::Collisions(1,1,1);

TBody Sphere = CreateBodySphere(0.3049625f);
EntityType(Sphere,1);
SetBodyGravityMode(Sphere,0);
SetBodyMass(Sphere,0);

Now it works, thank you all

Well just found another "bug"...

All my physics object get stuck when they are too far away from the center(like 4000 units from the center)

any clue?

I can't move them anymore once they got stuck.

[macklebee]

what version are you using? this issue or one very similar was supposedly fixed for LE 2.32 according to this BugReport

 

Also, you may want to look at downloading the newton SDK and getting the latest newton.dll from it. A couple of bugs were fixed that caused fast moving objects to pass through terrain, and I am not sure if Josh has incorporated the newest newton.dll into the Leadwerks SDK.

I can't move them anymore once they got stuck.

 

SetWorldSize() is what you are searching for. Your objects are just stuck in the boundaries of your physics world

[MrIslomaniac]

YYa found that out too, thank you =)

All works now, my first project has been finished and shown to an audience at a competition. If i win, I will publish the program here

I am using gamelib, which complicates things even more(e.g. slidingcollision).

Slidingcollison is a LEO feature, not gamelib. Gamelib doesn't change any engine commands, but only adds new unique commands.
