Dealing with multiple enemy shots?

waldron

@Dave so the player controls for that one is

plr.vel += {j.lx,0}
plr.pos += plr.vel
plr.vel += *= 0.9``
i tried j.ly but it just go's diagonal lol

waldron

cant get either of these scrolling

Dave

And you've definitely tried the

plr.vel += {j.lx, -j.ly} // must be negative y to move up the screen properly

Could be weirdness happening with sprite camera, is that what you're using to scroll?

I would recommend using the sprite poperties rather than ther player structure from the program instead. So just this for the setup:

plr = createSprite()

And then for the controls:

plr.x_speed += j.lx * speedMultiplier
plr.y_speed -= j.ly * speedMultiplier
plr.x_speed *= 0.9
plr.y_speed *= 0.9

See if that changes anything. I wrote that demo for Steve before I really knew how t use the sprite properties to full effect. To be honest, it shouldn't make a difference. Hard to know what exactly is going wrong without seeing the code.

waldron

@Dave cheers i tried the -j.ly but not in the same bracket, yeah im using an invisible sprite set to move up its proving to be a royal pain but really want to run the program this way. i'l try that code and see what happens ;) thanks again

waldron

@Dave beautiful movement works, but now the bullets problem when scrolling.
can i set a sprite at the top of the screen moving the same speed as the camera sprite but set that to removesprite bullet?

Maxwello

If I remember rightly (from somewhere) you had set the bullets to travel something 15 or something, can that be made variable based on your y position from centre to fix the issue (from what I saw on the vid) of the bullets not travelling as far as they should?

waldron

@Maxwello at the moment the bullets are set at a distence of -200 which removes them at that distance, so iv increased that to -2000000 lol and increased the amount of bullets to 2000000 lol it works but will definitely cause problems some where down the line.

if i can figure out to do it as you quoted that would work, the actual player sprite firing moves so if i set it at -300 that would be enough

Maxwello

Make it - 200 + gheight/2 - y.pos or something maybe
Sorry I'm so vague I barely get near my switch lately and I'm a bit dizzy today lol

waldron

@Maxwello iv shared the program- LTG53MND5U im still learning myself so incorporating changes can be a little difficult untill i understand the code better

Maxwello

Sweet I have been following your progress on this game so I'll deffo take a look thanks man
