When moving diagonally using the 8-directional movement preset, I notice in my game that the camera jostles very noticeably while it follows the player. is there any way I can minimize/eliminate this? it's not annoying now but I'm sure it will be later on when more scenery is added. Thanks for your time, guys. I'm new to this forum and it seems very friendly here.
Hi! Welcome to the forum.
Without seeing your code, my recommendation would be to create an active object called "Camera." Set the scrolling X position to its X position, and the scrolling Y position to its Y position, instead of the player. This way you can control the camera separately from the scrolling, and you can interpret the camera's position based on the player position, rather than making it 1:1. Using this technique, you can ease the camera in and out based on range from the player, add in some trig to smooth scroll it at different angles, etc.
Check out the "Expressions" section of this site to help you set up some really smooth trig functions that'll make for a great camera: http://www.sketchy.co.nf/
Alright, thanks for the help.
I hate to post so inefficiently like this, but I added smooth scrolling in the form of a camera object and the scrolling works fine... but the problem I think is the movement system, as it seems that the player will noticeably skip pixels in his movement. I think this may be because I am using a small resolution for the frame (256x224), but I'd hope that there might be a fix to at least make it less... jostled. Any ideas? I'm thinking making my own movement system might be the way to go but I'm much too inexperienced to understand how to get rid of this pixel-skipping.
Is your player moving at a slow speed? If so, this might simply be the nature of "floating point movement" being noticeable at low velocities. Since movement uses "in-between" values before shifting whole pixels (i.e moving 1 pixel over 2 frames instead of 1) it can appear "jagged" when moving diagonally, because there are some frames where the object might not be moving at all on one axis but is on the other, etc.
Reading about your "pixel skipping" though I doubt that's what is causing it. Try this:
click on your frame in the workspace toolbar and go to the "runtime options" tab in frame properties. Uncheck "timer-based movements" and see if this helps. The option applies Delta Time to the clickteam movements, so they always run at the same speed, even when framerate changes. This might be causing your "jostling".
This might also be because of the significance of moving one pixel at a low resolution compared to a high resolution. You can't move an object less than 1 pixel directly, however you CAN use sub-pixel positioning to smooth things out. It's a lot simpler than it sounds. Instead of setting X("player") to X("player")+1 or -1 for movement, create a "MovementSpeed" value on the player. Set this to, say, 2.5, or some other non-integer value. Then set X("player") + movementSpeed("player"). Things will look a heck of a lot smoother.
