  • That looks like a construct 2 screen shot. But that action still exists in construct 3 afaik. construct.net/make-games/manuals/construct-3/system-reference/system-actions

  • On created is a trigger condition. It can't be used with other trigger conditions unless the event is converted to an "or" block, or in a subevent.

  • > ie: int(13.5451) gives you 13

    thanks for explonation of all system expressions

    i need receive: "13.5451"

    not 13

    Take out the int() part. If you know what an expression is you should be able to figure this out.

  • I wouldn't say always use only tilemaps or not, but tilemaps have specific advantages that you should take advantage of if it's suitable for your use. As always, there are multiple ways to go about implementing software, and the "best" way will always depend on your situation and goal.

    Ashley is vsync triple frame buffering something we have access to, or already built in? Ref: intel.com/content/www/us/en/support/articles/000006930/graphics.html

    Edit: Read some more and looks like double buffering is implemented by default in webgl, but doesn't resolve the drop to 30 fps on a missed frame.

  • Check your collision boxes in the animations editor. They can be different per animation frame as well if your sprite is animated.

    Make sure you don't have other conflicting behaviors active.

  • There's nothing wrong with using the CPU. The CPU is there to be used. Are you running into slowdowns? 7000 objects still seems within the realm of reason, although the line of sight checks could be causing you issues, as those have collision checks. With so many objects moving, some fps fluctuations would probably be reasonable and hardly noticable.

    The first thing that comes to mind is to add a condition filter out only the objects in range first to check line of sight on, then you're only checking on a few hundred at a time. Actually I'm not sure if collision/los checks can be optimized this way, so it would be nice if someone else could confirm.

    Why are you trying to make this work on low end platforms? If you want to target low end platforms, you don't do something that would push any limits in the first place. If you want to make a game about being able to collect thousands of dust particles, your idea by nature is not targeting low end platforms. Also, how do you define low-end? The computer you're working on? The cheapest phone you can buy today? A tablet from 10 years ago?

    Here's a quick example that runs fine on my machine at 10000 objects. I'm sure you don't need to cover the entire screen so you should be able to do with significantly less. Another simple option is to lower your target resolution, so you just don't need as many objects to fill the screen in the first place.

  • There is a limitation of memory. You're unlikely to be anywhere near of it being a concern.

  • pcgamer.com/what-is-microstutter-and-how-do-i-fix-it

    Basically, on a 60 fps sync, even though your system is capable of 60+ fps, if for whatever reason it fails to render any given frame on time for 60 fps (this can be a memory issue sometimes, or simply high load, background processes or overhead, there are many possible reasons that can cause this), it will skip that frame resulting in an effective 30 fps (half) for that instant, which is very noticable as stutter. Over the course of a second, it might only skip one or two, resulting in the 59, 58 fps you sometimes see. This is an oversimplified explanation, and there is a lot more you can read about if you want.

    For one thing, frame buffering is a type of vsync that should minimize these issues, but I'm not familiar if that's implemented on the software side or hardware side as far as Construct is concerned, so check your graphics card settings.

    Also see if you can enable adaptive vsync on the hardware side, that could be another possible simple fix.

  • Vsync is a limit to only render as many frames as your hardware can display per second, because additional frames won't be shown anyway. In Construct, a frame, or tick, is basically a run through all your events before repeating. If you turn it off, then your device will try to do that as fast as it can, regardless of what can actually be displayed. So of course it will use up all the processing power it can.

  • If you start with 10 and want it to be 0, you'll need to subtract 10. What does 300 skill need to be divided by to equal 10?

    You're going to want a basic understanding of algebra, or you're not going to get very far making a game.

  • Does an empty drawing canvas get drawn as a transparent sprite would, in terms of fill rate?

  • Accuracy=10-int(skill/10)

  • Using discrete coordinates should mostly bypass collision related issues entirely, so that would seem to be a good solution.

    I would argue that learning about the pitfalls of collisions and collision detection (and by extension the effects of fps and the concept of updates/ticks) is pretty fundamental, but that's just my opinion and it really depends on what your class is focusing on teaching.

    If I were to approach this issue with values rather than helper sprites, I would try to implement a flexible, automatic system. Assuming there are no situations where an enemy can come into contact with multiple platforms, use two instance variables to keep track of the lower and upper bounds to patrol. These variables can be set on collision with a platform object, based on the position and width of the platform. If the position of the enemy object exceeds these bounds, turn around (trigger once while true).

  • The drawing canvas object has everything you need. Paste everything to the canvas, then save image. What did you do?

  • Going to go out on a limb and suggest that if you need you ask this question, it's probably not something you will find Construct particularly suitable for.

    That said, if you can do it in JavaScript, you can do it in Construct.
