Making something just stay where it is

[bobthe2lol]

It wont work. I tryed applyforce to the entity's pos, but it jsut goes flying off to the left, so i dont know how i would get a variable of the entities pos when spawned that wont ever change, and make the entity stay there. How can i do this?

Well you'd need to persist it on spawning, using if(first()){Pos = entity():pos()}

Then, you'd need to subtract Pos from the entity's current position, Vec = Pos - entity():pos()

Then, applyForce(Vec + $Vec*5), to stabilise so you'd need to persist Vec as well.

If that fails, you'd need to multiply Vec by a number that varies on the entity's weight, but with chips I don't think that's needed.

Resulting in:
@persist Pos:vector Vec:vector

if(first()){Pos = entity():pos()}

interval(10)
Vec = Pos - entity():pos()

applyForce(Vec + $Vec*5)

Which should do fine, except bear in mind that chips generally spawn welded to a surface until you hit them with the physgun (Assuming they spawn on the world). In which case, the expression wouldn't move period from where it was spawned.

Thank you. I have the chips model set to a phx plate so ill have to use the multiplier, also whats with the if first() part?

[Lyinginbedmon]

first() triggers the if function when the chip is first spawned, so it sets Pos, which is then where the chip stays.

I see. Ok, well i cant get it to work, i want it to fly around with key commands.

So what i want it to do is:

Hover
point at my mouse
Fly at my mouse, like using forward()
fly at variable speeds, but all it does is flys slowly in a line back and forth... can you help me? I know im sorta asking for code, but i dont know what to do.

Give us the code you have so far.

I am now working on a project, where i want it to hover +50 in the z axis, but to be able to move around on the X and Y axis. I have this, but it just spazes when i use it.

@trigger all
if(first()){
Pos = entity():isWeldedTo()os()
}
X = entity():isWeldedTo()os():x()
Y = entity():isWeldedTo()os():y()
entity():setMass(0)
interval(10)
PPos = ((Pos - entity():isWeldedTo()os())*500)+vec(-X,-Y,50)
entity():isWeldedTo():applyForce(PPos + $PPos*5)

OOOps wrong section sorrryyyy!!!!

It might be because you're setting the mass to 0, pretty sure that's inadvisable
