flower points bonuses

How do you think they would have done the flower pickups in Rodland? I was thinking animated tiles, but if you "picked up" one and replaced it with a blank or background tile, it would have replaced them all?

3 picked up

Can a similar thing be done in GBStudio?

thanks.

Hello,

I've got some basics working really well but just trying to improve performance if I can.

When actors are taken down by my player, a random number is generated if if it's of a certain set of values a power up is dropped. This is done by re-using the enemy actor, changing the animation state and re-activating it.

This sets a variable PUP_Active to true and collisions are enabled. The power up has a lifespan that is controlled by a wait instruction in the original power up set up script that enables it, and after X seconds, the actor is disabled again.

The player can collect it because the power up actor can still register collisions and if PUP_Active is true, this allows the player to collect it and that then adds the power up/points etc. This can all happen whilst the Wait instruction is otherwise waiting.

Hope that makes sense.

My issue is that performance visibly decreases when that power up actor is in a waiting state. To see if it was the Wait instruction, I changed the Wait to a timer event, and that had better performance i.e the player's jumping and movement was smoother in this situation than a power up in Wait state.

Is using timers the only way I can improve performance vs Wait?

I noticed there is a GBVM command, GBVM_Idle I think with a parameter for the number of frames but when using it in GBStudio it only works without a parameter (i.e 1 frame).

Thanks.

Hello,

I want to draw a points bonus indicator using an actor, like in Bubble Bobble or Rodland when you collect a bonus, the points are shown briefly rising from the sprite's former position:

One way I thought of doing this was creating predefined values as animation states, and then switching the points bonus actor on, moving it into position, change the animation state to 10, 20, 50 etc. and then animate it a little by moving it and then hide it again.

But I can only select animation states from a drop down, not by a variable.

Is this possible?

Or is there a better way of accomplishing this idea?

Thanks.

Hello,

Is it possible to write white text on a black background with DrawText?

I read here https://gbstudiolab.neocities.org/guides/gbvm-overlay-hud-2 that escape code \007\002 should do this but it still appears as black text on a white background.

Hello,
I want an actor to drop down from the top. As it's a power up I want it to collide with walls so if it falls on a platform it stops there. The easiest way to do this is an Actor Move To event. This works great but the Tiles Y property could vary from scene to scene, 17 might be the "maximum" Y position on some scenes, others it will be more.

I can fudge it saying something like a Y position of 100 tiles but that seems a bit naff.

If I could read the height in tiles into a variable and use that instead it would feel more solid.

Thanks.

Hello,

In my game, the player traps the enemy with a projectile, which is a state that lasts for say 5 seconds, the last 1.5 seconds of which are done with Actor Effect Flicker to signify to the player that if they don't hurry up and bonk the enemy on the head, they will reactivate.

However, if the player does strike them in the flickering state, I then have a function that reuses the actor and randomly generates a power up. However because this occurs once Actor Effect Flicker has been called, when the power up appears, it's still flickering for a little bit.

Is there a way to cancel an active actor effect like:

To illustrate the issue.

I have two enemy actors, Actor 1 and Actor 2, both are the same design and use the same sprite sheet and initial animation state.

As an initial test, if in the On Init event for the scene I change one of them, Actor 1 to use the "pup" (power up) sprite sheet, and set the animation state to "coin" - as you would expect, only one of the Actors, Actor 1, changes its sprite sheet and animation state.

Actor 2 remains unchanged. This is what I would expect.

https://preview.redd.it/hut3ly23h8hh1.png?width=692&format=png&auto=webp&s=36007b2371e1581bd0a43f06a849c1b4d168e4ee

Here when the game starts, Actor 1 has become a coin (top middle), whereas Actor 2 has remained an enemy (bottom left).

This is what I'd expect, as I am targeting a specific Actor to change its sprite sheet and animation state.

However I have an issue with the same thing when called in a script. I have created scripts to handle Enemy collision, and the generation of power ups on defeating an enemy, this all works great, except if I do the same sprite sheet and animation state swap in a script, the other enemy actor's animation/visual appearance gets corrupted.

So to illustrate what I've done. When the player themselves hits the enemy, it causes a collision and this script is called. As you can see an Actor is passed in as a parameter, so for example for Actor 2, EnemyStompHit is called like so:

https://preview.redd.it/bc85p62il8hh1.png?width=676&format=png&auto=webp&s=4e31213db87a5664732efaa88d7dcf81fe8b6e3c

You can see Self (Actor 2) is passed in parameter Enemy Actor.

In the EnemyStompHit script a random number is generated for the time being if that number is above zero, a Power Up is created in the enemy's stead. It reuses the actor, by manor of deactivating its enemy state, setting a local variable PUP_Active to the actor that it has become a PowerUp and most importantly calls a second Script called PowerUp which itself takes the Actor parameter (Enemy Actor)

https://preview.redd.it/vq3704vzi8hh1.png?width=484&format=png&auto=webp&s=d60d5473907c9e7d055f8375abd535bef9ff543b

The PowerUp script is there to change the animation state and sprite sheet to reflect the type of power up the random number signifies. It too takes the Enemy Actor parameter.

The drop down for the AnimationState change is as follows:

https://preview.redd.it/wisjr6scj8hh1.png?width=692&format=png&auto=webp&s=1393aea16c8642afa0c2cc271141627fc908a88d

So in theory, this is doing exactly the same thing as the OnInit test but just with more logic around it. However, on hitting the enemy and a Power Up being generated, Set Sprite Sheet seems to corrupt the other enemy actor sprite as well as correctly changing the targeted actor to a coin. Note the player sprite is unaffected.

In my case, both Actor 1 and 2 share the same sprite sheet as sometimes you have enemies of the same design but as indicated in the initial OnInit callback script just to test the functionality, that works as expected.

I am using GBStudio 4.3.2.

Thanks.

Hello,

I've been making some progress on my project but I have an issue with projectiles.

I have a script which is called on init:

https://preview.redd.it/lud9x8difzgh1.png?width=702&format=png&auto=webp&s=71fe068ad0481fc575d4c72234b6177e4dbae7c0

This bubble sprite looks as follows:

When the player hits the B button a projectile is due to fired as below:

But what I get is a corrupted version of the player sprite:

I can't see where I've gone wrong. Any ideas?

Does the projectile have to be part of the player sprite sheet?

Thanks.
