simple addForceAddPoint

[AggrorJorn]

I'm trying to push an object forward. To do this I use the AddForceAddPoint command. I've searched the rest of the forum and I kind a get stuck with difining the force.

	pick=CameraPick(camera,Vec3(GraphicsWidth()/2,GraphicsHeight()/2,2.0),0,0)
if pick~=nil then
	if MouseDown(1)==1 then
		centerY=(GraphicsHeight()/2)
		if (centerY >= currentY) then 
			texty = 1
			campos = EntityPosition(fw.main.camera);
			force= Vec3(pick.x-campos.x,pick.y-campos.y,pick.z-campos.z)
			NormalizeVec3(force);
			force.x=10
			force.y=0
			force.z=0
			entity:AddForceAtPoint(force,pick.entity)

 

When I hold down the left mouse button and try to move a box, I recieve the error: index for obect is a valid filed or method.

Can someone tell me what I'm doing wrong here?

Change fw.main.camera to fw.Main.camera, when you have updated SDK from today.

also the position of the pick appears to be pick.position with pick.position.x, pick.position.y, and pick.position.z

Good to know, but that wasn't the problem I think.

Doe you mean that the pick arguments are wrong? If so, what should they be?

depends if you are running it outside of the editor or inside... outside appears to require uppercase and inside the editor requires lowercase

 

also this line:

entity:AddForceAtPoint(force,pick.entity)

will not work... that command is looking for two Vec3's... so its looking for this:

entity:AddForceAtPoint(force,pick.position)

So what is this all about? Are you saying if I run from engine.exe vs editor.exe the case is different? That's not cool.

[AggrorJorn]

Is this upper/lower case effecting other commands as well?

I forgot to mention that the script editor selects the following line after the error:

index for obect is a valid filed or method.

force=Vec3(pick.x-campos.x,pick.y-campos.y,pick.z-campos.z)]

thats why i told you above that the position of a pick is pick.position with pick.position.x, pick.position.y, and pick.position.z as its components... there is no pick.x. pick.z...

sorry, I'm not so good with this yet. Thanks for the help it's working now

no problem... i didn't realize you did not understand my post above... i see that you had asked about it, but i missed it.
