Dealing with multiple enemy shots?

SteveZX81

Here is my code now.

When I press the shoot button I get
--Error --
Line 108
Function N/A
Operation not recognized.

I will have to play about with this after work - i think that might be why I was using Will's method of assigning the nullSprite in the first place.

[edit] While you wait go back to assigning all empty slots to nullSprite and see if that works. The more I think about it, the more I think that's why I used that method in the first place. You will still need to break out of the loop with the 'foundSlot' boolean. But i have a feeling it is not liking you trying to assign a sprite handle to something that has previously declared as a bool.

Mornin' @SteveZX81! I just shared a program called "particleLaser Sprites" which gives detailed comments on every section.

It's not doing any collision with enemies, but there is a commented out example for where the collision code would be.

Hope it helps mate, let me know if I can expand on anything in there.

oh Dave, you're too good to me! Thank you.

@Dave Hi Dave. Where did you share "SpreadLaser Sprites"

Martin

Back then it would have been a user share as we did not have community sharing. If @Dave still has it then maybe he could re-share using an ID now?

SteveZX81

@BildoCZ I might still have it, I'll check my Switch watch this space.

Edit: I do have it and I have now submitted it, the code is UQP63MNF6D but give it a few hours to clear the 'pending' state.

Dave

@SteveZX81 - Life saver. I deleted the program recently as I was cleaning up my projects (I tend to make a lot to test individual things).

Hope it helps @BildoCZ ! Let me know if you need anything

@SteveZX81 just downloaded it, looks good love the comments should be able to use this for my program hopefully

BildoCZ

Thx all.
I'm a beginner in FUZE. But I used to work in Game Maker. :)

@Dave so i'm using the laser program for my scrolling top down game to get my plane to shoot but i cant get the y axis movement working? apart from that it works great.

Dave

@waldron Y axis movement of the bullets you mean? I'll hae to check the program again as i've forgotten the details. Will download now

Dave

Hmm - the example doesn't use sprite properties to their best effect at all. It'll work, but it should really be using the properties of the sprites properly. I'll whip up another example a bit later and post the share code on this thread.

waldron

@Dave no the bullet direction is fine its just the ship movement i'm having trouble with the up and down movement tried all sorts

Dave

Give it a share and message me the share code if you like @waldron

Is it after adding the other code that the y axis movement stopped working, or are you y et to actually have it working as you wanted?

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
