[HELP] Moving a camera on a 2D axis - Rob_Maate - 25.11.2011
Yo.
I have a small drama:
I'm scripting currently a "guided missile" which starts in the sky and travels down to the ground.
It's launched > Heads @ a set location > Detonates on arrival.
This was all good, no bugs or anything.
The next step was to make the missile CONTROLLABLE, which has been quite a task lmao.
For camera movement, I'm using nCamera by Norn.
I'll post all the coding i've done so far to try and make this work

My code at the moment moves the camera around in a "dome" sort of shape, which is REALLY hard to actually control, and with the constantly changing camera angles it's bloody disorienting.
Lmao im sure the answer is simple, but im sitting here @ like 3 AM and I have no idea how to proceed
Cheers in advance

>:CCC ANYONE LMAO
Re: [HELP] Moving a camera on a 2D axis - Lorenc_ - 26.11.2011
I'm just going to say, eh? what do you mean? I guess you're trying to make something like a predator missle.
Re: [HELP] Moving a camera on a 2D axis - Rob_Maate - 26.11.2011
Similar, It's part of something bigger
But ye the part im stuck on is basically like a COD predator missile
Re: [HELP] Moving a camera on a 2D axis - Rob_Maate - 26.11.2011
Ideas more than welcome @ any point LMAO
Re: [HELP] Moving a camera on a 2D axis - MP2 - 26.11.2011
You can't really make something like this is SA:MP. SA:MP is server-sided which means there is a delay for every 'message' sent to and from the server. You're never going to get a smooth camera movement, and it's going to cause lag.
P.S It's AGM not ATGM.
Re: [HELP] Moving a camera on a 2D axis - Rob_Maate - 26.11.2011
Mate what I have is already smooth enough for me. I have done that by implementing a Z_FIX variable, setting the camera location to lower than the server believes it is at.
What I need to implement is the ability to move my endpoint on a camera-angle related x/y plane, rather than the x/y of the map itself.
