|
I'm trying to make an adjustable camera for a racing game. I have found the camera and the car's coordinates. The script reads the car's coordinates, then writes it onto the camera's coordinates.
It looks normal on a stand still, but once the car starts moving, the camera stutters. I have already NOP'd the opcodes that writes to the camera coordinates.
I tried reducing the stutters with the solutions from this thread :
forum.cheatengine.org/viewtopic.php?t=606924
Which reduces some of the stutter but still present.
Here is the lua script used, controls to adjust the camera is yet to be implemented :
| Code: | globalalloc(cheaton,4)
cheaton:
dd 0
{$lua}
if syntaxcheck then return end
[ENABLE]
local node = getAddress("69EC9A50") // Get XYZ coordinates.
local calcX = readFloat(node + 0x40)
local calcY = readFloat(node + 0x48)
local calcZ = readFloat(node + 0x44)
--packwrite script by panraven
function packWrite(addr, fms, ...)
local packed = addr and string.pack(fms,...)
if packed then return writeBytes(addr,{packed:byte(1,-1)}) end
end
createNativeThread(function(timer)
sleep(200)
while readFloat("cheaton") == 0 do
sleep(6.65)
local node2 = getAddress("69E4BF10") // Get the car's XYZ coordinates.
local carx = readFloat(node2 + 0x00)
local cary = readFloat(node2 + 0x04)
local carz = readFloat(node2 + 0x08)
calcX = carx
calcY = cary + 12 //Offset camera height to hood
calcZ = carz
packWrite(node + 0x40, 'fff', calcX, calcY, calcZ) // Write the new values onto the camera's coordinates.
end
end)
[DISABLE]
{$asm}
cheaton:
dd 1 |
Here is the video showing how it looks, epilepsy warning btw : youtu.be/L_YIYLXWk8o
Looking for some help on this, thanks in advanced!

At a guess, it might be because the timer isn't synced to when you are rendering each frame: I'd see if you could find somewhere you can stick some instructions that run for each frame.
Maybe use the opcodes you NOPed out to set the camera position to jump somewhere and jump back?

Thanks for the advice! Matching the timer to the game's framerate does reduce the stutter a lot. Its still present but only when the game has a minor drop in framerate.
Oh and yeah, I forgot to mention, the game heavily relies on the framerate (60fps), as game speed is tied to it.
I will try the instructions method later
