Sprites - Help!

Willpowered

Sure thing! First, you'll need to create an empty map using the map editor. Then in your code you'll need to load it with loadMap(map_name) and call collideMap(my_sprite) to refresh the collision data.

Here's how I would update the swimmer collision example earlier in this thread to work around the problem:

map = loadMap("test") // Load an empty map created with the map editor.

img = loadImage("Untied Games/Swimmer A")

spr1 = createSprite()
setSpriteImage(spr1, img)
setSpriteAnimation(spr1, 14, 27, 10)
setSpriteCollisionShape(spr1, SHAPE_CIRCLE, 100, 100, 0)
spr1.x = 1920 / 4
spr1.x_speed = -100

spr2 = createSprite()
setSpriteImage(spr2, img)
setSpriteAnimation(spr2, 14, 27, 10)
setSpriteCollisionShape(spr2, SHAPE_CIRCLE, 100, 100, 0)
spr2.x = -1920 / 4
spr2.x_speed = 100
spr2.xscale = -1

setSpriteCamera(0, 0, 4)
centerSpriteCamera(0, 0)

while true loop
    
    clear(0, 0, 0, 0)

    // Colliding these sprites with an empty map will not affect them, but it will properly refresh their collision data.
    collideMap(spr1)
    collideMap(spr2)
    
    result = collideSprites(spr1, spr2)
    if result.exists then
        spr2.visible = false
    endif
    
    updateSprites()
    drawSprites()
    update()
    
repeat

Ah i was only calling collideMap once and not in my game loop. This helped, thank you!

Nice, glad you got it working! When I have an ETA on when the fix for this issue can be deployed, I'll let everyone know.

I have a question about sprite animation.

I have a sprite that is animating through frames correctly when idling.

When I detect control input say c.right I set the sprite animation to the corresponding right direction frames. And set the location. The sprite is moving to the right but no longer animates until I stop pressing c.right. I assume each time I update the sprite location it's resetting the animation to it's first frame.

I've looked at example code and can't spot what I am doing wrong.

@sys64738 the resetting of the animation is more likely from assigning the frame when detecting the key press.

@Discostew yeah that's it. Trying to figure out best way to stop it retriggering. Guess a Boolean switch will do for now

@Martin == vs = is the oldest trap in the book! Some compilers now warn you about this one

Martin

I don’t know why my brain just assumes because it’s basic, it’s should be a single = and somehow magically know the difference!

Was this ever resolved. Just got collisions working in my latest project and then turned off show collision boxes. And well here I am with same problem as Martin.

Edit have loaded an empty map as above. And added


for x = 0 to 10 loop
collidemap(bubblesprite[x])
Collide = detectspritecollision(subsprite,bubblesprite[x])

And it works very occasionly for a bit then doesn't

Martin

I am told that it is resolved in the next patch that has been submitted for review.

It works 100% of the time for me when using what you have done. I do also collide subsprite with the map as well however. Maybe try that?

@Martin oh brilliant that was the problem, I didn't collidemap the sub, so obvious in hindsight! thank you!
