Hi. As the title says, is it possible to test which specific tiles in a tile map are in LOS, and get their poistion or ID?

Also, i have a question about arrays. I have a very large one, and i would like to specify as condition "for each xy" starting and ending in an specify position. I think ican do an event of "for each XY" and test if that XY is between the values that i specify in another condition, but , wouldn't that test all the XY of the array and have poor performance?

Thanks for your help.

You should check the blending example. Go File > New > "Example: Blend modes" and see how it's done

Though i have seen that example 100 times, it didn't work for me. Now i check it again because you told me and see that i was missing "force own texture in layer" and that was the damn problem. Seriously, thanks

An event with two conditions for each position:

This one would be up:

compare values: mouse.y < sprite.y-(sprite.height/2)*

is between range: sprite.x-(sprite.Width/2)*<mouse.x<sprite.x+(sprite.Width/2)*

and set the animation

*(this depends of the point of reference of the sprite, i'm supposing it's the center

For the rest of positions, you just have to make variations on that

I think that probably there must be a way to do it with layers and the blenders options and effects, but i'm terrible at it, so i can't help you. On the other hand, user "Somebody" made an awesome plugin effect that makes exactly what i think you want. With it you should just to have two exactly horses of differents colours on the same position, and use the plugin on the second one:

Hi. I'm new to the community, and i've been having troubles with something that in theory i'm sure that must be simple to do.

I have a background, and this three sprites. Let's say that white is the background. Sprite 1 is the player, and sprite 2 is always following the position of the player.

I want sprite 2 to be invisible, and when being over sprite 3, make it transparent for being able to see the player. I'm somehow sure that this is posible using layers, and the blending options and effects of construct 2, but i just can't get the solution. I will apreciate a lot any answer, thanks you!
